Driving in Saint Martin
The border between French Saint-Martin and Dutch Sint Maarten is marked by a small obelisk and, depending on which road you take, a faded sign that you will probably miss if you are not looking for it. There are no customs, no checkpoints, no passport stamp, no change in road surface. One moment you are in France, the next you are in the Netherlands. Your rental car does not care, your insurance does not care, and neither does anyone else on the road. We crossed the border eleven times in one day, mostly because the French side had the better lunch options and the Dutch side had the better parking.
Saint Martin is a driving destination in miniature. The entire island is 87 square kilometers, the main road circuit is about 60 km, and nothing is more than 30 minutes from anything else. The challenge is not distance – it is navigation through narrow island roads, hilly terrain, and traffic that compresses surprisingly into a very small space.
Road Rules at a Glance
| Rule | French Side (Saint-Martin) | Dutch Side (Sint Maarten) |
|---|---|---|
| Side of road | Right | Right |
| Speed limit (town) | 50 km/h | 40-60 km/h |
| Speed limit (outside town) | 70-80 km/h | 60-80 km/h |
| Seatbelts | Mandatory | Mandatory |
| Blood alcohol limit | 0.05% | 0.05% |
| Mobile phones | Hands-free only | Hands-free only |
| Minimum driving age | 18 | 18 |
| Headlights | Required in poor visibility | Required in poor visibility |
| Child seats | Required for children under 10 | Required for children under 10 |
The rules are essentially the same on both sides. Both sides drive on the right. Both use standard international road signs. The main practical difference is that the French side uses kilometers and the Dutch side has a mix of kilometers and miles on older signs, though newer signs are in kilometers.
Blood alcohol in practice: The 0.05% limit applies on both sides. This is stricter than the US standard (0.08%) but in line with most of Europe. On an island where taxis are available and hotels are never far, there is little reason to drive after drinking.
The Border (or Lack Thereof)
The Treaty of Concordia (1648) divided the island and established free movement between the two halves. There are no border controls of any kind. You will cross the border repeatedly without noticing. The only ways to tell which side you are on:
- Language on signs: French in the north, Dutch/English in the south
- Road condition: Sometimes subtly different (the French side has benefited from EU-funded road maintenance)
- Restaurant menus: Euros on the French side, dollars on the Dutch side (though both currencies are accepted everywhere)
- Architecture: More European on the French side, more Caribbean commercial on the Dutch side
- Phone network: Your SIM may switch networks as you cross, which can result in roaming charges if you have an EU or US carrier
Your rental car, insurance, and license are valid on both sides without any additional documentation.
The Treaty of Concordia backstory: Legend has it that the island was divided in 1648 by a walking contest – a Frenchman and a Dutchman started back-to-back from Oyster Pond and walked in opposite directions around the coast. Where they met determined the border. The Frenchman allegedly covered more ground because Dutch hospitality had provided more wine stops. The French ended up with 57 square kilometers and the Dutch with 34. Whether the legend is true (it probably isn’t) is debated; the result (France got more island) is not.
License Requirements
US and Canadian licenses: Valid on both sides without an IDP. Saint Martin is one of the few international destinations where a US driver’s license alone is sufficient.
EU licenses: Valid on both sides.
UK licenses: Valid on both sides (post-Brexit, the UK license is still accepted on the Dutch side as standard and on the French side by common practice).
Australian, New Zealand, and most other licenses: Valid on the Dutch side without an IDP. The French side technically requires an IDP for non-EU, non-US licenses, but enforcement is relaxed and most rental agencies accept non-EU licenses without an IDP. If you are from Australia, New Zealand, South Africa, or similar countries, bringing an IDP is prudent but may not be strictly checked.
Rental requirements:
- Minimum age: 21 (some agencies 25 for certain vehicle categories)
- License held for at least one year
- Credit card for deposit
- Valid passport
Road Conditions
Saint Martin’s roads are a mix of reasonable main roads and narrow, steep secondary roads. The island is hilly – hills is perhaps an understatement for Pic Paradis at 424 meters, but the terrain rises sharply in several parts of the island.
Main ring road (Route Nationale / main highways): The road that circles the island is paved and generally in good condition. Two lanes, with occasional sections widened to four lanes near the airport and Philipsburg. The French side tends to be slightly better maintained due to EU road maintenance funding.
Secondary roads: The roads leading to beaches, hillside neighborhoods, and viewpoints can be narrow, steep, and winding. Some beach access roads are unpaved or have rough surfaces. A few roads in the French hills above Marigot are single-lane with blind corners requiring backing up if you meet oncoming traffic.
Post-Hurricane Irma condition: Hurricane Irma (2017) devastated the island. Most road infrastructure has been rebuilt, but some secondary roads still have patches and uneven surfaces from 2017 and subsequent weather. The main roads are fully restored.
| Road Type | Condition | Notes |
|---|---|---|
| Main ring road | Good | Both sides, well-maintained |
| Town streets (Philipsburg, Marigot) | Good-Fair | Narrow, one-way systems |
| Beach access roads | Variable | Some unpaved, some steep |
| Hill roads (French side) | Fair | Narrow, winding, scenic |
| Simpson Bay area | Good | Busy, well-maintained |
| Pic Paradis approach | Fair-Poor | Rough, single lane in places |
Specific road hazards:
- Speed bumps (sleeping policemen): Everywhere, especially at town entrances, school zones, and resort entrances. Some are very pronounced. Slow down significantly.
- Potholes: Variable. Main roads are generally good; side roads may have significant potholes, particularly after rain or in areas still recovering from hurricane damage.
- Narrow beach roads: The road to Baie Rouge, Baie Longue, and some smaller beaches becomes a single track at the end. Slow down, watch for oncoming cars.
- Steep hills: Several areas have 15-20% gradient hills, particularly on the French side. Manual transmission would be challenging; automatic handles it easily.
Speed Limits
| Zone | Limit | Notes |
|---|---|---|
| Town centers | 40-50 km/h | Both sides |
| Residential areas | 30 km/h | School zones, side streets |
| Main roads outside town | 60-80 km/h | Both sides |
In practice, you will rarely exceed 60 km/h on Saint Martin. The roads are short, the turns are frequent, and the traffic keeps speeds low. Speed bumps at town entrances physically enforce the limits.
Speed enforcement: Saint Martin has a relatively small police presence compared to major destinations. Traffic enforcement exists but is not aggressive. That said, speed bumps are the primary enforcement mechanism – drive over one at 60 km/h and you will understand immediately why they work.
Fuel
| Fuel Type | Dutch Side Price (per liter) | French Side Price | Notes |
|---|---|---|---|
| Unleaded gasoline | ~$1.30-1.50 | ~EUR 1.60-1.80 | Dutch side cheaper |
| Diesel | ~$1.10-1.30 | ~EUR 1.40-1.60 | Fewer diesel rentals |
Fuel stations are found on both sides, concentrated near the main towns. The Dutch side is generally cheaper for fuel due to different tax structures (the French side’s fuel is subject to EU-adjacent taxes; the Dutch side’s tax is lower as an overseas territory).
Fuel reality on Saint Martin: Given the island’s size, fuel is a minor expense. A full tank (40-50 liters) will last an entire week of island driving. A compact car’s full tank costs approximately $55-75 and you will probably fill up once during a week. Your total fuel budget for a week’s rental is $50-80.
Fuel station locations:
- Dutch side: Simpson Bay (near airport), Cole Bay, Philipsburg area
- French side: Marigot (near the roundabout), Grand Case, Sandy Ground
Parking
Philipsburg (Dutch): Tight. The main street (Front Street) has very limited parking. Use the lots near the cruise terminal or the residential streets behind the main strip. On cruise ship days (check ship schedule), parking is essentially impossible near the waterfront. Arrive before 9 AM or after 4 PM to have any chance of easy parking.
Marigot (French): Slightly easier. The waterfront has a parking area and there are lots near the market. Still tight during market days (Wednesday and Saturday mornings, 7 AM-1 PM). The Fort Louis hill approach road has free parking with a walk down to town.
Simpson Bay (Dutch): Easiest of the three main areas. Shopping plazas and restaurants have their own lots. The resort hotel lots are generally large enough. The Simpson Bay Lagoon drawbridge area has roadside parking on both sides.
Beaches: Most beaches have free parking lots or roadside parking. Orient Bay has a large lot (free, occasionally fills in peak season). Maho Beach has a lot near the airport fence. Smaller beaches may have informal roadside pull-offs.
Parking table by area:
| Area | Typical Cost | Notes |
|---|---|---|
| Orient Bay | Free | Large lot, usually adequate |
| Maho Beach | Free | Airport fence lot |
| Baie Rouge | Free | Small lot at end of access road |
| Marigot waterfront | Free | Fills early |
| Philipsburg Front Street | Free-$2/hour | Difficult on cruise days |
| Simpson Bay shopping plazas | Free | Ample space |
| Grand Case main strip | Free | Street parking, limited on weekends |
| Hotel lots | Free (guests) | Standard |
Traffic Culture
Saint Martin driving is Caribbean: relaxed, informal, and occasionally improvised. Drivers yield to each other with hand gestures. Honking is common but friendly (short beep = “I’m here” or “thanks”). Traffic rules exist but are loosely enforced.
The main traffic challenges:
Cruise ship days in Philipsburg: When multiple ships are in port (primarily Tuesday-Saturday, peak season), the roads near Philipsburg become gridlocked. Check the cruise ship calendar (available at any hotel or online). On heavy cruise days (three or more ships), avoid the Philipsburg area entirely between 9 AM and 4 PM. This is not being alarmist – the island’s narrow approach roads cannot absorb 5,000-8,000 additional people simultaneously.
Airport area congestion: The Simpson Bay area near Princess Juliana Airport is the busiest part of the island. The airport road handles flight arrivals, cruise ship transportation, hotel pickups, and local traffic simultaneously. Morning arrivals (9-11 AM) and evening departures (4-7 PM) create the most congestion.
The Simpson Bay Lagoon drawbridge: The bridge on the main causeway between Simpson Bay and Cole Bay opens for boat traffic twice daily (approximately 9-9:30 AM and 5-5:30 PM, but times vary). When it opens, traffic stops for 15-20 minutes. If you are caught in this, you wait. If you know it is due, use the Airport Road route instead.
Rush hours: Morning (7:30-8:30 AM) and evening (5-6 PM) commute traffic, concentrated on the main roads between the French and Dutch sides. For an island of 77,000 people, the commuter traffic is surprisingly real.
Roundabouts on the French side: The French side uses roundabouts at most major intersections. Traffic inside the roundabout has priority (yield to traffic from the left when entering). If you are not used to European roundabout rules, the French side will be your practice ground.
Pedestrians at beaches: Near popular beaches, pedestrians cross the road freely and without much warning. Slow down when approaching beach access areas.
Driving to Specific Destinations
Orient Bay by car: From Marigot: 20 km, 25 minutes on the main road north then east. The approach road to Orient Bay is a two-lane road through a residential area. Parking is in the large lot at the beach entrance.
Maho Beach by car: From Simpson Bay airport: 3 km, 5 minutes west on the airport road. The simplest drive on the island. The beach is right at the runway approach. The parking lot is signed from the road.
Grand Case for dinner: From Simpson Bay: 20 km, 25 minutes. The town has one main street (Boulevard de Grand Case). Parking is on the street or in the small lot at the north end. In high season on weekend evenings, arrive by 7 PM or expect to circle.
Pic Paradis: From Rambaud village on the French side. The road climbs steeply through forest, becomes progressively narrower, and requires careful driving. A small SUV handles it better than a low-clearance sedan. The road ends at a parking area from which you walk to the summit.
Baie Rouge: From Marigot: 10 km, 12 minutes southwest. The last 300-400 meters of the access road is unpaved but manageable for any car at low speed. Parking is at the beach.
Emergency Information
| Service | French Side | Dutch Side |
|---|---|---|
| General emergency | 112 | 911 or 919 |
| Police | 17 or 0590 87 81 11 | 911 |
| Ambulance | 15 | 912 |
| Fire | 18 | 919 |
Two different emergency systems for one tiny island. If in doubt, use 112 – it works on both sides and operators can connect you to the relevant local service.
Accidents on Saint Martin: Minor accidents (fender benders in tight parking, small scrapes) are not rare on an island with narrow streets. If you have an accident, take photos, exchange information with the other driver, and call your rental agency. The police are called for significant accidents; for minor incidents, a mutual agreement and photos are typically how things are resolved. Your rental agency emergency number is in the agreement.
Vehicle breakdowns: The island is small enough that breakdown assistance is quick. Your rental agency should have a local number. If you break down on a main road, push the car off the road if possible, turn on hazard lights, and call the agency. You will be attended to quickly.
Seasonal Considerations
High season (December-April): Dry season, best weather, most tourists, highest rental prices. Traffic is heavier, particularly around Philipsburg and Simpson Bay. Cruise ship frequency peaks. Book rental cars 2-4 weeks ahead for high season.
Shoulder season (May, November): Good weather, dropping prices, fewer crowds. May in particular has excellent beach conditions with minimal crowd. Thanksgiving week (US) in late November brings a sharp spike in American visitors.
Low/hurricane season (June-October): Wetter, hotter, significantly cheaper. Hurricane season runs June through November, with peak risk August-October. Most rental agencies do not rent during active hurricane warnings and will refund or waive fees if a storm forces closure. September is the quietest month.
Best for driving: February-April offers the optimal combination of dry weather, warm temperatures, settled seas for beach swimming, and manageable (though elevated) tourist levels. Early December is excellent before the Christmas rush begins around December 20.
Navigation on Saint Martin
GPS and apps: Google Maps works well on Saint Martin and knows the island’s roads. Apple Maps is also functional. Given the island’s small size and limited road network, navigation is relatively simple – most destinations are reached by following the main coastal road and turning off at signed junctions.
Road signs: The French side has signs in French (standard European sign format). The Dutch side has English-language signs. Street names are posted but the island’s informal culture means people often navigate by landmarks (“turn at the Maho Beach bar,” “pass the roundabout after the gas station”).
Best navigation tip: Learn three key points – Princess Juliana Airport, Marigot waterfront, and Orient Bay – and you can locate yourself anywhere on the island relative to those landmarks.
Understanding Caribbean Island Driving
Saint Martin is a Caribbean island, and Caribbean driving comes with its own conventions that differ from European or North American norms. Being aware of them helps.
The relaxed pace: Caribbean drivers do not rush. If someone stops in the middle of the road to have a conversation with someone on the sidewalk, this happens. If someone is looking for a parking spot and simply stops while they think about it, this happens too. Horns are not used aggressively – a short beep is friendly (“I’m here”) rather than angry. Traffic flows more slowly and more organically than on the continent.
Improvised right-of-way: At informal intersections and unmarked junctions, right-of-way is negotiated by eye contact and hand gestures rather than strict rule application. This is not chaos – it is a system that locals have developed and that works with sufficient mutual awareness.
Motorcycles and scooters: Both are common on Saint Martin, especially among locals. They filter between lanes and come from unexpected angles at intersections. Leave extra margin around motorcycles.
Speed bumps: They are everywhere. Most are unpainted or only faintly marked. Approach any intersection, school, or settlement at reduced speed and expect a speed bump. Hitting one at 50 km/h in a small car is unpleasant; hitting one at 50 km/h in a Jeep is worse.
Night driving: Saint Martin is safe to drive at night, but lighting on secondary roads and beach access roads is minimal. If you are going to a remote beach at night (for a stargazing trip or a late dinner venue), bring a flashlight. The potholes that are visible in daylight are invisible at night.
Saint Martin’s Road System Explained
For an 87 square kilometer island, the road system is more complex than you might expect. Understanding the main routes helps:
The main ring road: A continuous paved road circles most of the island. It connects Simpson Bay (Dutch side) to Marigot (French side) to Grand Case (French north) down the east coast to Orient Bay, Oyster Pond (border), Dawn Beach, and Philipsburg (Dutch south), then back to Simpson Bay. This road is the backbone of island navigation.
The Terres Basses peninsula (French southwest): The southwestern tip of the island is a quiet peninsula of residential villas and hidden beaches (Baie Rouge, Baie Longue). The road loops around it – enter from Marigot direction or from the Simpson Bay direction and circle the peninsula.
The French north: The road from Grand Case continues north to Anse Marcel. This is the quietest part of the island – a narrow, winding road through hillside vegetation leading to a secluded bay.
The Pic Paradis interior: Roads from Rambaud village climb toward the summit. These are the most challenging roads on the island – narrow, steep, and used mostly by the few residents of the hillside communities.
One-way systems: Marigot and Philipsburg have one-way street sections in their historic cores. GPS handles navigation through these.
Renting vs. Hiring a Taxi
For visitors spending 5+ days, a rental car is almost always more economical and more flexible than taxis. But a quick comparison:
| Factor | Rental Car | Taxis |
|---|---|---|
| Day 1 cost (airport, hotel, two beaches) | $55-75 (included in daily rate) | $80-120 (multiple separate fares) |
| 5-day total (average use) | $300-500 (all in) | $400-700+ (multiple daily fares) |
| Flexibility | Complete | Depends on availability |
| Beach to beach | Easy | Time-consuming coordination |
| Night out (Grand Case, return) | Drive, then don’t drink | Taxi each way: $20-30 each |
| Knowledge of island | You develop it | Driver knows shortcuts |
When taxis make sense: For a single-night dinner outing when you want to drink. For the first day before you have figured out navigation. For airport transfers if you are not renting. Beyond these specific cases, a car is more economical from day two onward.
Driving in Bad Weather
Saint Martin’s weather is generally excellent (dry season December-April, wetter season May-November). When weather is bad, it tends to be brief tropical showers rather than extended grey drizzle.
Rain driving: Tropical showers are intense but short (usually 15-30 minutes). Pull over if visibility drops significantly. Roads drain quickly in the tropics but can be slippery immediately after rain starts (oils on road surface before they wash off). Beach access roads become slippery when wet.
Hurricane season: If a tropical storm or hurricane is approaching, the airport closes and car rental agencies cease operations. The agencies’ cancellation policies for weather events are generally generous – verify at pickup. Most travel insurance covers hurricane cancellations.
After storms: After any significant rain event, check road condition before heading to beach access tracks or the Pic Paradis road. Fallen branches, washouts, and mud can temporarily block secondary roads.
Driving Etiquette and Local Customs
Understanding how locals actually drive on Saint Martin makes the experience smoother and reduces the risk of unnecessary friction.
The wave: When someone lets you into traffic or pulls aside on a narrow road to let you pass, a single raised hand is the expected acknowledgment. This is not optional in Caribbean driving culture – skipping the wave is genuinely rude. The wave costs nothing and keeps interactions pleasant.
Letting people in: On narrow streets and at junctions, local practice involves a degree of informal courtesy that goes beyond what traffic signs require. If someone is clearly waiting to pull out of a side street, letting them in (and receiving their wave) is standard. This reciprocity is how island driving works.
Pedestrian right-of-way: Official traffic rules give pedestrians right-of-way at marked crossings. In practice, pedestrians cross wherever seems reasonable to them, particularly in Marigot and on Boulevard de Grand Case. Slow down before any pedestrian area and expect to stop.
School hours: School start and end times (approximately 7:30-8 AM and 2-3 PM local time) create localized congestion near schools on both sides. If you are driving in the morning or afternoon, expect a brief slowdown near any school zone.
Animals on the road: Saint Martin has roaming goats and chickens, particularly in the less developed parts of the French side. They appear suddenly from vegetation at the road edge. Drive at reduced speed on narrow rural roads. The goats are not looking where they are going; you need to be.
Long-Term and Monthly Rentals
Most visitors rent for a week or less. But Saint Martin has a community of longer-term visitors – month-long winter escapes are common – and some agencies cater to them specifically.
Monthly rates: For a stay of 4+ weeks, ask agencies about monthly rates. Rates drop substantially from daily pricing:
| Vehicle | Weekly Rate (high season) | Estimated Monthly Rate | Monthly Savings vs. Weekly |
|---|---|---|---|
| Economy sedan | $290-420 | $700-900 | ~40-50% savings |
| Small SUV | $390-600 | $950-1,300 | ~40-50% savings |
| Jeep Wrangler | $550-780 | $1,200-1,600 | ~40-50% savings |
Monthly rentals are negotiated directly with agencies. Local agencies (Empress, Safari) are more flexible on monthly rates than international brands. The vehicle category, insurance, and included mileage should all be confirmed in writing for any rental over two weeks.
What changes for long-term rentals: Standard pickup documentation, insurance, and fuel policies remain the same. Some agencies do a mid-rental vehicle check for rentals over three weeks. The deposit remains blocked on your credit card for the duration. If the card has a spending limit close to the deposit amount, confirm with your bank that the hold can remain active for the rental period.
Driving at Night
Night driving on Saint Martin is generally safe but requires more caution than daylight driving.
Lighting: The main roads (ring road, Airport Road, the main Marigot-Grand Case road) have streetlights in populated areas. Secondary roads, beach access roads, and the French interior roads have minimal to no lighting. If you plan to visit a remote beach after sunset – for dinner at a beach restaurant, or for stargazing – drive slowly and use high beams when no oncoming traffic is present.
Speed bumps at night: Many speed bumps are unpainted or faintly painted. At night, they are essentially invisible until your headlights reveal them at close range. If you are on an unfamiliar road at night, assume speed bumps exist at every residential entrance, town boundary, and school zone. Drive at 20-30 km/h in any built-up area after dark.
Grand Case at night: The Boulevard de Grand Case is active with pedestrians in the evening dining hours. Park at the north lot and walk rather than driving the main strip – the combination of low lighting, pedestrians in the road, and narrow width makes slow speed essential.
Maho Beach at night: Plane spotters gather at Maho Beach at night to watch arrivals under lights. The access area is lit by the airport perimeter lighting. If you visit, be aware of the jet blast danger warnings – they apply equally after dark.
The Saint Martin Driving Experience in Practice
After driving the island thoroughly, a few honest observations that guidebooks tend to understate:
The island is genuinely tiny. This sounds obvious, but the experiential reality of it takes a day to absorb. You can drive from your hotel to the most remote beach in 25 minutes. You will never have a long drive. You will never worry about distance. The mental model of a typical road trip simply does not apply here – everything is a neighborhood drive, not a journey.
The variety is the point. In a single car trip of two hours, you can experience: a Dutch airport town with planes overhead, a Dutch beach, a quiet French residential area, the French capital with boulangeries, a French gourmet village, and a long white sand beach on the Atlantic coast. Two nations, four beach types, two currencies, two languages, and European-quality food – all within 40 kilometers of road.
Traffic and crowds are real. Saint Martin hosts over two million visitors per year in a destination of 87 square kilometers. On a peak cruise day in high season (January-February), the Dutch side roads are genuinely difficult. The French side is the escape – it absorbs overflow from the Dutch side without degrading noticeably. Knowing which days are heavy cruise days (Monday-Wednesday tend to be lighter, Friday-Sunday heavier in most high season periods) shapes where you drive on any given day.
The Suzuki Jimny is genuinely the right car. Every beach access road that seemed rough turned out to be exactly the sort of thing the Jimny handles without drama. The short wheelbase, the decent ground clearance, and the compact footprint combine into the ideal island vehicle. If you rent something larger, you will spend time wondering if it will fit on the road to Baie Rouge. If you rent an economy sedan, you will not attempt the road to Baie Rouge at all.
One tank of fuel, the whole week. This sounds like marketing copy until you actually do it. Our 5-day rental used less than half a tank (approximately 18 liters) despite visiting every major beach on the island and driving across the border multiple times daily. Fuel is a negligible budget item on Saint Martin.
Comparing Saint Martin to Other Caribbean Self-Drive Destinations
How does driving Saint Martin compare to other Caribbean islands?
| Factor | Saint Martin | Barbados | St. Lucia | Martinique | Anguilla |
|---|---|---|---|---|---|
| Drives on | Right | Left | Left | Right | Left |
| Island size | 87 sq km | 432 sq km | 616 sq km | 1,128 sq km | 91 sq km |
| Drive across island | 30 min | 30-40 min | 60+ min | 90+ min | 30 min |
| Road quality | Good-Fair | Good | Fair-Poor | Good | Good-Fair |
| Mountain roads | Moderate | None | Challenging | Moderate | None |
| Rental cost | $$ | $$ | \(-\)$ | $$ | $$$ |
| Two countries | Yes | No | No | No | No |
| Navigation complexity | Low | Low-Moderate | Moderate-High | Moderate | Low |
Saint Martin’s unique selling point from a driving perspective is the dual-country experience combined with the island’s small size. You get international variety without the navigation challenge of a larger island. The left-hand traffic on Barbados, St. Lucia, and Anguilla is a genuine adjustment for US and European drivers accustomed to the right; Saint Martin (right-hand traffic on both sides) eliminates that complication entirely.
Documents to Carry While Driving
A practical checklist of what to have in the car at all times:
| Document | Required? | Notes |
|---|---|---|
| Driver’s license | Yes | Original, not a copy |
| Passport | Not required while driving, but carry it | For identification if asked |
| Rental agreement | Yes | Shows insurance coverage |
| Emergency contact numbers | Yes | Rental agency + your accommodation |
| Insurance documents | Yes | CDW documentation from agency |
| Credit card used for rental | Keep accessible | For any additional charges or incidents |
The rental agency will give you an envelope with the agreement, insurance documents, and emergency contact. Keep it in the car. On an island this relaxed, you are unlikely to be asked for documentation while driving. But if there is an accident or a police stop, having everything organized is worth the minimal effort of keeping the envelope in the glove compartment.
