Introduction
Driving in French Guiana presents a unique blend of European road regulations and Amazonian adventure. As an overseas department of France, French Guiana follows French traffic laws, with vehicles driving on the right side of the road and steering wheels positioned on the left. The currency used is the Euro (€), and while major routes connecting Cayenne to Kourou and Saint-Laurent-du-Maroni are well-maintained, many secondary roads can be rough and unpaved. Tourists frequently rent cars to explore coastal towns and the Guiana Space Centre, though a 4x4 is highly recommended for venturing into the interior. Road signage is in French and follows European conventions. Fuel stations are concentrated along the coastal strip, becoming sparse as you move inland. Driving offers an unparalleled sense of freedom to discover this biodiverse region, but preparation is essential given the tropical climate, occasional heavy rains, and limited roadside assistance in remote areas.Is It Easy to Drive There?
Driving in French Guiana can be relatively straightforward along the developed coastal corridor, but presents significant challenges in the interior. The RN1 and RN2 highways connecting major towns are paved and generally in good condition. However, once you leave the main coastal routes, roads deteriorate rapidly, often becoming unpaved tracks that are impassable during the rainy season from December to July. Traffic in Cayenne can be congested during peak hours, and local driving styles may appear aggressive to visitors. Wildlife crossings, including tapirs and capybaras, are a genuine hazard on rural roads, especially at dusk and dawn. For tourists sticking to the main towns and the Space Centre, driving is manageable. For jungle expeditions, a guided tour or a robust 4x4 with high clearance is essential.Driving Side
In French Guiana, traffic keeps to the right side of the road, following standard French and European conventions. The steering wheel is positioned on the left side of the vehicle. Tourists arriving from countries that also drive on the right will find the transition seamless. For visitors from left-hand driving countries such as the United Kingdom, Australia, or Japan, extra vigilance is required at intersections and roundabouts until the right-side orientation becomes instinctive. Overtaking is always performed on the left. At unmarked intersections, priority is generally given to vehicles coming from the right, a classic French rule that surprises many foreign drivers.Speed Limits
| Road Type | Speed Limit | Notes |
|---|---|---|
| Urban Areas | 50 km/h | Reduced to 30 km/h in school zones and designated residential areas. |
| Rural Roads | 80 km/h | Many secondary roads are unpaved; adjust speed significantly in wet conditions. |
| Dual Carriageways | 110 km/h | Applies to divided highways. Lower limit of 100 km/h applies in rain. |
| Motorways (Autoroutes) | 130 km/h | There are no true autoroutes in French Guiana; the highest practical limits are on divided highways near Cayenne. Reduced to 110 km/h in wet weather. |
Seat Belt Laws
Seat belt use is mandatory for all occupants in the vehicle, both in the front and rear seats. The driver is legally responsible for ensuring that all passengers under the age of 18 are properly restrained. Failure to wear a seat belt can result in a fixed fine of €135 (approximately $146 USD), which may be reduced to €90 (approximately $97 USD) if paid promptly. Exemptions are extremely rare and typically require a valid medical certificate issued by a recognized French medical authority. In vehicles equipped with airbags, it is prohibited to place a rear-facing child seat in the front passenger seat unless the airbag has been specifically deactivated. The enforcement of seat belt laws has increased significantly in recent years as part of a broader French road safety initiative extended to all overseas departments.Child Seat Rules
Children under the age of 10 must be seated in an approved child restraint system appropriate for their weight and size. Infants up to 13 kg (approximately 29 lbs) require a rear-facing seat, typically used until around 12-15 months. Children weighing between 9 and 18 kg (approximately 20-40 lbs) must use a forward-facing child seat with a harness. Booster seats are mandatory for children under 10 years or under 135 cm in height, whichever comes first. The ISOFIX anchorage system is standard in most modern rental vehicles and is highly recommended for secure installation. A child may only ride in the front seat if the rear seats are already fully occupied by other children under 10, and only with the appropriate restraint for their size. Taxis are generally exempt from child seat requirements, but it is advisable to arrange one in advance if traveling with young children.Drink Driving Laws
French Guiana enforces a strict blood alcohol concentration limit of 0.05% for experienced drivers, equivalent to 0.5 grams per liter of blood. For new drivers holding a probationary license for the first three years, the limit is reduced to 0.02%. The penalties for exceeding these limits are severe. A BAC between 0.05% and 0.08% results in a flat fine of €135 (approximately $146 USD) and a possible six-point deduction from the driving license. A BAC exceeding 0.08% is a criminal offense that can lead to a fine of up to €4,500 (approximately $4,860 USD), immediate license suspension, vehicle immobilization, and a potential prison sentence of up to two years. Random roadside breath tests are frequently conducted by the Gendarmerie, particularly on weekend evenings and near popular nightlife spots in Cayenne and Kourou.Mobile Phone Rules
The use of a handheld mobile phone while driving is strictly forbidden in French Guiana. This includes holding the phone to talk, text, browse the internet, or adjust GPS settings while the vehicle is in motion. Hands-free devices such as Bluetooth earpieces and integrated car systems are permitted, provided they do not impair the driver's attention. The fine for using a handheld phone is a fixed penalty of €135 (approximately $146 USD), accompanied by a deduction of three points from the driving license. If a driver is caught simultaneously committing another moving violation, such as speeding or failing to maintain lane discipline, the license can be suspended immediately. Mounting a phone on a dashboard holder for GPS navigation is legal as long as the device is not physically handled while driving.Required Documents
When driving in French Guiana, you are required to carry the following documents at all times: a valid passport or national identity card for EU citizens, a full and valid driving license, an International Driving Permit if your license is not in French or from a non-EU/EEA country, the vehicle registration document (carte grise), a valid certificate of motor insurance (carte verte), and your rental contract if driving a rental vehicle. It is also mandatory to carry a reflective warning triangle and a high-visibility safety vest inside the passenger compartment, not in the trunk, for use in the event of a breakdown. The absence of these documents can result in on-the-spot fines.International Driving Permit (IDP)
An International Driving Permit is required for visitors whose national driving license is not written in French or is not issued by a European Union or European Economic Area member state. Travelers from the United States, Canada, Australia, and the United Kingdom must carry an IDP alongside their valid domestic license, as their licenses are not in French and fall outside the reciprocal agreements. The IDP serves as a certified translation of your existing license and is not a standalone document; you must always carry your original license with it. An IDP can be obtained in your home country before departure through authorized automobile associations. Driving without an IDP when one is required can result in a fine of up to €750 (approximately $810 USD) and potential vehicle confiscation.Road Signs
Road signs in French Guiana follow the standard French system. Regulatory signs are typically circular with a red border on a white background, such as the red-and-white stop sign reading 'STOP' or the yield sign with a red inverted triangle. Warning signs are triangular with a red border on a white background, signaling hazards like bends, wild animals, or pedestrian crossings. Blue square signs indicate motorway-like directions, while green signs point to major destinations. A common sign to be aware of is the 'Priorité à droite' warning, a yellow diamond with a black cross, which indicates that the French right-hand priority rule is suspended at that intersection; otherwise, you must yield to vehicles joining from the right. School zone signs feature the silhouette of two children and require reduced speed.Toll Roads
French Guiana does not have a network of toll roads. All roads, including the primary coastal highways RN1 and RN2 that connect Cayenne to Kourou, Sinnamary, and Saint-Laurent-du-Maroni, are toll-free. There are no electronic toll collection systems, vignettes, or toll plazas anywhere in the territory. The absence of tolls is a welcome relief for tourists planning road trips along the coast. The funding for road infrastructure and maintenance comes directly from the French central government and local territorial collectivity budgets. This makes driving a relatively affordable way to explore the department, with fuel being the primary ongoing cost of operating a vehicle.Fuel Stations
Fuel stations in French Guiana are primarily located in urban centers and along the main coastal highways. The most common fuel types available are unleaded petrol (Sans Plomb 95 and 98) and diesel (Gazole). LPG and CNG are not widely available for public use. Electric vehicle charging infrastructure is in its infancy, with a handful of charging points located in Cayenne, primarily at shopping centers and hotels, but coverage is extremely limited outside the capital. Most fuel stations operate from early morning until evening, typically closing by 7:00 PM or 8:00 PM, with very few operating 24 hours. As of mid-2026, the average price for diesel is approximately €1.95 per liter (approximately $2.11 USD per liter), and unleaded petrol is around €2.05 per liter (approximately $2.22 USD per liter), making French Guiana one of the more expensive places in South America for fuel.Parking Rules
Parking regulations in French Guiana are enforced in urban areas, particularly in central Cayenne. Paid parking zones, marked with 'Payant' signs and blue markings, operate during business hours, typically from 9:00 AM to 12:00 PM and 3:00 PM to 6:00 PM, Monday to Saturday. Parking fees are generally around €1.50 to €2.50 per hour (approximately $1.62 to $2.70 USD). Payment is made at nearby parking meters (horodateurs) that issue a ticket to be displayed on the dashboard. In commercial areas and supermarkets, parking is usually free. Illegal parking, such as on a sidewalk or in a disabled bay without a valid badge, incurs a fine of €35 (approximately $38 USD), rising to €135 (approximately $146 USD) for more serious obstructions. Wheel clamping and towing are enforced in central Cayenne. Always check for local signage and never assume parking is free.Roundabout Rules
Roundabouts in French Guiana follow standard French rules. Vehicles already circulating inside the roundabout have priority over vehicles entering, which is indicated by the 'Vous n'avez pas la priorité' or yield signs at all entrances. When approaching a roundabout, you must signal your intentions: signal left if you intend to take an exit that is more than 180 degrees around or essentially turning back, and signal right just after passing the exit before the one you wish to take. Always check your mirrors and blind spots for cyclists and scooters, which are common in urban areas. Do not change lanes within a multi-lane roundabout unless it is safe to do so. The central island often features large sculptures or public art, making them distinctive local landmarks.Winter Driving
French Guiana experiences a tropical climate with high temperatures and humidity year-round, so winter driving conditions involving snow or ice are entirely absent. There are no requirements for snow tyres, winter chains, or specialized cold-weather equipment at any time of the year. However, the rainy season from December to July brings torrential downpours that can cause flash flooding, reduced visibility, and muddy or washed-out road surfaces, especially on unpaved interior roads. Drivers during this period should ensure their vehicle has good quality all-season tyres with adequate tread depth to handle wet and muddy conditions. It is also wise to carry a basic emergency kit with water, a flashlight, and a first-aid kit, as breakdown services are sparse in remote areas.Low Emission Zones
Currently, there are no permanent low-emission zones (Zones à Faibles Émissions or ZFE) established in French Guiana. The Crit'Air vignette system, which restricts older, more polluting vehicles from entering designated areas in mainland French cities, is not enforced in Cayenne, Kourou, or any other municipality in the territory. However, as part of France's broader environmental strategy, discussions about implementing such zones in French overseas departments are ongoing. For the time being, all vehicles, regardless of their emissions class or age, can freely access all urban areas. Drivers of older diesel vehicles should still be aware that regulations can change, and it is advisable to check local government announcements before travel.Traffic Fines

| Running a Red Light | €135 | $146 | 4 points deducted |
| Illegal Parking | €35 to €135 | $38 to $146 | Vehicle may be towed |
Driving Tips for Tourists
1. Always carry your passport, driving license, and IDP while driving; police checkpoints are common on major routes. 2. A high-visibility vest must be kept inside the passenger compartment, not in the trunk, and worn before exiting the vehicle in a breakdown. 3. Beware of the 'Priorité à droite' rule at unsigned intersections—yield to traffic approaching from the right unless signs indicate otherwise. 4. Do not drive on the beaches; this is strictly prohibited and fines are heavy. 5. Fill up your fuel tank whenever you see a station, as they are sparse inland and may close early. 6. Avoid driving at night outside of urban centers due to unlit roads and wildlife crossing hazards. 7. In heavy tropical rain, pull over safely and wait for visibility to improve; flash floods can occur rapidly on interior roads. 8. Roundabouts are priority-to-the-left, meaning vehicles already on the roundabout have the right of way. 9. The road between Cayenne and the Space Centre in Kourou is excellent but heavily policed for speed. 10. If involved in an accident, do not move the vehicles and fill out a European Accident Statement form, which rental companies provide.Renting a Car
Renting a car in French Guiana is the most practical way to explore the coastal region and major attractions like the Guiana Space Centre. The minimum rental age is typically 21, and drivers under 25 may incur a young driver surcharge of approximately €30 to €50 per day (approximately $32 to $54 USD). A major credit card is required for the security deposit, and debit cards are often not accepted for the hold. Basic insurance with a high deductible is mandatory, but a comprehensive excess reduction policy is highly recommended given the risk of road debris and flooding damage. Fuel policies are usually full-to-full. International rental agencies such as Avis, Europcar, and Hertz operate at Félix Éboué Airport in Cayenne, alongside local providers who may offer better rates for 4x4 vehicles. One-way rentals between the airport and city offices are available but inter-city drop-offs are rare. An economy car rents for around €60 to €80 per day (approximately $65 to $86 USD), while a robust 4x4 costs upwards of €120 per day (approximately $130 USD). Book well in advance if traveling during the Ariane rocket launch windows, as demand spikes.Frequently Asked Questions
