100 km/h on Comoros Motorways, 50 km/h in Town (2026)

Comoros sets its motorway speed cap at 100 km/h, drops to 80 km/h on rural roads and to 50 km/h in built-up areas — a wider urban-to-motorway gap than many neighbouring islands. Traffic keeps to the right. Police answer on 117 and the fire service on 113, and there is no national ambulance line, which matters given the limited cellular coverage on some routes.

Speed limits are 50 km/h in urban areas, 80 km/h on rural roads, and 100 km/h on motorways.

Speeding fines in Comoros vary based on how much you exceed the posted limit. Fines increase sharply for higher violations and may include licence points or driving bans for serious offences.

Traffic Rules and Regulations

Drive on the right side of the road. Overtake on the left. At roundabouts, enter counter-clockwise and yield to traffic already circulating.

Seatbelts are mandatory for all occupants. Children must use appropriate restraint systems based on their age and height.

Using a hand-held phone while driving is prohibited. Hands-free systems are permitted.

Use headlights in poor visibility, tunnels, and at night. Some areas require headlights at all times.

At unmarked intersections, traffic from the right generally has priority unless signs indicate otherwise.

Drink-Driving Laws and Alcohol Limits

Drink-driving is illegal in Comoros. Check the current legal blood alcohol limit with local authorities before driving. As a rule, do not drink any alcohol if you plan to drive.

The safest approach is to not drink at all if you will be driving. Alcohol affects reaction time and judgement regardless of the legal limit.

Tyre Requirements and Regulations

Due to Comoros’s tropical climate, winter tyres are not required. Standard tyres suitable for wet and dry conditions are appropriate year-round.

The legal minimum tread depth is 1.6 mm.

Studded tyres are prohibited in Comoros.

Driving License Requirements

Always carry your original driving licence — photocopies are not accepted.

Parking and Fuel

Parking rules vary by city. Look for designated parking areas and always check signs for time limits and payment requirements.

Most fuel stations accept major credit and debit cards. In rural areas, keep your tank above half — stations may be far apart.

Seasonal Driving Conditions

Comoros has a diverse terrain from coastal to highland. The main driving hazard is heavy rainfall — roads can flood quickly and visibility drops sharply during downpours. Reduce speed in rain and avoid crossing flooded sections. Road surfaces may deteriorate during the wet season.
