Speed Limits in Cayman Islands
Cayman sets speed limits road by road in subordinate legislation: Grand Cayman’s named sections range from 25 mph (40 km/h), the default on unlisted minor roads, to 50 mph on a few stretches, and school zones are 15 mph. There are no motorways.
Important: Posted signs always override default limits. Watch for temporary restrictions in construction zones, near schools, and in residential areas.
Speeding Fines and Penalties
Speeding fines in Cayman Islands 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 left side of the road. Overtake on the right. At roundabouts, traffic circulates clockwise: give way to vehicles already on the roundabout, which approach from your right, unless signs say otherwise.
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.
Drink-Driving Laws and Alcohol Limits
Cayman’s limit is 70 mg of alcohol per 100 ml of blood (0.07%), lowered from 0.10% in 2022. Penalties for drink-driving include heavy fines, licence confiscation, and potential imprisonment.
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
Winter tyres are not a consideration in Cayman Islands’s tropical climate; tyres in good condition are what matter.
The legal minimum tread depth is 1 mm, according to the Cayman Islands Traffic Regulations.
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.
