Road guide
Driving in Guernsey
Guernsey has no road connection to Britain, France or another Channel Island. Confirm the sea crossing and vehicle first, then plan only the roads that the chosen vehicle can lawfully and safely use.
Book the vehicle ferry before calculating the island road stage
A private vehicle reaches Guernsey only on a carrier service that accepts it. The operator controls the route, check-in, vehicle dimensions, trailer or roof load and any live disruption; passenger-only travel does not transport the car.
Use St Peter Port harbour as the start or end of the local road leg. Recheck the sailing before leaving the mainland because a road estimate neither reserves deck space nor guarantees that weather permits the crossing.

Calculate your route
Enter a start and destination, plus up to three optional stops in travel order. The calculation opens on DrivingDirections.net with distance, estimated time, a route overview and turn-by-turn directions.
Verify visitor, licence, vehicle and insurance evidence separately
For Guernsey, bring the original licence for the vehicle category and match the registration and motor cover to written permission from the owner or hire company. Traveller admission and the carrier's check-in evidence remain separate controls.
Confirm the position for the licence's issuing jurisdiction and the length and purpose of stay before travel. A ferry accepting a vehicle does not prove that its driver, insurance or use is lawful on the island.
Use the States road-information map for the exact day
The States road-information map identifies closures, diversions, one-way controls and other traffic management. The summary report lists main-route disruption, while the map is needed for minor roads and the individual dates selected.
Search Guernsey's roadworks service by road name or postcode near departure, then let temporary island signs control the final approach. Traffic controls may be installed before work begins and remain after it finishes, so the shortest calculated line may not be available.
Match the vehicle to narrow lanes and local priority rules
Guernsey drives on the left and includes narrow lanes, filter-in-turn junctions and Ruettes Tranquilles. On those quiet lanes, vulnerable road users have priority and the signed low-speed environment is not a normal through-road shortcut.
Check width, length and turning space before accepting a minor-road route, especially with a camper, van or trailer. Slow early, use passing opportunities without blocking them and follow local signs rather than importing mainland assumptions.
Read the parking sign and set the correct clock
Many public spaces are disc zones. The sign sets the permitted stay and the driver displays a parking clock showing the arrival time; different locations and zones can impose different limits.
Set the clock only when parked, display it as instructed and return before the signed limit. The clock does not authorise a restricted bay, loading area, private space or a vehicle that does not fit wholly within the space.

End the car route before a car-free island transfer
A boat link from Guernsey to Sark, Herm or another island is a new transport stage, not continuous road geometry. Cars are not permitted on Sark or Herm for ordinary visitor travel.
Park lawfully in Guernsey, confirm the passenger sailing and plan the onward mode accepted at the destination. Do not send a driver toward a quay on the assumption that the same vehicle can continue.
Before driving in Guernsey
- Confirm the carrier, exact vehicle, dimensions, check-in and live sailing before the mainland road journey.
- Carry original driver, vehicle, insurance and permission evidence and verify each separately.
- Check the States map for the named road and read every local priority, width and parking sign.
- Confirm fuel or a compatible charger before the island leg, and retain enough range to return to a lawful stop if a road or ferry connection changes.
- Call 999 or 112 for an emergency and give the road name, parish, direction and nearest landmark.
