The national speed limit for cars and motorcycles on a motorway is 70 mph (112 km/h), regardless of the lane you’re in. However, always adhere to any signs indicating a lower speed limit, as they may be in place for safety reasons or due to specific road conditions.
A vehicle towing a trailer is subject to specific regulations on motorways:
- The speed limit for a vehicle towing a trailer is typically lower than that for cars and motorcycles, usually set at 60 mph (96 km/h).
- When driving on a three-lane motorway, a vehicle towing a trailer is generally not permitted to use the right-hand lane unless there are lane closures or specific circumstances warranting its use.
In Northern Ireland, vehicles towing trailers are advised not to use the right-hand lane of a three-lane motorway.
When encountering traffic slowdowns or sudden stops, you can use hazard lights to alert vehicles behind you. However, remember to turn them off as soon as a queue forms behind your vehicle.
Approaching roadworks requires extra caution. Lower speed limits are typically enforced, especially in contraflow systems. Always obey posted speed limits and maintain a safe distance from the vehicle ahead.
