Difficulty: EasySpeed Limits on Motorways

Unless signs show a lower limit, what is the national speed limit on a motorway for a car towing a trailer?

  1. A
    50 mph
  2. 60 mphAnswer
  3. C
    70 mph
  4. D
    80 mph

Answer

60 mph
Under the UK Highway Code, the national speed limit on motorways is 70 mph for standard cars and motorcycles. However, any vehicle towing a trailer or caravan is legally limited to a maximum speed of 60 mph on motorways and dual carriageways, provided no lower speed limit is displayed.

Step-by-Step Solution

1
Identify the vehicle category and the road type
The vehicle is a car towing a trailer, and the road is a motorway with standard national speed limits applying.
National speed limits under the UK Highway Code vary based on vehicle classification and whether a trailer is being towed.
2
Apply the specific UK speed limit rule for towing vehicles
Cars towing trailers or caravans are restricted to a maximum speed of 60 mph on both dual carriageways and motorways.
A reduced speed limit applies because towing increases vehicle weight, stopping distances, and the risk of instability at high speeds.
