Question

Difficulty: MediumSpeed Limits

Under the UK Highway Code, national speed limits vary depending on the vehicle configuration and the road type being used. Match each driving scenario to its correct maximum legal speed limit where no specific signs indicate otherwise.

  • A solo passenger car driving on a road with regular street lighting and no speed limit signs30 mph
  • A car towing a trailer on an unposted single carriageway50 mph
  • A car towing a caravan on an unposted dual carriageway60 mph
  • A solo passenger car on an unposted motorway70 mph

Answer

A solo car on a street-lit road matches 30 mph; a car towing a trailer on a single carriageway matches 50 mph; a car towing a caravan on a dual carriageway matches 60 mph; a solo car on a motorway matches 70 mph.
Each pairing reflects the statutory Highway Code speed limit: street-lit roads without signage default to 30 mph; cars towing trailers on single carriageways are limited to 50 mph; cars towing caravans on dual carriageways are limited to 60 mph; and solo cars on motorways are permitted up to 70 mph.

Step-by-Step Solution

1
Determine the speed limit for roads with street lighting
30 mph applies to roads with regular street lighting unless signed otherwise.
The Highway Code establishes 30 mph as the standard limit in built-up areas with street lights.
2
Determine the speed limit for a car towing a trailer on a single carriageway
50 mph applies to vehicles towing trailers on single carriageways.
Towing configurations reduce the national single carriageway limit from 60 mph to 50 mph.
3
Determine the speed limit for a car towing a caravan on a dual carriageway
60 mph applies to vehicles towing caravans on dual carriageways.
Towing configurations reduce the national dual carriageway limit from 70 mph to 60 mph.
4
Determine the speed limit for a solo car on a motorway
70 mph applies to solo passenger cars on motorways.
70 mph is the default national speed limit for cars and motorcycles on motorways.
