Zorluk: ZorSpeed Limits

Under the Highway Code, national speed limits vary according to vehicle configuration, trailer attachments, and road classifications. Match each specific driving situation described below to its statutory maximum speed limit where no specific numerical signs are present.

  • A solo passenger car driving along an urban road equipped with a regular system of street lighting30 mph
  • A passenger car towing a caravan along a rural single carriageway road50 mph
  • A passenger car towing a lightweight trailer on a three-lane motorway60 mph
  • A solo car-derived van not exceeding 2 tonnes maximum laden weight on an unrestricted dual carriageway70 mph

Cevap

Urban street with street lighting matches 30 mph; Car towing caravan on single carriageway matches 50 mph; Car towing trailer on motorway matches 60 mph; Car-derived van (up to 2 tonnes) on dual carriageway matches 70 mph.
Each scenario directly corresponds to the statutory Highway Code rules: presence of street lighting implies 30 mph; towing on single carriageways is capped at 50 mph; towing on motorways is capped at 60 mph; and car-derived vans under 2 tonnes share the 70 mph passenger car limit on dual carriageways.

Adım Adım Çözüm

1
Identify the default rule for roads with street lighting
A continuous system of street lighting defines a built-up area with a default limit of 30 mph.
This is the statutory default limit across the UK when no higher or lower limit is posted.
2
Apply the speed limit reduction for towing combinations on single carriageways
The national speed limit for cars towing trailers on single carriageways is 50 mph (10 mph lower than solo cars).
Towing increases braking distance and stability risks, requiring a mandatory lower limit.
3
Determine the speed restriction for towing vehicles on high-speed dual carriageways and motorways
Cars towing trailers or caravans are limited to 60 mph on dual carriageways and motorways.
The national speed limit for towing vehicles on motorways is capped at 60 mph rather than the 70 mph allowed for solo cars.
4
Identify the vehicle category rules for car-derived vans up to 2 tonnes maximum laden weight
A car-derived van under 2 tonnes maximum laden weight is permitted to travel up to 70 mph on dual carriageways.
Unlike larger commercial goods vans, car-derived vans weighing up to 2 tonnes follow standard passenger car national speed limits.
