While travelling on an unlit rural road with a single carriageway, you pass a national speed limit sign (a circular white sign with a single black diagonal stripe). If your car is towing a trailer, what is your maximum legal speed limit?

  1. A
    40 mph
  2. 50 mphCevap
  3. C
    60 mph
  4. D
    70 mph

Cevap

50 mph is the maximum legal speed limit for a car towing a trailer on a single carriageway road.
According to the UK Highway Code, the national speed limit on a single carriageway is 60 mph for solo cars, but it is restricted to 50 mph for any car towing a trailer or caravan.

Adım Adım Çözüm

1
Identify the road classification and the vehicle combination from the scenario.
The road is a single carriageway subject to the national speed limit, and the vehicle is a car towing a trailer.
Statutory speed limits in the UK depend on both the road type and the vehicle category.
2
Apply the statutory speed limit reduction for towing combinations.
While solo passenger cars may travel up to 60 mph on a single carriageway, towing any trailer or caravan reduces the limit by 10 mph to 50 mph.
The increased momentum, stopping distance, and instability risks associated with towing require a lower speed threshold.
