  2. 60 mphCevap
  3. C
    70 mph
  4. D
    40 mph

Cevap

60 mph
Under the UK Highway Code (Rule 124), the national speed limit for a car towing a trailer or caravan on a dual carriageway or motorway is 60 mph, provided no lower speed limit is signed. The additional load and stability factors require a 10 mph reduction compared to the 70 mph limit for solo passenger cars.

Adım Adım Çözüm

1
Identify the vehicle configuration and road classification.
Vehicle: Passenger car towing a trailer. Road type: Dual carriageway with no posted speed limit signs.
National speed limits under the Highway Code depend on both the road type and the specific vehicle category.
2
Recall the Highway Code national speed limit rules for towing vehicles.
Towing a trailer reduces the maximum allowed speed on dual carriageways and motorways from 70 mph to 60 mph (and on single carriageways from 60 mph to 50 mph).
Additional weight and articulated dynamics increase stopping distances and instability at higher speeds.
3
Select the correct speed limit for the scenario.
The maximum legal speed is 60 mph.
On an unrestricted dual carriageway, the national speed limit for a car towing a trailer is exactly 60 mph.
