Question

Difficulty: MediumTowing Rules, Speed Limits, and Lane Restrictions

When driving a car towing a trailer on a road where a 40 mph speed limit sign is displayed, the driver is legally required to travel at a maximum speed of 30 mph.

Answer: Answer

Answer

False. The maximum legal speed limit remains 40 mph.
The statement is false because specific posted speed limit signs indicate the maximum speed allowed for all standard vehicles, including cars towing trailers. The statutory 10 mph towing reduction applies only where national speed limits are in force.

Step-by-Step Solution

1
Identify the road category and the posted speed limit restriction.
The road displays a posted speed limit of 40 mph.
This establishes that a specific posted local limit is in effect rather than the national speed limit.
2
Apply the UK Highway Code speed limit rules for vehicles towing trailers.
Vehicles towing trailers are subject to reduced limits only on roads governed by the national speed limit (50 mph on single carriageways, 60 mph on dual carriageways and motorways).
Posted speed limits below national limits apply equally to cars towing trailers unless a lower specific limit is signed.
3
Determine the truth value of the statement.
The statement is false because the legal limit is 40 mph, not 30 mph.
Drivers towing a trailer are not legally required to deduct 10 mph from posted local speed limits.
