Question

Difficulty: HardMotorway Signals and Reflective Studs

On UK motorways, a speed limit displayed on an overhead gantry inside a red circle is legally mandatory, whereas a speed limit shown alongside flashing amber lights is an advisory recommendation.

Answer: Answer

Answer

True (speed limits inside a red circle are legally mandatory, while speeds shown with flashing amber lights are advisory)
The statement correctly reflects UK motorway regulations: variable speed limits enclosed in a red circle are mandatory and legally enforceable, whereas numeric speeds displayed alongside flashing amber lights serve as advisory guidance to warn of hazards ahead.

Step-by-Step Solution

1
Examine the regulatory status of motorway signals displaying a speed limit inside a red circle.
Identify that signs enclosed in a red circle convey mandatory legal instructions under UK traffic law and the Highway Code.
Variable speed limits displayed within red rings on smart motorways and gantries are legally binding and subject to automatic camera enforcement.
2
Examine the meaning of motorway signals accompanied by flashing amber lights.
Identify that flashing amber lights indicate a hazard ahead and display advisory information.
Highway Code Rule 257 specifies that flashing amber lights warn of hazards and recommend a safe speed, but they do not create a statutory mandatory limit.
3
Compare both parts of the statement against UK motorway rules to evaluate its truth value.
Confirm that the statement accurately contrasts mandatory speed limits with advisory hazard warnings.
Both clauses correctly state official UK driving regulations regarding motorway matrix signals.
