Question

Difficulty: EasySpeed Limits on Motorways

On a smart motorway, a speed limit displayed inside a red circle on an overhead gantry is legally mandatory.

Answer: Answer

Answer

True
In the UK Highway Code, signs with a red ring give orders. When a variable speed limit is shown inside a red ring on a motorway gantry, it is legally enforceable and sets a mandatory maximum speed.

Step-by-Step Solution

1
Identify the sign type and border design
The speed limit is enclosed within a circular sign with a red border on an active gantry display.
Circular signs with red rings convey mandatory orders and legal restrictions under the UK Highway Code.
2
Differentiate between mandatory and advisory motorway signals
Signals in red rings are legally binding, whereas amber flashing matrix signs indicate advisory speeds or warnings.
Variable speed limits displayed within red circles must be adhered to until signs indicate otherwise or the national speed limit sign appears.
