Difficulty: MediumSmart Motorways and Active Traffic Management

During peak traffic hours on an active traffic management section of motorway, an overhead gantry displays a speed limit of 60 mph enclosed in a red circle directly above the hard shoulder. What does this signal require you to do?

  1. A
    Remain in the central lanes and avoid the hard shoulder unless your vehicle experiences an emergency breakdown
  2. Drive in the hard shoulder as a normal running lane while staying at or below the displayed speed limitAnswer
  3. C
    Use the hard shoulder exclusively as a designated lane to undertake slower queuing traffic
  4. D
    Treat the displayed number as an advisory recommendation and proceed at up to the national speed limit

Answer

Drive in the hard shoulder as a normal running lane while staying at or below the displayed speed limit
On smart motorways with Active Traffic Management (dynamic hard shoulders), a speed limit displayed inside a red circle above the hard shoulder means it is open to all traffic as an active running lane. Drivers must use normal lane discipline and must not exceed the mandatory speed limit shown.

Step-by-Step Solution

1
Identify the gantry signal shown above the hard shoulder
Recognise that a speed limit in a red circle over the hard shoulder opens it as an active running lane
On smart motorways with dynamic hard shoulders, a displayed speed limit indicates the lane is operational for standard driving.
2
Determine the legal status of the speed limit shown
Identify that a circular red ring signifies a mandatory legal maximum speed limit
Circular signs with red borders give mandatory instructions that drivers must legally obey.
