DVSA Motorway Rules and Smart Motorways

Question 1

What is the minimum engine size of a vehicle permitted to use a motorway in the UK?

Accepted Answer

There is no minimum engine size — the restriction is based on vehicle type and capability

Answer

There is no minimum engine size requirement for motorways. However, vehicles must be capable of maintaining a reasonable speed. Learner drivers, pedestrians, cyclists, horse riders, and certain slow-moving vehicles are prohibited from using motorways.

Question 2

On a smart motorway, what does a red X displayed above a lane mean?

Accepted Answer

The lane is closed — you must not drive in it

Answer

A red X above a lane on a smart motorway means the lane is closed. You must not drive in a lane showing a red X as there may be a stranded vehicle, debris, or people in the lane. Driving in a closed lane is an offence enforceable by camera.

Question 3

What should you do if you break down on a smart motorway with no hard shoulder?

Accepted Answer

Try to reach an emergency refuge area and call for help using the SOS phone

Answer

If you break down on a smart motorway without a hard shoulder, try to reach an emergency refuge area (ERA). If you cannot, move to the left-hand verge if possible, switch on your hazard lights, and call 999. Stay behind the crash barrier if there is one.

Question 4

When are you permitted to use the hard shoulder on a motorway for driving?

Accepted Answer

When directed to by overhead gantry signs on a smart motorway

Answer

On certain smart motorways (All Lane Running or controlled motorways), the hard shoulder may be opened as a running lane during busy periods. This is indicated by speed limit signs displayed above the hard shoulder on overhead gantries. You must only use it when signs indicate it is open.

Question 5

What is the purpose of emergency refuge areas (ERAs) on smart motorways?

Accepted Answer

To provide a safe place to stop in an emergency when there is no hard shoulder

Answer

Emergency refuge areas are orange-surfaced bays on smart motorways that provide a safe place to stop when the hard shoulder has been removed. They contain an SOS phone connected to Highways England. They are spaced approximately every 1.5 miles.
