Key takeaways
- A red X over a lane means it's closed — never drive in it.
- Speed limits shown in a red circle on overhead signs are legal limits.
- Emergency areas are marked with orange surfaces and blue signs with an orange SOS symbol.
- Learners can have motorway lessons with an approved instructor in a dual-controlled car.
What makes a motorway "smart"
Smart motorways use technology to manage traffic. Some use the hard shoulder as a live lane permanently or at busy times. Several stretches of motorway around Greater Manchester — including sections of the M60, M62 and M6 — work this way.
Signs you must obey
- Red X: the lane is closed, often because of a breakdown or workers ahead. Move out of it safely. Driving in a red X lane is an offence.
- Speed in a red circle: a legal limit, often lowered for congestion or incidents. Cameras may enforce it.
- Solid white line: marks the hard shoulder where it isn't a live lane. Don't use it unless signs say so.
If you break down
- Try to leave at the next junction or reach an emergency area (orange surface, blue sign with an orange SOS).
- If you can't, move as far left as possible, switch on hazard lights and, if safe, get out on the left and go behind a barrier.
- Call 999 if you're stopped in a live lane.
