Motorway questions are some of the easiest marks in the Theory Test — if you understand a handful of core rules.
Most learners lose marks because they carry city-driving habits onto motorways. This guide fixes that.
Lane discipline: the rule most people think they know
The principle is simple:
Keep left unless overtaking.
That applies even when traffic is light. The right lanes are not “fast lanes”; they’re overtaking lanes.
Common mistake
Sitting in the middle lane because it feels “safer”. That’s poor discipline and can cause congestion.
Following distance: two seconds (and more when needed)
Standard rule:
- 2-second gap in good conditions
- increase the gap in wet/poor visibility
- increase further if towing or driving a larger vehicle
DVSA loves questions about how the gap changes with rain, fog, and spray.
Overtaking: when not to do it
Don’t overtake when:
- you’d need to exceed the speed limit
- the vehicle ahead is already overtaking
- traffic is heavy and you’re weaving lanes
Stay smooth. Motorways reward predictability.
Breakdown rules: what to do if you must stop
The safest place to stop is:
- a service area
- a parking place designed for stopping
If you must stop in an emergency, follow the correct steps (as taught in Highway Code guidance).
Key ideas DVSA tests:
- get yourself and passengers safe
- warn other road users
- use the correct exit strategy
Smart motorways: understand the signs
You must know the meaning of:
- lane closure signals (red X)
- variable speed limits
- warning signs for incidents
The red X is not optional
A red X means the lane is closed. You must not drive in it.
Joining the motorway: build speed and match traffic
Use the slip road to build speed and fit into a gap.
Don’t stop at the end of the slip road unless absolutely necessary.
Driving in poor conditions
In fog:
- use fog lights correctly
- reduce speed
- increase distance
- be prepared for sudden hazards
Quick motorway checklist for the test
If you remember these, you’ll pick up easy marks:
- keep left unless overtaking
- use mirrors before signalling and changing lanes
- two-second rule (more in wet)
- understand variable speed limits
- obey lane closure signals
Motorway rules aren’t complicated — they’re consistent. Learn the consistency and you’ll score well.
