Joining, lane discipline, smart motorways, red X signals and breakdowns — the Motorway Rules topic and its Highway Code rules.
What does “Motorway Rules” cover?
The motorway-specific rulebook: joining from slip roads, keeping left unless overtaking, speed limits, smart motorway signals and emergency areas, hard shoulder rules, and what to do when you break down at 70 mph.
Which Highway Code rules should I revise?
Rules 253 (who’s prohibited), 258 and 261 (signals and red X), 259 (joining), 264 (keep left), 269–270 (hard shoulder), and 275–278 (breakdowns: leave by the left doors and wait behind the barrier, away from traffic).

What does a red X above a motorway lane mean?
The lane is closed — you must not drive in it. It's enforced by camera, and there may be a stopped vehicle or people ahead.
Can learner drivers use motorways?
Yes, since 2018 — but only with an approved driving instructor in a car fitted with dual controls.
