Level Crossings, Tram Lines and Box Junctions — Theory Test Guide
Three high-risk features that generate reliable test questions. Here's what to do at each and the specific rules to remember.
Level crossings
A level crossing is where a road crosses a railway. The overwhelming rule: never start to cross unless the road on the other side is clear. If you break down on one, get everyone out of the vehicle and away from the crossing, then use the phone if there is one.
- Amber light + audible warning: stop unless already crossing.
- Red lights flashing: stop and wait, even if no train is visible.
- Half-barrier: never zig-zag around it, even if it's stuck down.
- Open crossing (no barriers, no lights): look both ways, listen, and cross only if clear.
Tram lines
Trams are quiet, fast and cannot swerve. Never drive or park on tram rails, and give way to trams at every opportunity. Diamond-shaped signs are for tram drivers, not you — you can ignore them.
- Watch for cyclists whose wheels can get caught in tram rails.
- White light signals: for trams, not car drivers.
- Never overtake a tram on the right unless it is at a specifically-marked stop.
Box junctions
Yellow crisscross lines painted on the road. You must NOT enter the box unless your exit road is clear. The one exception: you can wait in the box if you're turning right and are only stopped by oncoming traffic or other vehicles waiting to turn right.
Why these come up so often
All three sit in the DVSA's 'safety and your vehicle' plus 'rules of the road' categories, which together account for around 20% of theory test questions. A single hour of focused revision on these three topics is high-yield.
