UK Highway Code — Plain-English Summary for Learner Drivers
The official Highway Code is 154 pages. The parts an examiner actually tests you on fit on one page. Here's that page — the priorities, speed limits, roundabout lanes and signalling rules you must know before your UK practical driving test.
Speed limits
| Road type | Car | Car + trailer |
|---|---|---|
| Built-up area (street-lit) | 30 mph | 30 mph |
| Single carriageway | 60 mph | 50 mph |
| Dual carriageway | 70 mph | 60 mph |
| Motorway | 70 mph | 60 mph |
Priorities at junctions
- Give way to traffic already on the major road.
- At a roundabout, give way to traffic from your right.
- At a T-junction, emerging traffic gives way.
- Pedestrians crossing or waiting to cross at the junction you're turning into have priority (Highway Code rule H2, updated 2022).
Roundabout lane choice
- First exit (usually left): approach in the left lane, signal left.
- Any exit up to 12 o'clock: left lane, no signal on approach, signal left before your exit.
- Any exit past 12 o'clock: right lane, signal right on approach, switch to left before exiting.
See worked examples at driving test manoeuvres.
Signals — when and for how long
- Signal in good time — around 3 seconds before any manoeuvre.
- Cancel the signal as soon as you've completed the move.
- Never signal left too early when passing a parked car — it can confuse traffic behind.
Stopping distances (dry conditions)
| Speed | Thinking distance | Braking distance | Total |
|---|---|---|---|
| 20 mph | 6 m | 6 m | 12 m |
| 30 mph | 9 m | 14 m | 23 m |
| 40 mph | 12 m | 24 m | 36 m |
| 50 mph | 15 m | 38 m | 53 m |
| 60 mph | 18 m | 55 m | 73 m |
| 70 mph | 21 m | 75 m | 96 m |
Double these in wet weather. On ice, multiply by ten.
Motorways — for when you get your full licence
- Lane 1 is the default. Move out only to overtake, then move back.
- Use the hard shoulder only in an emergency (unless signed otherwise on smart motorways).
- Minimum speed: there isn't one, but drive so you don't hold up faster traffic.
Pedestrians, cyclists and vulnerable road users
- Always give priority to anyone crossing or waiting to cross at the side road you're turning into.
- Leave at least 1.5 m when overtaking a cyclist at 30 mph or under; 2 m above 30 mph.
- Slow right down around horses and pass wide.
