Since 2018, learner drivers in the UK can take lessons on motorways with an approved driving instructor in a car with dual controls. Motorways have their own rules, signs and behaviours — and getting comfortable with them before you pass makes you a much safer new driver.
1Motorways vs dual carriageways
A motorway is a higher-grade road distinguished by blue signs (not green). Key differences from dual carriageways:
• Minimum speed expectations — you must be capable of sustaining at least 50–60 mph. • No pedestrians, cyclists, motorcycles under 50cc, or horse riders allowed. • Hard shoulder (or emergency refuge area on smart motorways) along the edge. • Maximum speed limit: 70 mph. • Learner drivers CAN use motorways with an ADI in a dual-control car.
Until 2018, learner drivers were banned from motorways entirely. Now you can practise with your instructor — and it's highly recommended before you pass.
2Joining the motorway
Joining a motorway follows the same slip road principle as a dual carriageway, but at higher speeds and with faster-moving traffic:
1. Build up speed on the slip road to match motorway traffic (60–70 mph). 2. Check your right mirror and blind spot early and repeatedly. 3. Signal right and look for a gap in the left lane. 4. Merge smoothly — traffic already on the motorway has priority. 5. Once on the motorway, accelerate to a safe, legal cruising speed.
Motorway traffic is faster and less forgiving of slow or hesitant merging — confidence matters here.
💡 Tips
- •Use the full length of the slip road — don't try to merge too early.
- •If no gap appears, you may need to slow or stop at the end of the slip — do this safely, not at the last second.
3Lane discipline and speed
The same rules as dual carriageways apply — the left lane is the driving lane, right lanes are for overtaking only.
• Always return to the left lane after overtaking. • Never overtake on the left (undertaking) — it's illegal except in queuing traffic. • The speed limit is 70 mph unless indicated by signs (variable speed limits on smart motorways). • Keep well back from the vehicle in front — at 70 mph use at least a 4-second gap in good conditions.
4Smart motorways
Smart motorways use technology to manage traffic flow. There are three types:
• Variable speed limit — overhead gantries display speed limits that change with conditions. These are legally enforceable. • Dynamic hard shoulder — the hard shoulder can be opened as a running lane at busy times. Check overhead signs. • All-lane running — there is no permanent hard shoulder. Emergency Refuge Areas (ERAs) are provided roughly every mile.
If your car breaks down on an all-lane running motorway, try to reach an ERA. If you cannot, put on hazard lights and exit the vehicle via the left door if it's safe to do so.
Speed limits shown on smart motorway gantries are mandatory — they are enforced by cameras and carry the same penalties as any other speed limit.
💡 Tips
- •If a red X appears on the gantry above your lane, you must not drive in that lane — it may indicate an obstruction or breakdown ahead.
5Breaking down on a motorway
Breaking down on a motorway is frightening but manageable:
1. Move to the left-hand hard shoulder (or ERA on smart motorways) as soon as possible. 2. Switch on your hazard warning lights. 3. If possible, exit via the left door and stand on the embankment or behind the barrier — away from traffic. 4. Do not stand behind your car. 5. Call for recovery — the emergency phones on the hard shoulder connect directly to Highways England. 6. If your car stops in a live lane (smart motorway), stay in the car with your seatbelt on and call 999.
💡 Tips
- •Before long journeys, always check tyre pressures, fuel level and basic fluid levels.
- •Carry a high-visibility vest, warning triangle and phone charger in your car.
