Motorway Driving for the First Time: 70 mph UK Guide

#What legal and practical setup do you need before joining a UK motorway?

Since June 2018, learner drivers in the UK have been allowed on motorways, but only with an approved driving instructor (ADI) in a dual-control car. If you are now a full licence holder, that restriction is gone, but the principles your ADI taught you still apply. Read the main pass guide and the Pass Plus guide before your first solo motorway drive, because Pass Plus exists for exactly this transition and many insurers will discount your premium for completing it.

Practical setup matters more than people realise. Check your tyres for pressure and tread before you set off. A blowout at 70 mph is a different problem to a slow puncture at 30 mph. Top up your screenwash. Make sure your fuel range comfortably covers your trip plus a 30 mile buffer, because running out of fuel on a motorway is treated as a careless driving offence and can get you points.

#How do you join a UK motorway safely for the first time?

The slip road is where new drivers most often get into trouble. The job is to match the speed of traffic in lane one before you merge, not after. Use the full length of the slip road. Build to roughly 60 to 65 mph if traffic is flowing freely, then check your right-hand mirror, signal right, check your blind spot, and ease across in a smooth arc. If a lorry is in lane one and you cannot get up to speed in time, you may need to brake on the slip road and merge behind it. That is fine. What you must not do is stop at the end of the slip road. Stopping creates a hazard for everyone behind you.

Once you are on, hold lane one until you have settled. There is no rule that says you must move out. Lane one is the default, lanes two and three are for overtaking, and you should return to a less congested lane as soon as your overtake is done.

#What do UK smart motorway signs mean?

A meaningful chunk of the UK network is now smart motorway. There are three types you might encounter, and the differences matter.

• All Lane Running: the hard shoulder is a permanent live lane. Look for the gantry signs above each lane to confirm what speed you should be doing.
• Controlled motorway: three regular lanes with a hard shoulder, but variable speed limits managed by overhead gantries.
• Dynamic Hard Shoulder: the hard shoulder opens as a running lane during congestion. A red X means it is closed and you must not drive in it.

A red X on a gantry is a legal instruction, not a suggestion. Driving under a red X is a £100 fine and three points minimum. If you see one, leave that lane. The other gantry signal that catches people out is the variable speed limit. If the gantry says 50, the limit is 50, and average speed cameras will be running.

#What are the UK motorway lane discipline and overtaking rules?

The single most common motorway mistake by full licence holders is sitting in lane two when lane one is clear. Lane two is for overtaking. Sitting in it for miles is technically careless driving, gets in the way of faster traffic, and is the source of most road rage incidents. After every overtake, return to lane one when it is safe to do so.

When you do overtake, plan it. Mirror, signal, mirror, manoeuvre, with a deliberate blind-spot check before you move. Pass the slower vehicle decisively, then check your left mirror and move back across when you can see the front of the vehicle you just passed in your interior mirror. Do not undertake. The exception is in queueing traffic, where lane-by-lane progress is allowed if your lane is moving faster than the one to your right.

#What should you do if you break down on a UK motorway?

On a traditional motorway with a hard shoulder, pull as far left as you can, get out via the passenger door, and stand behind the barrier. Call National Highways on 0800 028 1212 or use a roadside emergency phone (they connect directly). Do not stand near the car. On an All Lane Running motorway, the rules change. If you can reach an Emergency Refuge Area or motorway exit, do so. If not, switch on your hazards, leave the vehicle if it is safe, and get behind the barrier. National Highways will close your lane via the gantry within minutes.

For a deeper dive on weather and visibility, the fog and rain conditions guide covers what changes at speed. Once you have a few motorway hours behind you, the rest of the guides library is worth a browse.

#What are the most common UK motorway first-time mistakes?

• Joining too slowly: building to 50 mph on the slip road and trying to merge into 70 mph traffic
• Drifting: long stretches of straight road can lull new drivers into wandering across lane lines
• Tailgating in lane two: you cannot close a gap to push someone aside on a motorway
• Missing exits: trying to swerve across three lanes at the last moment is dangerous; if you miss it, take the next exit
• Tunnel vision: scanning only the car ahead, not the gantry, the mirrors, or two cars ahead
