Only overtake on the left if traffic is moving slowly in queues and the traffic on your right is moving more slowly than the traffic in your lane.

This plate is used with level crossing warning signs: advance warning of light signals at a level crossing with or without a gate or barrier.

It’s a good idea to plan an alternative route in case your original route is blocked for any reason. You’re less likely to feel worried and stressed if you’ve got an alternative in mind. This will enable you to concentrate fully on your driving or riding. Always carry a map that covers the area you will travel in.

You should give way to traffic already on the motorway. Where possible they may move over to let you in but don’t force your way into the traffic stream. The traffic may be travelling at high speed so you should match your speed to fit in.

Before emerging right onto a dual carriageway make sure that the central reserve is deep enough to protect your vehicle. If it’s not, you should treat it as one road and check that it’s clear in both directions before pulling out. Neglecting to do this could place part or all of your vehicle in the path of approaching traffic and cause a collision.

A mandatory speed limit sign above the hard shoulder shows that it can be used as a running lane between junctions. You must stay within the speed limit. Look out for vehicles that may have broken down and could be blocking the hard shoulder.

If you wish to turn right into a side road take up your position in good time. Move to the centre of the road when it’s safe to do so. This will allow vehicles to pass you on the left. Early planning will show other traffic what you intend to do.

Cyclists approaching a roundabout in the left-hand lane may be turning right but may not have been able to get into the correct lane due to the heavy traffic. They may also feel safer keeping to the left all the way round the roundabout. Be aware of them and give them plenty of room.

If you can’t get your vehicle onto the hard shoulder, use your hazard warning lights to warn others. Leave your vehicle only when you can safely get clear of the carriageway. Do not try to repair the vehicle or attempt to place any warning device on the carriageway.

Try not to react by applying the brakes harshly. This could lead to further loss of steering control. Indicate your intention to pull up at the side of the road and roll to a stop.

The colours of the reflective studs on the motorway and their locations are
• red – between the hard shoulder and the carriageway
• white – lane markings
• amber – between the edge of the carriageway and the central reservation
• green – along slip road exits and entrances
• bright green/yellow – roadworks and contraflow systems.

Other traffic will have to pull out to pass you. They may have to use the other side of the road, and if you park near the brow of a hill, they may not be able to see oncoming traffic. It's important not to park at or near a bus stop as this could inconvenience passengers, and may put them at risk as they get on or off the bus. Parking near a junction could restrict the view for emerging vehicles.

If it's possible, and you can do so without causing further danger, it may be safer to drive a vehicle which is on fire out of the tunnel. The greatest danger in a tunnel fire is smoke and suffocation.

As you approach the vehicle, assess the situation. Due to its slow progress you will need to judge whether it is safe to overtake.

A long vehicle may have to straddle lanes either on or approaching a roundabout so that the rear wheels don’t cut in over the kerb.
If you’re following a long vehicle, stay well back and give it plenty of room.

Stay in the left-hand lane long enough to get used to the higher speeds of motorway traffic.

At the scene of an incident, always be aware of danger from further collisions or fire. The first priority when dealing with an unconscious person is to ensure they're breathing normally. If they’re having difficulty breathing, follow the DR ABC code.

If your vehicle is fitted with drum brakes they can get hot and lose efficiency. This happens when they’re used continually, such as on a long, steep, downhill stretch of road. Using a lower gear will assist the braking and help prevent the vehicle gaining momentum.

You'll see this sign if there has been an incident ahead and the motorway is closed. You must obey the sign. Make sure that you prepare to leave in good time. Don't cause drivers to take avoiding action by cutting in at the last moment.

Always check the road signs. Triangular signs are warningsigns and they will keep you informed of hazards ahead to help you anticipate problems.

Windscreen pillars can obstruct your view, particularly at bends and junctions. Look out for other road users, particularly cyclists and pedestrians, as they can be hard to see.

It’s important to keep a safe distance from the vehicle in front at all times. This still applies in congested tunnels even if you are moving very slowly or have stopped. If the vehicle in front breaks down you may need room to manoeuvre past it.

You should consider drivers behind as brake lights can dazzle. However, if you are driving in fog it’s safer to keep your foot on the footbrake. In this case it will give the vehicle behind extra warning of your presence.

You should be constantly scanning the road for clues about what is going to happen next. Check your mirrors regularly, particularly as soon as you spot a hazard. What is happening behind may affect your response to hazards ahead.

If a young child has stopped breathing, first check that their airway is open and then begin CPR. With a young child, you may only need to use one hand and you shouldn’t press down as far as you would with an adult. Continue the procedure until the child is breathing again or until a medical professional takes over.

Take extra care as the pedestrian may not be aware of vehicles approaching.

White lights at the rear of a car show that it is about to reverse. Sound your horn to warn of your presence and reduce your speed as a precaution.
