At roadworks, and especially where a contraflow system is operating, a speed restriction is likely to be in place. Keep to the lower speed limit and don't

• switch lanes
• get too close to the vehicle in front of you.

Be aware that there will be no permanent barrier between you and the oncoming traffic.

The flashing amber light allows pedestrians already on the crossing to get to the other side before a green light shows to the traffic. Be aware that some pedestrians, such as elderly people and young children, need longer to cross. Let them do this at their own pace.

A red cross above the hard shoulder shows that it's closed as a running lane and should only be used for emergencies or breakdowns. On a smart motorway, the hard shoulder may be used as a running lane at busy times.

Have your eyesight tested before you start your practical training. Then, throughout your driving life, have checks periodically to ensure that your eyes haven’t deteriorated.

A tyre bursting can lead to a loss of control, especially if you’re travelling at high speed. Using the correct procedure should help you to stop the vehicle safely.

Talk to the casualty and keep them calm. Do not attempt to move them as this could cause further injury. Call an ambulance at the first opportunity.

A heavy load on your roof rack will reduce the stability of the vehicle because it moves the centre of gravity away from that designed by the manufacturer. Be aware of this when you negotiate bends and corners. If you change direction at speed, your vehicle and/or load could become unstable and you could lose control.

Be responsible and only drive if you are fit to do so. Some medication can affect your concentration and judgement when dealing with hazards. It may also cause you to become drowsy or even fall asleep. Driving while taking such medication is highly dangerous.

Police officers may need to direct traffic, for example, at a junction where the traffic lights have broken down. Check your copy of The Highway Code for the signals that they use.

Do not move a casualty unless therev is further danger, for example, from other traffic or fire. They may unseen or internal injuries. Moving them unnecessarily could cause further injury. Do NOT remove a motorcyclist's helmet unless it is essential.

Poor contact with the road surface could cause one or more of the tyres to lose grip on the road. This is more likely to happen when braking in poor weather conditions and when the road has a loose or uneven surface.

You should carry out frequent checks on all fluid levels but particularly brake fluid. As the brake pads or shoes wear down the brake fluid level will drop. If it drops below the minimum mark on the fluid reservoir, air could enter the hydraulic system and lead to a loss of braking efficiency or complete brake failure.

The continuous white line shows the edge of the carriageway. It can be especially useful when visibility is restricted, for example at night or in bad weather. It is discontinued where it crosses junctions, lay-bys etc.

On the approach to tunnels a sign will usually show a local radio channel. It should give a warning of any incidents or congestion in the tunnel ahead. Many radios can be set to automatically pick up traffic announcements and local frequencies. If you have to tune the radio manually don’t be distracted while doing so. Incidents in tunnels can lead to serious casualties. The greatest hazard is fire. Getting an advance warning of problems could save your life and others.

Hold back and allow the cyclist to move off. In some towns, junctions have special areas marked across the front of the traffic lane. These allow cyclists to wait for the lights to change and move off ahead of other traffic.

If you see a triangular sign with a row of cars on it, it's warning you that you're approaching a congested area, so be prepared to stop. The queues ahead might be hidden, so make sure you're aware of vehicles behind you that could be following too closely.

As the registered keeper of a vehicle it is up to you to inform DVLA (DVA in Northern Ireland) of any changes in your vehicle or personal details, for example, change of name or address. You do this by completing the relevant section of the Registration Certificate and sending it to them.

DO NOT remove a motorcyclist’s helmet unless it is essential. Remember they may be suffering from shock. Don’t give them anything to eat or drink but do reassure them confidently.

Learners might not have confidence when they first start to drive. Allow them plenty of room and don’t react adversely to their hesitation. We all learn from experience, but new drivers will have had less practice in dealing with all the situations that might occur.

If you’re involved in a collision, head restraints will reduce the risk of neck injury. They must be properly adjusted. Make sure they aren’t positioned too low, in a crash this could cause damage to the neck.

Fitting a stabiliser to your tow bar will help to reduce snaking by the caravan especially where there are crosswinds. However, this does not take away your responsibility to ensure that your vehicle/caravan combination is loaded correctly.

Except in a genuine emergency you MUST NOT use your mobile phone when driving. If you need to use it leave the motorway and find a safe place to stop. Even a hands-free phone can distract your attention. Use your voicemail to receive calls. Driving requires all of your attention, all of the time.

Deep water can affect your brakes, so you should check that they’re working properly before you build up speed again. Before you do this, remember to check your mirrors and consider what’s behind you.

This sign tells you that you are not permitted to make a U-turn. It is commonly displayed on approach to junctions on dual carriageways.

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.

At a pelican crossing the green light means you may proceed as long as the crossing is clear. If someone hasn’t finished crossing, be patient and wait for them.
