A sleeper cab can create extra blind spots. Look out for vehicles just to the rear offside and nearside of your cab - they could soon become hidden in your blind spots.

Passing the moped and then turning into the junction could mean that you cut across in front of the rider. This might cause them to slow down, stop or even lose control.

Potholes and raised drain covers in the road can unsteady a motorcyclist. They may suddenly swerve to avoid these uneven surfaces. Watch out at places where the road is in poor condition and this is likely to occur.

With a front-tyre blow-out, you won't be able to steer properly. Keep a firm hold of the steering wheel and slow gradually to a stop. Don't brake hard or steer sharply.

If your vehicle is involved in a traffic incident, you must stop. Follow the guidance set out in The Highway Code if there's injury or damage to any other person, vehicle or property.

Poor planning leads to late braking and harsh acceleration. This causes higher fuel consumption and increased emissions, which is harmful to the environment.

You mustn't make a U-turn on roads where this sign is displayed.

When you need to drive close to the kerb, be aware of the dangers.

• Pedestrians may step off the kerb.
• The nearside mirror may be at a pedestrian's head height.
• Cyclists may be tempted to pass you on your left if you're driving slowly in congested conditions.

ISO (International Standards Organization) cargo containers should only be carried on lorries or trailers with the appropriate securing points. These are designed to lock into the container body.

Vehicles over the weight shown on the sign may not use the bridge ahead. You must know the weight of your vehicle, including any load. With this knowledge you should plan your route in advance, so that you don't come to a bridge you can't cross. That way, you'll avoid delays and save time and fuel.

Today, all water-cooled engines use a mixture of water and anti-freeze to make up the coolant. As well as helping to keep the engine at its correct operating temperature, the anti-freeze acts as a corrosion inhibitor to prolong the life of the cooling system.

The endurance brake (retarder) slows the vehicle without the use of the wheel-mounted brakes. However, care should be taken in slippery conditions, when the retarder's effect can be powerful enough to cause a skid.

When turning right onto a dual carriageway, don't stop in the gap in the central reservation unless your vehicle will fit in the gap without any overhang. When it's busy, consider turning left and using a roundabout further up the road so you don't have to cross the central reservation.

On multi-axled vehicles, the inside wheels on the rear twin-axle are the most difficult to check for punctures and damage. A deflated tyre will transfer the weight to the second tyre of the twin-axle pair. This will overload it and could cause it to burst.

Wind deflectors reduce a vehicle's wind resistance and so help reduce fuel consumption.

You should always plan your route. This will ensure you always drive on roads that are suitable for the size and weight of your vehicle. By planning to avoid peak travel times, you can also avoid congestion. This can save you fuel, as well as reducing your journey times.

If the trailer begins moving while you're working on it, you could put yourself and others in great danger. You must make sure that it's properly secured by the brake before you start work.

It's illegal to drive a vehicle that's emitting excessive exhaust smoke, so you should get the problem fixed as soon as you're aware of it. Excessive exhaust smoke increases pollution and creates a hazard for other road users.

You should be aware that motorcyclists are likely to be affected by side wind and can be blown into your path. Adjust your speed so that you can stop or take avoiding action safely if necessary.

Before driving into a tunnel, you should take off your sunglasses. If you don't, you'll find that your vision is restricted - even in a tunnel that appears to be well lit.

No motor vehicles are allowed past this sign. Although a motorcycle and car are shown, the restriction applies to all motor vehicles.

Red Routes operate in many busy cities and are designed to ensure the route has no obstructions to cause delays during peak periods. Road signs and red road markings identify roads where Red Route waiting and loading restrictions apply.

Research shows that approximately 40% of SRVIs involve commercial vehicles. The consequences are usually very serious because of the size of the vehicle and the fact that there is no braking before the impact.

Warning buzzers are linked to many systems on modern vehicles, including the air brakes. A warning light on the dashboard may help you identify the system that's caused the problem. Stop in a safe place until the fault has been identified and put right. Get professional help if necessary.

If there's any danger that the load you're lifting with a crane is too heavy for ropes or straps, or that sharp edges on the load may damage them, you should use chains with compatible tensioners.

In shopping areas, pedestrians frequently want to cross the road. They may be hidden by parked vehicles before stepping out into your path. Keep your speed down and be aware of the risk of pedestrians suddenly walking into the road.

At night, you can tell whether a vehicle is facing towards or away from you by the colour of its lights. Additionally, its brake lights or indicators can give you information about its direction and intentions. This information helps you to make safe driving decisions.

Some highly dangerous chemicals have to be transported at prescribed temperatures. Drivers must be fully trained in the use of these specially designed, temperature-controlled vehicles.

Look out for cyclists who don't have lights on. Also be aware that pedestrians - especially those in dark clothing - may be difficult to see.

Whenever possible, call the emergency services first. If you're able to give first aid, remember DR ABC. Check for Danger, then check the casualty for a Response. Check the Airway, and try to establish Breathing by gently lifting the chin up and forward. Give Compressions if necessary. Try to stop any severe bleeding. If you feel you aren't capable of carrying out first aid, consider taking some training. It could save a life.
