Faulty power steering will make your steering wheel very difficult or almost impossible to turn. Continuing to drive could cause danger to you and other road users. You should park safely and get help.

The risk of fire will be reduced if all fuel supplies are switched off. However, don't put yourself or your passengers at any risk. If there's a fire, call the fire service.

A long lorry with a heavy load will need more time to pass you than a car. It won't be able to accelerate enough to pass you quickly, especially on an uphill stretch of road. Be considerate to the lorry driver - ease off the accelerator and allow the lorry to pass.

By planning your journey to avoid busy times, you'll avoid the build-up of traffic that often occurs.

In windy weather, try to avoid routes where you would have to drive across suspension bridges and other exposed stretches of road. Plan a route that takes you across lower ground and where you'll be less exposed.

Approaching a junction at the correct speed will allow you enough time to observe and react. Pedestrians crossing here have priority and you must give way to them.

Always maintain a safe following distance from the vehicle in front. If another vehicle pulls into the gap, slow down to re-establish a safe following distance. Following too close is dangerous and places you and other road users in unnecessary danger; your view of the road ahead will be seriously reduced, and you won't be able to see or plan effectively.

Fluids carried in tankers can move in waves as the vehicle's speed or direction changes. This happens particularly when you brake and then ease off the pedal; the moving wave of liquid causes the vehicle to surge forward. Baffle plates are designed to reduce this surging effect.

If you're travelling on a long journey, plan your route before you leave. This will help you to

• be decisive at intersections and junctions
• plan your rest stops
• know approximately how long the journey will take.

Make sure that the vehicle you're travelling in is well ventilated. A warm, stuffy atmosphere can make you drowsy, which will impair your judgement and perception.

Keeping your vehicle's tyres in good condition will give them a good grip on the road and will improve the vehicle's overall stability. Each tyre must have at least the minimum legal depth of tread across three-quarters of its width. Renew tyres well before they wear to less than that.

Don't remove anything sticking to a burn. You may cause further damage and introduce infection into the wound. If you can, douse the burn with clean cold water or other non-toxic liquid for at least 10 minutes.

Elderly pedestrians may have impaired judgement, hearing and/or vision. Be aware that, if they do start to cross, they could take more time to do so.

Fuel spilled on the road is a serious danger to other road users, especially motorcyclists. To prevent this from happening, make sure the filler cap is secure after refuelling.

Always check carefully for cyclists when emerging from a junction. Bicycles, being much narrower than any other vehicle, can be quite difficult to see.

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.

Spray-suppression equipment reduces the amount of spray thrown up to other road users. Check the equipment regularly to make sure it's secure and undamaged.

Driving in a fuel-efficient manner means that you plan well ahead for hazards and react in good time. This can save fuel and is therefore good for the environment.

Don't move a casualty who's in a safe place, as this could worsen any injury they may have. Only move a casualty if they're in danger - for example, from passing traffic. You may also need to move them if you need to give lifesaving first aid, such as clearing their airway.

Unless the curtains are specifically designed, they must not be used to restrain the load. They should be used to protect it from the weather and provide a level of security. Most companies also use them as a mobile advertisement.

The endurance brake (retarder) usually operates by applying resistance, via the transmission, to the vehicle's driven wheels. If the road is slippery, the tyres may lose grip and the wheels will lock.

Most incidents happen as a result of a lapse in concentration. Don't let this happen to you. If you start to feel tired, you won't perform as well as you should. Your reactions will slow down, and your anticipation and judgement of hazards will become flawed. If you feel tired, stop and rest as soon as it's safe to do so.

You must take 35 hours of training every five years to maintain your Driver CPC. This can be done at any time during the five years: all at once or split into sessions of at least seven hours each. The penalties for non-compliance are the same as those for driving without a licence.

The speed limit for lorries is lower in Scotland than it is in England and Wales, so be aware - especially if you drive in the border areas.

The pump creates a vacuum in the servo unit. This reduces the amount of pressure you need to apply to the brake pedal. Without this vacuum, it's extremely difficult to press the brake pedal down.

If you notice any missing wheel nuts, park and phone for assistance. It's essential that all wheel fixings are in place and tightened to the torque specified by the manufacturer. Checks should be made before you start any journey, but make a visual check every time you start up again after a rest stop.

In icy or snowy weather, your stopping distance can increase by up to ten times. Because snowy weather increases the distance needed to stop, you must look further ahead and leave an increased safety margin.

Before using the crane, it's vital to make sure the vehicle is parked on level ground and the stabilising legs are lowered. This will reduce the risk of the load becoming unstable during lifting. Also check for any overhead cables that may obstruct the crane.

Only overtake when it's safe to do so, and don't use the size of your vehicle to intimidate approaching traffic. When overtaking a cyclist, leave plenty of room and, before returning to the left, check in your nearside mirror to make sure you've passed them safely.

If your vehicle is too long to fit into a passing place, you may need to wait opposite one. This will allow a following or approaching driver to pass. When you use this type of road, you need to plan and look well ahead to avoid meeting another road user at an inappropriate place.
