Every year, many people are seriously injured by falling from vehicles. Using suitable steps will lessen the chance of falling. Be aware of the dangers when loading or unloading vehicles.

The formula used to calculate the payload of a vehicle is the maximum authorised mass (MAM) minus the tare weight. The tare weight is the total weight of the vehicle, including the crew and extra equipment.

You can help someone suffering from shock by talking to them and reassuring them confidently. Don't leave them alone or give them anything to eat or drink.

If you're waiting to emerge from a side road, remember to look for motorcycles. Their small size makes them easy to overlook. Be especially careful if parked vehicles are restricting your view. If you can't see, don't go.

Road-friendly suspension reduces the vibration caused by the impact of the wheels on the road surface.

Jack-knifing occurs when the tractor unit is pushed by the semi-trailer pivoting around the coupling (fifth wheel). This is more likely to occur with an unladen vehicle.

If your vehicle touches bells suspended over the road, they'll obviously ring. This will warn you that your vehicle exceeds the safe travelling height beneath electrified overhead cables ahead. You must stop immediately and either find another route or take advice.

At a pelican crossing, the green light means you may go, but you must give way to anyone still crossing. If someone hasn't finished crossing, be patient. People with mobility difficulties can struggle to cross in the time allowed by the lights.

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.

When starting an engine fitted with an engine management system, you don't need to press the accelerator, because the engine management system automatically regulates the fuel/air supply. Using the accelerator at start-up wastes fuel, causes increased engine noise and is harmful to the environment.

Just like your bus tyres, your trailer tyres must be in good condition. You might not tow a trailer on every journey you make, but when you do, check the trailer tyres while they're cold and make sure they're suitable for the load they'll carry.

You must take extra care when your vehicle is carrying a load. When cornering, weight will be transferred away from the direction in which you're turning. Also, when you're braking, weight can be transferred in several different directions.

Your vehicle will make more noise than a car, so you should try to avoid making unnecessary noise at any time of the day or night. This is especially important when you're in a residential area at a time when people are likely to be sleeping.

When carrying high-value goods, you can become a target for thieves. Avoid developing a set routine or pattern. Vary your routes whenever possible to make it difficult for thieves to predict when and where your cargo can be intercepted.

The priority when dealing with an unconscious person is to make sure they have a clear airway and can breathe. Stay with the casualty and make sure someone rings for an ambulance.

Don't rely on an audible warning device to claim right of way. It's your responsibility to be cautious and take all-round observation while you're reversing.

A motorcycle can be lost out of sight behind another vehicle. The use of the headlights helps to make the motorcycle more easily seen.

Whenever you uncouple a trailer, you must work through the uncoupling process methodically. Start by making sure that the brakes are applied on both the vehicle and the trailer.

It's important to stow away all your electrical cables and air lines safely to avoid causing injury to others. Connectors left lying around can be a trip hazard and can be damaged if they're run over by another vehicle.

Sitting in a high cab doesn't always give you all-round visibility. Other road users might assume that you can see them and position themselves out of sight close to your vehicle. Making good use of any extra mirrors can help prevent dangerous incidents, especially when parking.

To lift a load manually, your feet should be apart, with one leg slightly forward to help you keep your balance. Place one foot alongside the load if it's on the ground. Be prepared to move your feet to keep a stable position.

An unladen vehicle that also has high sides will be vulnerable to the effects of strong side wind. An evenly distributed load will help to keep the vehicle more stable, but the higher the vehicle is, the more it will be affected. Be aware that such a vehicle may become unstable or difficult to control in windy conditions.

Endurance brakes or 'retarders' help to control a vehicle's speed. They operate by applying resistance to slow the vehicle without using the wheel brakes, so avoiding brake fade. The methods used include: increased engine braking, exhaust braking and transmission-mounted devices.

The horn shouldn't be used between 11.30 pm and 7.00 am in a built-up area. The only exception is when another road user is unaware of you and poses a danger.

High vehicles are often directed to the centre of the road to go under an arched bridge. Check that your vehicle doesn't exceed the height restriction indicated. Plan your route in advance to avoid any bridges that your vehicle won't be able to clear.

If you see a contraflow sign, there'll also be markings on the road to indicate the bus lane. Don't use this lane for parking or overtaking.

Warn other traffic of the incident, without putting yourself or others at risk. Once the danger of further collisions is dealt with, call the emergency services. While you're waiting for them to arrive, keeping casualties or witnesses calm is important, but never offer a cigarette because of the risk of fire.

Wide loads are a hazard to other road users. In addition to having an attendant with you, you must notify the police if your load is wider than 3.5 metres [11 feet 5 inches]. Side markers must also be used to show other road users the limits of your vehicle.
