A To help protect the environment against pollution

explanation

Emission tests are carried out to ensure your vehicle's engine is operating efficiently. This ensures the pollution produced by the engine is kept to a minimum. If your vehicle is not serviced regularly, it may fail the annual MOT test.

You must NOT sound your horn

between 11.30 pm and 7 am in a built- up area

Vehicles can be noisy. Every effort must be made to prevent excessive noise, especially in built-up areas at night. Don’t rev the engine or sound the horn unnecessarily. It is illegal to sound your horn in a built-up area between 11.30 pm and 7 am, except when another vehicle poses a danger.

New petrol-engined cars must be fitted with catalytic converters. The reason for this is to

reduce harmful exhaust emissions

We should all be concerned about the effect traffic has on our environment. Fumes from vehicles are polluting the air around us. Catalytic converters act like a filter, removing some of the toxic waste from exhaust gases.

Your anti-lock brakes warning light stays on. You should

have the brakes checked immediately

Consult the vehicle handbook or garage before driving the vehicle. Only drive to a garage if it is safe to do so. If you’re not sure get expert help.

You will use more fuel if your tyres are

under-inflated

Check your tyre pressures frequently – normally once a week. If pressures are lower than those recommended by the manufacturer, there will be more ‘rolling resistance’. The engine will have to work harder to overcome this, leading to increased fuel consumption.

Road humps, chicanes, and narrowings are

traffic calming measures

Traffic calming measures help keep vehicle speeds low in congested areas where there are pedestrians and children. A pedestrian is much more likely to survive a collision with a vehicle travelling at 20 mph than at 40 mph.

It can help to plan your route before starting a journey. You can do this by contacting

a motoring organisation

Most motoring organisations will give you a detailed plan of your trip showing directions and distance. Some will also include advice on rest and fuel stops. The Highways Agency website will also give you information on roadworks and incidents and gives expected delay times.

To reduce the damage your vehicle causes to the environment you should

anticipate well ahead

By looking well ahead and recognising hazards in good time, you can avoid last-minute harsh braking. Watch the traffic flow and look well ahead for potential hazards so you can control your speed accordingly. Avoid over-revving the engine and accelerating harshly as this increases wear to the engine and uses more fuel.

You will find that driving smoothly can

reduce fuel consumption by about 15%

Not only will you save about 15% of your fuel by driving smoothly, but you will also reduce the amount of wear and tear on your vehicle as well as reducing pollution. You will also feel more relaxed and have a more pleasant journey.

How can missing out some gear changes save fuel?

By reducing the amount of time you are accelerating

Missing out some gears helps to reduce the amount of time you are accelerating and this saves fuel. You don’t always need to change up or down through each gear. As you accelerate between each gear more fuel is injected into the engine than if you had maintained constant acceleration. Fewer gear changes means less fuel used.

How should you dispose of a used car battery?

Take it to a local authority site

Batteries contain acid, which is hazardous, and they must be disposed of safely. This means taking them to an appropriate disposal site.

You are carrying a 5 year-old child in the back seat of your car. They are under 1.35 metres (4 feet 5 inches). A correct child restraint is NOT available. They MUST

use an adult seat belt

Usually a correct child restraint MUST be used. In a few exceptional cases if one is not available an adult seat belt MUST be used. In a collision unrestrained objects and people can cause serious injury or even death.

Where would parking cause an obstruction to others?

Near the brow of a hill

Think about the effect your parking will have on other road users. Don’t forget that not all vehicles are the size of a car. Large vehicles will need more room to pass and might need more time too. Parking out of the view of traffic, such as before the brow of a hill, causes unnecessary risks. Think before you park.

It is essential that tyre pressures are checked regularly. When should this be done?

When tyres are cold

When you check the tyre pressures do so when the tyres are cold. This will give you a more accurate reading. The heat generated from a long journey will raise the pressure inside the tyre.

Planning your route before setting out can be helpful. How can you do this?

Print or write down the route

Print or write down your route before setting out. Some places are not well signed so using place names and road numbers may help you avoid problems en route. Try to get an idea of how far you’re going before you leave. You can also use it to re-check the next stage at each rest stop.
