Question 1 of 10
What’s badly affected if the tyres are under-inflated?CorrectIncorrect
Your tyres are your only contact with the road. To prevent problems with braking and steering, keep your tyres free from defects; they must have sufficient tread depth and be correctly inflated. Correct tyre pressures help reduce the risk of skidding and provide a safer and more comfortable drive or ride.
Question 2 of 10
When mustn’t you sound your vehicle’s horn?CorrectIncorrect
Every effort must be made to prevent excessive noise, especially in built-up areas at night. Don’t rev your engine or sound the horn unnecessarily. It’s illegal to sound your horn in a built-up area between 11.30 pm and 7.00 am, except when another road user poses a danger.
Question 3 of 10
What makes the vehicle in the picture ‘environmentally friendly’?CorrectIncorrect
Trams are powered by electricity and therefore don’t emit exhaust fumes. They ease traffic congestion by offering drivers an alternative to using their car, particularly in busy cities and towns.
Question 4 of 10
Why have ‘red routes’ been introduced in major cities?CorrectIncorrect
Inconsiderate parking can obstruct the flow of traffic and so make traffic congestion worse. Red routes are designed to prevent this by enforcing strict parking restrictions. Driving slowly in traffic increases fuel consumption and causes a build-up of exhaust fumes.
Question 5 of 10
What’s the purpose of road humps, chicanes and narrowings?CorrectIncorrect
Traffic-calming measures help to 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 they are with a vehicle travelling at 40 mph.
Question 6 of 10
What’s the purpose of a catalytic converter?CorrectIncorrect
Catalytic converters reduce a large percentage of harmful exhaust emissions. They work more efficiently when the engine has reached its normal working temperature.
Question 7 of 10
It’s essential that tyre pressures are checked regularly. When should this be done?CorrectIncorrect
Check the tyre pressures when the tyres are cold. This will give you a more accurate reading. The heat generated on a long journey will raise the pressure inside the tyre.
Question 8 of 10
When will your vehicle use more fuel?CorrectIncorrect
Check your tyre pressures frequently – normally once a week. If they’re 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.
Question 9 of 10
How should you dispose of a used vehicle battery?CorrectIncorrect
Batteries contain acid, which is hazardous, and they must be disposed of safely. This means taking them to an appropriate disposal site.
Question 10 of 10
What’s most likely to cause high fuel consumption?CorrectIncorrect
Accelerating and braking gently and smoothly will help to save fuel and reduce wear on your vehicle. This makes it better for the environment too.
