Ireland Driving Test 26
This is a timed quiz. You will be given 60 seconds per question. Are you ready?
What can be adversely affected by under-inflated tyres?
Explantion: Under-inflated tyres can increase the effort required to steer the vehicle. Always make sure the tyres are properly inflated by checking the tyre pressures regularly. Incorrect tyre pressure adversely affects many of a vehicle's systems, including brakes, suspension and fuel consumption. in particular, under-inflated tyres can affect the vehicle's steering.
When is the use of the horn prohibited?
Explantion: You are not allowed to use the horn in a built-up area between 11:30pm and 7:00am unless there is a traffic emergency. Only use a horn to warn other road users of oncoming danger or if you need to make them aware of your presence for safety reasons. Using the horn does not give you an automatic right of way. Never use the horn to provoke a reaction from or to rebuke another motorist.
What can a driver do to maximise fuel efficiency while driving?
Explantion: The more extra weight is in your vehicle. the more fuel you use. Using a roof rack or a roof box increases wind resistance and this also increases fuel consumption — by as much as 15%. Remove roof racks and roof boxes when not in use.
What alternatives can drivers take to help protect the environment?
Explantion: Using public transport helps to protect the environment. Buses. trams and trains are a more environmentally friendly way to move large numbers of people especially in urban areas. Consider using public transport where possible — not only is it more environmentally friendly, but it can also be more cost-effective when you take the cost of fuel and parking charges into account.
What effect does a worn exhaust have on a vehicle?
Explantion: A vehicle with a worn exhaust will probably be noisier and will produce more polluting emissions. There are strict regulations governing the noise and emission levels of vehicles, and these are rigorously checked during a vehicle's NCT.
What can be achieved by the driving style known as ‘Eco-Driving’?
Explantion: The advantages of 'eco-driving include improved road safety, improved fuel consumption and reduced emissions. The eco-conscious driver becomes a more efficient driver because they learn to read the road further ahead and display better anticipation skills. This reduces the need for harsh acceleration and braking which results in a more economical style of driving and a smoother drive.
Under what circumstances should a driver increase the air pressure in the tyres before undertaking a long journey?
Explantion: Check the air pressure before you start a long journey, and when you inflate the tyres, make sure that you follow the vehicle manufacturers recommended tyre pressure This is the pressure that gives the best performance in road holding, efficient braking and fuel consumption.
How can fuel efficiency be improved?
Explantion: The way you drive can contribute to your vehicle's fuel efficiency: 1. Accelerate gently; 2. Use the highest available gear (without causing the engine to struggle): and 3. Drive smoothly—this also reduces wear and tear on a vehicle.
What should a driver do to minimise fuel consumption in their vehicle?
Explantion: Driving smoothly will help reduce your fuel consumption. Read the road ahead and adjust your speed in good time, and avoid harsh acceleration and late braking.
What is the effect of under-inflated tyres on a vehicle?
Explantion: Check the tyre pressure once a week. Incorrect tyre pressure adversely affects many of a vehicle's systems, including braking ability, suspension, steering and fuel consumption.
How does harsh acceleration affect fuel consumption?
Explantion: Harsh acceleration increases fuel consumption, and driving smoothly helps to reduce your fuel consumption and the emissions from your vehicle. Try not to over-rev the engine and use the appropriate gear for the speed of the vehicle. When slowing down, take your foot off the accelerator and allow the vehicle to slowly progressively before you brake.

This reduces the need for harsh acceleration and braking which results in a more economical style of driving and a smoother drive.
What can cause heavy steering?
Explantion: Heavy steering is when you need to use more effort than usual to turn the steering wheel. You might experience this if the power-assisted steering system is not working properly, or more commonly, if the front tyres are under-inflated.
Which action is likely to cause an increase in fuel consumption?
Explantion: Harsh acceleration increases fuel consumption. Driving smoothly reduces wear and tear and also improves fuel consumption. Use the highest gear possible without causing the engine to labour.
How does continuous high-speed driving affect fuel consumption?
Explantion: Driving at high speeds increases your fuel consumption. A vehicle travelling at 112km/h uses approximately 30% more fuel than one travelling at 80km/h.
Is a driver allowed to sound the horn while driving in a built-up area at night?
Explantion: You are not allowed to use the horn in a built-up area between 11:30pm and 7:00am unless there is a traffic emergency. Only use a horn to warn other road users of oncoming danger or if you need to make them aware of your presence for safety reasons. Using a horn does not give you an automatic right of way. Never use the horn to provoke a reaction from or to rebuke another motorist.
What effect would coasting have on a vehicle’s tyres?
Explantion: Coasting is a bad practice that happens when a driver allows a vehicle to move by its own momentum (or by gravity — for example, down a hill) with the engine disengaged. This can be done in two ways: 1. By putting the car into neutral gear while moving; or 2. By keeping the clutch pedal pressed down to disengage the selected gear. If a vehicle is coasting, the driver has much less control, so you should never coast. However, it has no effect on tyres.
What should a driver do to ensure better fuel efficiency from their vehicle?
Explantion: One of the keys to good fuel efficiency is making sure that your vehicle is well maintained. Servicing should be carried out as recommended by the manufacturer. Checking the tyre pressure regularly can also help ensure good fuel efficiency.
What should the driver do to secure the vehicle when changing a wheel?
Explantion: If you have to change a wheel, make sure you do it in a safe place on level ground. Also, apply the handbrake and engage a low gear to secure the vehicle before you jack it up.
While driving, what does a continuous vibration in the steering indicate?
Explantion: If you feel a continuous vibration in the steering, particularly at higher speeds, this could indicate that the balance of the vehicle wheels is uneven. If this is the case, you should have it investigated by a mechanic.
Under what circumstances is it permitted to replace the standard horn on a vehicle with a musical horn?
Explantion: A horn is designed to be an audible warning device. You should not make any technical modifications to the horn without professional advice as these may have legal and safety implications.
In what way do motor vehicles harm the environment?
Explantion: Carbon monoxide is a poisonous gas emitted by vehicle exhausts into the atmosphere. Driving economically and keeping a vehicle well maintained can reduce the level of carbon monoxide emissions.
What can a driver do to help the environment?
Explantion: Drivers should plan well ahead and avoid harsh acceleration and braking, both of which can waste fuel and increase pollution.
When driving, where should a driver rest their left foot?
Explantion: The clutch is the connection between the engine and the gearbox. It enables the vehicle to move when a gear is engaged. You should not rest your foot on the clutch pedal because it may disengage the selected gear or damage the clutch mechanism.
What can drivers do to help protect the environment?
Explantion: Car sharing helps the environment. Drivers should consider car sharing for routine journeys to work or for the school run. This will reduce pollution and reduce traffic congestion at peak times.
