Ireland Driving Test 30
This is a timed quiz. You will be given 60 seconds per question. Are you ready?
What is jack-knifing?
Explantion: Towing a trailer or caravan dramatically reduces the stability of the towing vehicle. If a driver brakes sharply or slows down quickly, the trailer may pivot around the tow hitch coupling, causing both vehicles to go off course, and possibly overturn.
What is the purpose of a catalytic converter?
Explantion: Catalytic converters are part of most vehicles' exhaust system. They remove up to 75% of the carbon monoxide, nitrogen oxide and hydrocarbons from the vehicles' exhaust.
At what point is a vehicle load more likely to shift?
Explantion: It is the drivers responsibility to ensure that the load is properly secured and evenly distributed. so that the vehicle can be properly controlled when changing direction and when braking.
How should a driver secure their vehicle before getting out of it?
Explantion: Before leaving your vehicle, apply the handbrake, switch off the engine and engage low engage a low gear. If the vehicles if fitted with automatic transmission, select 'P' (park).
How regularly should a vehicle be serviced?
Explantion: You should have your vehicle serviced regularly in accordance with the manufacturer's guidelines. This helps the vehicle to perform properly, thus saving fuel and reducing emissions. You should also carry out your own daily and weekly checks on fluid levels and tyres.
When is a tractor most likely to overturn?
Explantion: Tractors are less stable than other vehicles as they have no suspension and the extra height and uneven positioning of the wheel adds to the instability. When you are driving a tractor, you should take these factors into account and take extra care when maneuvering.
When is it permissible for a driver to carry a passenger on a trailer drawbar?
Explantion: You must never carry a passenger on a trailer drawbar because of the danger of the passenger falling between the vehicle and the trailer and being seriously injured or killed.
What should a driver do if a tyre bursts on the vehicle they are driving?
Explantion: If a tyre bursts on your vehicle, keep a firm hold of the steering, slow down gradually and stop where it is safe to do so. Switch on the hazard warning lights.
What should a driver do in order to avoid excessive exhaust pollution from their vehicle?
Explantion: You should have your vehicle serviced regularly in accordance with the manufacturers guidelines. A vehicle that is poorly tuned uses more fuel and creates more exhaust pollution. Air filters should be changed as part of normal servicing. If a vehicle is used in dusty conditions, the air filter may need to be changed more often. More information is available in the vehicle's handbook.
How should a driver use the brakes if the vehicle is fitted with anti-lock brakes (ABS)?
Explantion: If your vehicle is fitted with ABS. brake firmly. ABS will not stop the vehicle more quickly, it will only prevent the wheels from locking. This helps you to maintain control of the vehicle.
What effect could a front-tyre blow-out have on a vehicle?
Explantion: If a front tyre on the vehicle you are driving blows out, you will feel the effect of it through the steering wheel. The wheel will generally pull to the side of the blown-out tyre.
On a busy road, how should a driver allow passengers out of a vehicle?
Explantion: Before allowing any door to be opened, check for other road users passing, and in particular look out for pedestrians, cyclists and motorcyclists. Passengers should exit on the side nearest the kerb, without getting in the way of pedestrians.
When attaching a trailer to their vehicle, what should a driver check?
Explantion: Proper weight distribution helps to ensure the stability of both the towing vehicle and the trailer. In the trailer, the bulk of the load should be over the axles. If a heavy load is positioned at the front of the trailer, this will result in too much 'nose weight' on the hitch of the towing vehicle and make it difficult to steer. If a heavy load is positioned at the rear of the trailer, this will result in reduced weight on the rear axle of the towing vehicle, which will make it more unstable.
What precaution should a driver take when getting out of their vehicle?
Explantion: Before opening any door, check for other road users passing, and in particular look out for pedestrians, cyclists and motorcyclists. Exit the vehicle only when it is safe to do so, and close the door as soon as possible. Passengers should exit on the side nearest the kerb wherever possible.
What should a driver do to secure the towing vehicle before unhitching a trailer?
Explantion: Before unhitching a trailer, apply the handbrake, switch off the ignition and engage a lower gear, so that the towing vehicle does not move while you are unhitching the trailer.
What should a driver do if their vehicle gets into a front-wheel sideways skid?
Explantion: If your vehicle goes into a front-wheel sideways skid, release the accelerator and do not try to steer until the tyres regain some grip on the road.
What type of noise might fast cornering create?
Explantion: If you drive around a corner too fast, the tyres begin to lose contact with the surface of the road, and this causes a squealing sound. If you continue driving in this way, you can lose control of the vehicle.
What should a driver do when requested to drive a vehicle that they feel is overloaded?
Explantion: You should not take a vehicle that you believe to be overloaded onto a public road. Overloading is dangerous, as it affects the stability and braking capabilities of the vehicle.
When attaching a trailer to their vehicle, what should a driver check?
Explantion: Before towing a trailer or a caravan, check that the towbar is securely attached to the towing vehicle, that the trailer coupling is properly attached to the towbar and locked in place, and that the breakaway cable is properly connected.
What should a driver do if their vehicle gets into a rear-wheel sideways skid?
Explantion: If your vehicle goes into a rear-wheel sideways skid, turn the steering in the direction the rear wheels are heading. This should be done very gradually, as too much steering could cause the vehicle to skid in the opposite direction.
The driver of a tractor pulling a wide load that blocks their view to the rear wishes to turn right. What should they do?
Explantion: If you are driving a vehicle with a wide load that blocks your view of the road to the rear, and you need to turn right, you should get someone else to look out to the rear and advise you when it is safe to make the turn.
When is jack-knifing most likely to occur?
Explantion: Towing a trailer or caravan dramatically reduces the stability of the towing vehicle If a driver brakes sharply or slows down quickly, the trailer may pivot around the tow hitch coupling, causing both vehicles to go off course, and possibly overturn.
When driving a tractor and trailer, what should the driver do on entering a roundabout to avoid possible roll-over?
Explantion: When you are driving a tractor with a trailer, you need to take extra care because of the vehicle's instability. Always drive at a safe speed, in particular when changing direction, such as on a roundabout.
What should a driver do before getting out of the vehicle?
Explantion: Before opening any door, check for other road users passing, and in particular look out for pedestrians, cyclists and motorcyclists. Exit the vehicle only when it is safe to do so, and close the door as soon as possible. Passengers should exit on the side nearest the kerb wherever possible.
What should a driver do if their vehicle gets into a four-wheel sideways skid?
Explantion: If your vehicle goes into a four-wheel skid, turn the steering wheel in the same direction as the skid and ease off the accelerator. This should help to bring the wheels back into line and allow you to regain control.
How should a driver in a vehicle without anti-lock brakes (ABS) deal with a front-wheel straight-line skid?
Explantion: If your vehicle does not have ABS and it goes into a straight-line front-wheel skid due to braking. press and release the brake pedal repeatedly and rapidly. This will help to restore tyre grip and enable you to regain control.
How could towing an overloaded trailer affect a vehicle?
Explantion: You should not take an overloaded trailer onto a public road. An overloaded trailer impairs the stability, steering and braking of the towing vehicle.
