Answer key
- 1. Parking restrictions apply during certain hours — check the signs — A single yellow line indicates time-based parking restrictions. You must check nearby signs to find out exactly when parking is prohibited.
- 2. Stop immediately and obey the Garda's signal — A Garda's signal overrides all other traffic controls including traffic lights. You must stop and comply with the Garda's directions.
- 3. To be aware of traffic and road users who may be affected by the manoeuvre — The correct sequence is Mirror–Signal–Manoeuvre. Checking mirrors first tells you who is close behind or alongside, so you can signal and manoeuvre safely without cutting across or startling other road users.
- 4. Check your blind spot by glancing over your shoulder — Mirrors do not cover blind spots. A shoulder check (glancing over your shoulder) before the manoeuvre confirms no motorcycle or cyclist is alongside in the space mirrors cannot show.
- 5. 1.5 metres — Where the speed limit exceeds 50 km/h, drivers must give at least 1.5 metres of clearance to cyclists. Higher speeds mean greater impact force if something goes wrong.
- 6. Slow down; there may be many children crossing or getting into cars — School opening and closing times bring large numbers of children on foot and on bicycles. Speed must be reduced and extra caution applied.
- 7. Only when visibility is seriously reduced (generally below 100 metres) — Fog lights should only be used when visibility is seriously reduced, generally below 100 metres. Using them in clear conditions dazzles other drivers and is illegal. You must switch them off when visibility improves.
- 8. Loss of steering and braking when tyres ride on a film of water at speed — Aquaplaning happens when water builds up in front of the tyres faster than it can be displaced, lifting them off the road. It is most likely at higher speeds during heavy rain.
- 9. Up to ten times — Ice dramatically reduces tyre friction. Braking distances can be up to ten times longer on ice than on a dry road, so a large speed reduction and large following gap are essential.
- 10. Slow down, look towards the left edge of the road, and stop if necessary — Flashing full beam in retaliation dazzles the oncoming driver and creates a serious risk of a head-on collision. Instead, slow down, look towards the left edge of the road, and stop if necessary.
- 11. Driver fatigue, worn tyres, and higher speed — Fatigue lengthens reaction time; worn tyres reduce braking grip; higher speed increases both reaction distance and braking distance. All three raise overall stopping distance.
- 12. It impairs reaction time in a way similar to alcohol — Severe sleep deprivation produces impairment comparable to alcohol intoxication. Reaction time, decision-making, and hazard perception all deteriorate significantly when a driver is tired.
- 13. Give way to any pedestrians still on the crossing, then proceed if clear — A flashing amber at a pelican crossing means give way to pedestrians already on the crossing. Once the crossing is clear, drivers may proceed.
- 14. Stay well back, wait for a safe, clear, straight stretch before overtaking — Agricultural machinery is wide and slow. Drivers must be patient, stay back to see the road ahead, and only overtake on a straight, clear section with no oncoming traffic.
- 15. Never drink any alcohol before driving — Even small amounts of alcohol impair judgement, reaction time and coordination. The safest approach is never to drink any alcohol before driving.
- 16. It impairs judgement, slows reaction time and reduces coordination — Alcohol impairs judgement, slows reactions and reduces coordination even at low levels, making driving dangerous.
- 17. Check with your doctor or pharmacist whether the medicine affects your ability to drive — Some prescription medicines can impair concentration, reaction time or vision. Always consult your doctor or pharmacist before driving while on medication.
- 18. No, it is illegal whenever you are in charge of the vehicle with the engine running — Using a hand-held phone while you are in charge of a vehicle with the engine running is illegal, even when stationary at traffic lights.
- 19. In all seats, both front and rear, where one is fitted — Irish law requires every occupant of a car to wear a seat belt where one is fitted, in both front and rear seats.
- 20. In the front passenger seat when the airbag is active — A rear-facing child seat must never be placed on a front passenger seat with an active airbag because the airbag could cause fatal injury to the child in a collision.
- 21. It impairs reaction time and judgement, similar to alcohol — Fatigue significantly impairs reaction time, concentration and decision-making to a level comparable to alcohol impairment, making it extremely dangerous.
- 22. Take regular rest breaks and avoid driving when you would normally be asleep — Regular rest breaks and avoiding driving during your natural sleep hours are the most effective measures against fatigue-related accidents.
- 23. On your driving licence record, accumulating over a three-year period — Penalty points are applied to and remain on your driving licence record, accumulating over a three-year period.
- 24. They are automatically disqualified from driving — Reaching 12 penalty points triggers automatic disqualification from driving. The driver must surrender their licence.
- 25. It is a criminal offence that may result in disqualification — Refusing to provide a breath, blood or urine sample when lawfully required is a criminal offence and may result in disqualification.
- 26. Cause increased tyre wear on the outer edges and reduce steering response — Under-inflation causes the tyre sidewalls to flex excessively, wearing the outer edges faster and generating heat that can lead to a blowout.
- 27. Excessive wear in the centre of the tread and a harsher ride — Over-inflation makes the centre of the tread bulge and carry most of the load, wearing it unevenly and reducing the tyre's ability to absorb road shocks.
- 28. It causes unpredictable handling, particularly when cornering — Radial and cross-ply tyres have different flex characteristics; mixing them creates uneven grip and handling that can cause the driver to lose control.
- 29. Only in fog or falling snow where visibility is seriously reduced — Front fog lights must only be used in fog or falling snow where visibility is seriously reduced. Using them in clear conditions can dazzle other road users.
- 30. To warn other drivers of a breakdown or obstruction ahead — Hazard lights are intended as a warning device for stationary breakdowns or to alert following traffic to a sudden hazard; they should not be used while driving normally.
- 31. Have the ABS system checked by a qualified technician as soon as possible — A permanently illuminated ABS light means the system has detected a fault and may not function correctly; the vehicle should be inspected promptly.
- 32. A possible fault such as air in the system or a fluid leak, which must be fixed — A spongy brake pedal usually indicates air in the hydraulic braking system or a fluid leak, both of which reduce braking effectiveness and must be fixed.
- 33. Worn shock absorbers — Shock absorbers dampen suspension movement. Worn shocks let the vehicle continue bouncing, reducing tyre contact with the road and compromising control.
- 34. Because operating wipers on a dry screen can damage both the blades and the windscreen — Running wipers on a dry screen causes smearing, possible scratching of the glass, and rapid deterioration of the rubber wiper blades, so the reservoir should be kept topped up.
- 35. A rich fuel mixture — too much fuel is being burned — Black smoke from a petrol engine usually means incomplete combustion due to an overly rich air-fuel mixture, often caused by a faulty sensor or injector.
- 36. National Car Test — The NCT (National Car Test) is Ireland's mandatory roadworthiness test for private cars, administered by NCTS on behalf of the RSA.
- 37. White circle with a red border — Regulatory signs in Ireland are circular with a white background and red border. They give legally binding instructions that drivers must obey.
- 38. Orange — Roadworks signs use an orange background to make them highly visible and to distinguish temporary hazard warnings from permanent road signs.
- 39. No entry — The no-entry sign — a white circle with a red border and a thick horizontal red bar — prohibits vehicles from entering a road in that direction.
- 40. School ahead — children may be crossing — A yellow diamond sign showing children running or a school-like symbol warns of a school ahead and the likelihood of children crossing the road.
