DTT Rules of the Road 3 — Questions and Answers
Question 1: What does a flashing amber traffic light mean?
- Proceed with caution — the signal is not fully operational (Correct answer)
- Stop — treat as a red light
- Accelerate to clear the junction quickly
- Pedestrians have priority
Correct answer: Proceed with caution — the signal is not fully operational
A flashing amber light means the signals are not fully operational. Treat the junction with caution, give way as necessary, and proceed only when safe.
Question 2: Who has priority at an uncontrolled T-junction in Ireland?
- Traffic on the continuing road (the top of the T) (Correct answer)
- Traffic approaching from the right
- Traffic on the minor road must always yield
- Whoever arrives at the junction first
Correct answer: Traffic on the continuing road (the top of the T)
At an uncontrolled T-junction, traffic on the major continuing road (the 'top' of the T) has priority. The driver entering from the minor road (the 'stem') must give way.
Question 3: When approaching a STOP line at a junction with good visibility and no traffic, must you still stop?
- Yes — a Stop sign requires a complete stop regardless (Correct answer)
- No — if it is clearly safe, you may proceed slowly
- Only if another vehicle is approaching
- Stop signs are advisory at minor junctions
Correct answer: Yes — a Stop sign requires a complete stop regardless
A Stop sign always requires a complete halt before the stop line, regardless of visibility. This is a legal requirement, not merely an advisory guidance.
Question 4: What is the Irish rule on using hazard lights while driving?
- Only use hazard lights when stationary to warn others of a breakdown or emergency stop (Correct answer)
- Use hazard lights to thank other drivers
- Use hazard lights when driving slowly in heavy rain
- Hazard lights are permitted while driving at any time
Correct answer: Only use hazard lights when stationary to warn others of a breakdown or emergency stop
Hazard lights should only be used when stationary to warn others of a breakdown or hazard. Using them while moving (except briefly on a motorway to warn of a queue) is discouraged and can be dangerous.
Question 5: What is the minimum eyesight requirement for driving in Ireland?
- Read a number plate from 20 metres in good daylight (Correct answer)
- Read a number plate from 15 metres
- Pass a Snellen chart test at a doctor
- Have at least 6/12 vision in both eyes
Correct answer: Read a number plate from 20 metres in good daylight
Drivers in Ireland must be able to read a vehicle number plate from 20 metres in good daylight. This is a basic practical test of adequate visual acuity for safe driving.
Question 6: When must you stop for a school warden (lollipop person) in Ireland?
- Whenever they step into the road and display their sign (Correct answer)
- Only at designated school zones
- When children are actually crossing
- When the warden signals with a whistle
Correct answer: Whenever they step into the road and display their sign
You must stop as soon as a school warden steps into the road and raises their sign. It is an offence to fail to stop. You may not proceed until the warden has returned to the footpath.
