DTT Rules of the Road 3

Question 1

What does a flashing amber traffic light mean?

Accepted Answer

Proceed with caution — the signal is not fully operational

Answer

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?

Accepted Answer

Traffic on the continuing road (the top of the T)

Answer

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?

Accepted Answer

Yes — a Stop sign requires a complete stop regardless

Answer

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?

Accepted Answer

Only use hazard lights when stationary to warn others of a breakdown or emergency stop

Answer

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?

Accepted Answer

Read a number plate from 20 metres in good daylight

Answer

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.
