DTT Alcohol, Drugs, and Safe Driving 3

Question 1

What is the minimum disqualification period for a first drink-driving offence in Ireland?

Accepted Answer

3 years

Answer

A first drink-driving conviction in Ireland carries a mandatory minimum disqualification of 3 years, in addition to a fine and a possible criminal conviction.

Question 2

Can you be prosecuted for drink driving the morning after drinking heavily?

Accepted Answer

Yes — if your BAC is still above the legal limit the morning after

Answer

Alcohol takes time to leave the body — roughly 1 unit per hour. After heavy drinking, BAC may still exceed the legal limit the following morning. A prosecution is possible if you drive above the limit.

Question 3

What effect does cannabis use have on driving ability?

Accepted Answer

It impairs reaction time, judgement, and tracking ability — increasing crash risk

Answer

Cannabis impairs reaction time, tracking ability, and hazard perception. Research links cannabis use to significantly increased crash risk — it is illegal to drive while impaired by cannabis in Ireland.

Question 4

What is 'passive impairment' and can it lead to a positive drug test?

Accepted Answer

Exposure to second-hand drug smoke — this can cause a very low positive result but rarely to a prosecutable level

Answer

Passive inhalation of cannabis smoke can cause very low THC levels in saliva or blood, but typically not at levels sufficient for prosecution in Ireland. It is not a reliable defence.

Question 5

How does alcohol affect your risk perception while driving?

Accepted Answer

It causes overconfidence — drivers underestimate risks and feel more capable than they are

Answer

Alcohol causes overconfidence — impaired drivers often feel more skilled and less aware of danger than they actually are. This is one of the most dangerous effects of alcohol on driving.
