Drink driving questions make up a significant portion of the theory test. Clare’s 4,200 learner drivers need to know the blood alcohol limits (20mg for learners), penalties, and the myths around sobering up.
Clare’s road network ranges from the Shannon Airport approaches and Ennis bypass to the wild coastal roads of the Burren and Cliffs of Moher. Ennis’s medieval street pattern has narrow lanes and tight turns. The N18 motorway to Galway carries heavy traffic. Summer tourist traffic on the Wild Atlantic Way creates unusual congestion patterns on roads normally quiet. Fog rolling in from the Atlantic is a genuine and frequent hazard.
Drink driving questions require specific number knowledge — blood alcohol limits, penalty point values, and common myths about sobering up. They make up a significant portion of the theory test.
Key numbers: Legal BAC limit for learner/novice drivers: 20mg per 100ml of blood (lower than the 50mg limit for experienced drivers). Penalty: 3 penalty points and €200 fine for first offence (learners). Driving while impaired by drugs carries the same penalties. A learner with 7 penalty points loses their licence (vs 12 for full licence holders).
Study approach: Memorise the BAC limits for both learner and full licence holders. Learn that time is the only thing that reduces blood alcohol — coffee, fresh air, cold showers, and food do NOT speed up the process. The body processes roughly one standard drink per hour.
Common trap: Questions about “the morning after” — you can still be over the limit the morning after a night of drinking. Many people get these wrong because they assume sleep clears alcohol.
