Alcohol, Drugs, and Safe Driving Flashcards

What is the impact of alcohol on a driver's ability to judge speed and distance?

Answer: Alcohol impairs depth perception and makes it harder to judge speed and distance accurately

Alcohol impairs depth perception and spatial awareness, making it difficult to accurately judge the speed of approaching vehicles or the distance to objects. This is critical when overtaking or merging.

If you are involved in a collision and you had consumed alcohol but were under the legal limit, can you be prosecuted?

Answer: Yes — if evidence shows alcohol contributed to dangerous or careless driving

Being under the legal BAC limit does not automatically mean you cannot be prosecuted. If alcohol contributed to dangerous or careless driving, a prosecution can still follow on those grounds.

What effect do tranquillisers (sedatives) have on driving?

Answer: They cause drowsiness and slowed reactions — driving is dangerous while taking them

Tranquillisers and sedatives cause drowsiness, slowed reflexes, and impaired concentration. These effects make driving dangerous and the driver may be prosecuted for impaired driving.

What warning must appear on medication packaging that may impair driving?

Answer: A warning label advising not to drive or operate machinery

Medications that may impair driving must carry a warning on the packaging, such as 'May cause drowsiness — do not drive or operate machinery.' This is a European regulatory requirement.

What is the 'Dutch courage' effect of alcohol in terms of driving risk?

Answer: Alcohol causes false confidence — drivers take greater risks while being less capable of managing them

The 'Dutch courage' effect describes alcohol increasing risk-taking behaviour while simultaneously reducing the physical and cognitive ability to handle those risks — a deadly combination in driving.

What is the best source of information about whether your medication affects driving?

Answer: Your doctor, pharmacist, or the medication's patient information leaflet

Your doctor and pharmacist are the most reliable sources of advice about whether a specific medication impairs driving. The patient information leaflet also contains specific driving warnings.
