K53 Learners Alcohol, Drugs and Fatigue 3

Question 1

Which of the following methods will effectively and quickly sober up a person who has been drinking?

Accepted Answer

None of the above — only time reduces blood alcohol

Coffee, food, exercise and cold showers do not speed up the elimination of alcohol; only time and the liver's natural metabolism reduce BAC.

Question 2

The use of cannabis (dagga/marijuana) and driving in South Africa is:

Accepted Answer

Illegal and an offence under the National Road Traffic Act

Driving under the influence of any illegal drug, including cannabis, is an offence under the National Road Traffic Act regardless of medical status.

Question 3

How does fatigue affect a driver's reaction time?

Accepted Answer

It significantly slows reaction time, similar to alcohol impairment

Research shows that driving after 17–18 hours without sleep produces impairment similar to a BAC of 0.05g/100ml.

Question 4

A passenger in your vehicle notices you are showing signs of fatigue. What is the most appropriate action?

Accepted Answer

Stop, rest, then allow the passenger to drive if licensed

Answer

The safest course is to stop at a safe location first, rest briefly, and then allow a licensed and alert passenger to drive.

Question 5

Which of the following statements about the legal blood alcohol limit is CORRECT?

Accepted Answer

Any amount of alcohol can impair driving ability, even below the legal limit

Even small amounts of alcohol below the legal limit can impair judgement and reaction time; the legal limit is a legal threshold, not a safety guarantee.
