What is the legal blood alcohol limit for a professional driver (e.g. taxi or bus driver) in South Africa?

Answer: 0.02 grams per 100 millilitres

Professional drivers face a stricter limit of 0.02g per 100ml blood because they carry passengers and bear greater responsibility.

Driving under the influence of alcohol in South Africa is classified as:

Answer: A criminal offence

Driving under the influence (DUI) is a criminal offence under the National Road Traffic Act and can result in criminal prosecution.

What is the general speed limit on a freeway in South Africa unless otherwise posted?

Answer: 120 km/h

The general maximum speed on a freeway is 120 km/h unless road signs indicate a lower limit.

A painted island or chevron area marked with diagonal lines on the road should be treated how?

Answer: As an area you should not drive over or stop in

Chevron/painted island areas separate traffic streams. You should not drive over or stop in them; keep to the proper lane.

How does fatigue affect a driver's reaction time?

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.

What does the handbrake (parking brake) do?

Answer: Holds the vehicle stationary when parked or stopped on a hill

The handbrake holds the vehicle still when parked and helps prevent rolling, especially when stopped or pulling away on an incline.

A green rectangular sign with white text and arrows on a freeway is what type of sign?

Answer: A freeway direction/guidance sign

Green signs with white lettering give direction and destination information on freeways. They guide you to towns, exits and routes.

In South Africa, what shape and colour identifies a warning sign?

Answer: Triangular with a red border (or diamond-shaped temporary)

Permanent warning signs are triangular with a red border on a white background. Temporary (roadworks) warning signs are diamond-shaped with a yellow background.

A regulatory sign reads 'R310' on a triangular plate with a red border and shows a speed in a red circle. What kind of sign sets the maximum speed?

Answer: A red-bordered circular sign with a number

Maximum speed limits are shown on a circular sign with a red border and a black number. For example, a '60' in a red circle means 60 km/h is the limit.

What is the danger of combining alcohol with prescription tranquilisers or sleeping pills and then driving?

Answer: The combined effect is far more impairing than either substance alone

Alcohol combined with sedative medications has a synergistic (multiplied) effect, causing much greater impairment than either substance by itself.

What should you do if you feel drowsy while driving on a long trip?

Answer: Stop at a safe place, rest or sleep before continuing

The only safe response to drowsiness is to stop, rest or sleep; other methods are temporary and do not restore alertness adequately.

On which side of the road do you drive in South Africa?

Answer: The left-hand side

In South Africa you drive on the left-hand side of the road and overtake on the right under normal conditions.

What does a steady amber (yellow) robot mean?

Answer: Stop if you can do so safely; the signal is about to turn red

A steady amber means the red is coming. You must stop if you can do so safely. Only proceed if you are too close to stop safely.

Before a long journey, a defensive driver should check what on the vehicle?

Answer: Tyres, lights, brakes, oil, water and indicators

A pre-trip check of tyres, lights, brakes, oil, water and indicators helps prevent breakdowns and keeps the vehicle roadworthy and safe.

What does a blue circular sign showing a white arrow pointing up mean?

Answer: Proceed straight ahead only (command)

Blue circular signs are command (mandatory) signs. A white upward arrow on blue instructs you that you must proceed straight ahead.

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

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.

If a traffic officer suspects you of drunk driving, which tests may legally be conducted?

Answer: A breath test, and if necessary a blood test

Under the National Road Traffic Act, an officer may conduct a breath test roadside and, if needed, require a blood test to confirm the result.

How does alcohol primarily affect a driver's ability?

Answer: It reduces reaction time and impairs judgement

Alcohol slows reaction time, impairs judgement, reduces coordination, and distorts perception, all of which are critical for safe driving.

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

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.

What does a warning sign showing a symbol of slippery road (a car with wavy skid lines) tell you?

Answer: The road may be slippery when wet

The slippery road sign warns that the surface may be slippery, especially when wet. Slow down and avoid sudden braking or steering.
