Traffic Laws and Regulations: Signals, Priority, Speed, and Alcohol
What this domain tests
The traffic-law section of the Class 1 written test checks whether you can apply the Road Traffic Act at everyday junctions, not just recall signs. Expect signal meanings, right-of-way, speed limits, alcohol thresholds, and child-protection zones.
Signals and priority
- A steady yellow light means stop before the stop line unless you are too close to stop safely.
- A flashing yellow means slow down and yield; a flashing red means stop, then proceed only when clear.
- Unprotected left turns are made on a green light only after yielding to oncoming traffic and pedestrians.
- At a roundabout, vehicles entering yield to vehicles already circulating.
- A right turn on red requires a full stop and yielding to pedestrians and cross traffic; follow any right-turn signal or prohibition sign.
Speed and alcohol
Urban roads are generally 50 km/h, child-protection zones 30 km/h, and expressways 100 km/h. A blood-alcohol level of 0.03% brings licence suspension; 0.08% brings revocation.
Worked example
You approach a roundabout and a car is already circling from your left. You want to enter. Because the circulating car has priority, you slow and stop at the yield line, then enter only after it passes. Trying to beat it is both a test fail and a real-world collision pattern.
Traps that cost marks
Do not treat flashing yellow as go - it is a warning to slow and give way. Do not assume a right turn on red is always allowed. Do not mix up the 0.03% suspension and 0.08% revocation thresholds. Child zones are 30 km/h, not the ordinary urban 50 km/h.
