What this topic is really about
Dim high beams at least 150 metres before meeting an oncoming vehicle at night to avoid dazzling the other driver.. Drivers must lower high beams to low beams before they get close enough to dazzle an oncoming driver, generally at least around 150 metres away.
The safest following distance is at least a two-second gap, which should be increased in poor driving conditions.. The two-second rule gives you enough time and space to react and stop safely behind the vehicle ahead in good conditions.

An exam-style question, fully explained
What is the safest following distance to maintain behind the vehicle ahead under good driving conditions?
- Identify what the question tests: What is the safest following distance to maintain behind the vehicle ahead under good driving conditions.
- The two-second rule gives you enough time and space to react and stop safely behind the vehicle ahead in good conditions.
- In rain, snow, or fog the gap should be increased to four seconds or more because stopping distances grow.
- Why it matters: The two-second rule provides enough time and space to react and stop safely behind the vehicle ahead in good conditions. In poor conditions such as rain, snow, or fog, the stopping distance increases, so the following distance should be increased to four seconds or more. This allows for a safe stopping time and reduces the risk of accidents.
Traps the examiner sets
- Many drivers underestimate the importance of following distance and often tailgate, which can lead to accidents. Others may not adjust their following distance according to the driving conditions, which can also be hazardous.
- Many drivers mistakenly believe that idling to keep the engine warm or driving above the speed limit on highways is more efficient, but in reality, these habits increase fuel consumption and emissions.
- Some drivers may believe that they only need to dim their high beams when the oncoming vehicle is very close or when the other driver flashes their lights, but this can be too late and may still cause discomfort or hazards.
- High beams should also be dimmed when following closely behind another vehicle to avoid blinding that driver through their mirrors.
