New Zealand Car Driving Driving in Hazardous Conditions Questions and Answers — Questions and Answers
Question 1: You are driving on a motorway during a heavy downpour and your car begins to hydroplane, losing contact with the road surface. What is the most appropriate immediate action to take?
- Brake firmly and steer hard towards the shoulder.
- Accelerate slightly to try and power through the water.
- Ease your foot off the accelerator and steer gently where you want to go. (Correct answer)
- Turn the steering wheel quickly from side to side to regain grip.
Correct answer: Ease your foot off the accelerator and steer gently where you want to go.
When hydroplaning, sudden actions like hard braking or sharp steering can cause a complete loss of control. The correct procedure is to ease off the accelerator to allow the car to slow down naturally and for the tyres to regain contact with the road, while making only small, gentle steering corrections.
Question 2: The standard two-second following distance is recommended for good conditions. According to the NZ Road Code, what is the MINIMUM following distance you should use when driving in heavy rain or on a frosty morning?
- The two-second rule is sufficient for all conditions.
- It should be increased to at least a four-second rule. (Correct answer)
- It should be decreased to a one-second rule to see the vehicle ahead better.
- It should be increased to a three-second rule.
Correct answer: It should be increased to at least a four-second rule.
In hazardous conditions like rain or frost, stopping distances are significantly longer. The NZTA Road Code explicitly recommends doubling the following distance from two seconds to at least four seconds to provide a safe buffer for reacting and braking.
Question 3: You are driving on a cold, clear winter morning. Which of the following locations is most likely to have hazardous black ice?
- A busy intersection in the middle of the city.
- A section of road exposed to direct, bright sunlight.
- The surface of a bridge or an overpass. (Correct answer)
- A straight, flat section of a main highway.
Correct answer: The surface of a bridge or an overpass.
Black ice is a thin, transparent layer of ice that forms on road surfaces. Bridges and overpasses are particularly prone to black ice because cold air circulates both above and below the road surface, causing it to freeze faster and stay frozen longer than the ground-level road.
Question 4: When driving in dense fog during the daytime, which lights should you use to ensure you can be seen by other drivers without reducing your own vision?
- Headlights on high beam.
- Hazard warning lights.
- Parking lights only.
- Headlights on dipped (low) beam. (Correct answer)
Correct answer: Headlights on dipped (low) beam.
In foggy conditions, high-beam headlights will reflect off the water droplets in the air, creating glare and severely reducing your visibility. Dipped (low) beam headlights are aimed downwards, illuminating the road ahead and making you visible to others without causing this reflection.
Question 5: You are driving at sunrise and are suddenly affected by severe sunstrike, making it almost impossible to see the road ahead. What is the safest course of action?
- Turn on your headlights and continue at a reduced speed.
- Follow the tail lights of the car in front of you very closely.
- Speed up to get through the affected area as quickly as possible.
- Signal, pull over to a safe position on the left, and stop until your vision improves. (Correct answer)
Correct answer: Signal, pull over to a safe position on the left, and stop until your vision improves.
If you are blinded by sunstrike and cannot see the road, continuing to drive is extremely dangerous. The safest action is to slow down, signal, and pull over to a safe place to stop until your vision clears or you can use your sun visor and sunglasses to mitigate the glare.
Question 6: When driving on a loose gravel (unsealed) road, how should you approach a sharp corner?
- Accelerate just before the corner to maintain momentum and grip.
- Brake firmly while turning to shift weight onto the front wheels.
- Slow down to a safe speed in a straight line before entering the corner. (Correct answer)
- Maintain your current speed but turn the steering wheel more sharply.
Correct answer: Slow down to a safe speed in a straight line before entering the corner.
On unsealed surfaces, traction is greatly reduced. All braking and speed reduction should be done smoothly and in a straight line before you reach the corner. Braking or accelerating while turning on gravel can easily cause the tyres to lose their grip, leading to a skid.
