What should you do when driving through heavy rain?

552. What should you do when driving through heavy rain?

✓ Reduce speed and increase your following distance.
Accelerate through the rain to clear it more quickly.
Use main beam to improve visibility.
Drive closer to the vehicle ahead for guidance.

Why does higher speed increase the risk of aquaplaning?

556. Why does higher speed increase the risk of aquaplaning?

The vehicle becomes heavier as speed increases.
The suspension becomes less effective at high speed.
The brakes cannot remove water from the tyres.
✓ The tyres have less time to clear water from the road surface.

At higher speeds, the tyres may not disperse water effectively, making it easier for the vehicle to lose contact with the road.

What should you consider before selecting a lower gear in a manual vehicle?

565. What should you consider before selecting a lower gear in a manual vehicle?

Whether the parking brake is applied.
Whether the steering wheel is centred.
Whether the headlights are switched on.
✓ Whether the vehicle's speed is suitable for the lower gear.

✓ No, they may only increase alertness temporarily.
Yes, if the journey is less than one hour.
Only coffee can replace proper rest.
Yes, if you use several of them together.

Coffee, energy drinks, fresh air, or loud music may make you feel more alert for a short time, but they do not remove fatigue. If you are too tired to drive safely, stop somewhere safe and get proper rest.

Why should an unused roof rack or roof box be removed?

572. Why should an unused roof rack or roof box be removed?

It reduces the vehicle's braking power.
It prevents the battery from charging.
✓ It can increase aerodynamic drag and energy use.

Why must you take wider turns when towing a trailer?

574. Why must you take wider turns when towing a trailer?

Wide turns prevent the trailer from swaying.
Wider turns reduce the trailer's stopping distance.
Wider turns decrease tyre wear.
✓ The trailer follows a tighter path than the towing vehicle.

Trailer wheels cut closer to the inside of a turn. Allow enough clearance from kerbs, signs, pedestrians, and other vehicles.

How does higher speed affect a vehicle's stopping distance?

578. How does higher speed affect a vehicle's stopping distance?

✓ It increases the distance needed to stop.
It affects braking distance only on wet roads.
It decreases the distance needed to stop.
It affects reaction distance but not braking distance.

As speed increases, the vehicle travels farther while the driver reacts and requires more distance to brake. This means the total stopping distance increases significantly as speed rises.
