Why is adequate tyre tread important?

402. Why is adequate tyre tread important?

✓ It helps maintain grip and move water away from the tyre.
It increases the amount of power from the engine.
It prevents tyres from losing air pressure.
It makes wheel alignment unnecessary.

Tyre tread helps the vehicle grip the road and disperse water. Worn tread increases the risk of skidding and aquaplaning, especially in wet conditions.

Why should you leave extra space when following a large vehicle?

405. Why should you leave extra space when following a large vehicle?

To prevent the large vehicle from changing lanes.

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

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

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

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.
