502. What should cyclists do when approaching a junction?

✓ Reduce speed, observe carefully, and be ready to stop.
Watch only the traffic directly ahead of you.

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

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

It affects reaction distance but not braking distance.
It affects braking distance only on wet roads.
It has no effect if the brakes are in good condition.
✓ It increases the distance needed to stop.

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.

Why should you avoid driving through deep water?

506. Why should you avoid driving through deep water?

Water causes the tyres to lose air pressure.
Deep water makes the engine use too much oil.
Increase speed to maintain full control through the water.
✓ It can damage your vehicle or make you lose control.

Deep water can damage the engine, reduce braking ability, hide hazards, or cause the vehicle to lose grip. Reduce speed, assess the depth and conditions carefully, and avoid entering the water if you are unsure it is safe. If necessary, stop and use another route.

Why should you avoid using a phone while driving?

509. Why should you avoid using a phone while driving?

✓ Because it distracts you from the road.
Because it can make your reactions faster.
Because phone signals can interfere with vehicle electronics.
Because it can cause road rage.

Using a phone while driving reduces attention, reaction time, and control of the vehicle. A hands-free system may reduce the need to handle the phone, but the conversation itself can still be distracting.

How should you normally brake on a motorcycle?

518. How should you normally brake on a motorcycle?

Use only the front brake.
Alternate between the front and rear brakes.
✓ Use both brakes smoothly and progressively.
Use only the rear brake.

During normal braking, use both the front and rear brakes smoothly and progressively. The front brake normally provides much of the braking force, while the rear brake also helps slow and stabilise the motorcycle. Sudden or poorly balanced braking can reduce stability or cause a wheel to lose grip.

Why should a seat belt not be twisted when worn?

519. Why should a seat belt not be twisted when worn?

✓ A flat belt spreads collision forces more effectively.
A flat belt makes the seat easier to adjust.
A twisted belt can cause the buckle to open.
A twisted belt prevents the airbags from working.

A seat belt should lie flat against the body without twists. A twisted belt concentrates force over a smaller area and may provide less effective protection in a collision.
