✓ To prevent it from suddenly running into the road.
To make it easier for drivers to hear the dog.
To make approaching vehicles drive more slowly.
To give the dog priority when crossing the road.

Dogs can react unpredictably to vehicles, people, noises, or other animals. Keeping a dog under close control on a leash near traffic reduces the risk of it suddenly entering the road and endangering itself or other road users.

How should you normally brake on a motorcycle?

128. How should you normally brake on a motorcycle?

✓ Use both brakes smoothly and progressively.
Use only the rear brake.
Apply both brakes as suddenly as possible.
Use only the front 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 hard braking be avoided while a motorcycle is leaning in a bend?

132. Why should hard braking be avoided while a motorcycle is leaning in a bend?

It can make the engine overheat.
It prevents the suspension from working.
✓ It can reduce stability and available tyre grip.
It makes the motorcycle turn more sharply.

When a motorcycle is leaning, the tyres are already using grip to turn. Hard braking can demand additional grip and may reduce stability. Whenever possible, adjust speed before the bend and use smooth, controlled inputs while cornering.

They can increase the motorcycle's braking power.
✓ They can provide much less grip than the surrounding road.
They can make the suspension become stiffer.
They can make the tyres overheat.

Wet metal surfaces, such as drain or inspection covers, can provide much less grip than the surrounding road. Cross them smoothly, keep the motorcycle as upright as practical and avoid sudden braking, acceleration or steering.
