How should cyclists brake on a wet road?

251. How should cyclists brake on a wet road?

Brake sharply once you are close to stopping.
Brake later and more firmly than usual.
✓ Brake earlier and more gradually than usual.
Brake normally because wet roads do not affect grip.

Wet surfaces reduce grip and increase stopping distance. Smooth, early braking helps prevent skidding.

What should you do before overtaking while towing a trailer?

252. What should you do before overtaking while towing a trailer?

Follow closely before moving out to overtake.

Assume the trailer will follow the same path as the vehicle.
✓ Allow extra time and distance for the manoeuvre.

A towing vehicle accelerates more slowly, and the trailer makes the whole vehicle combination longer. Remember to allow a much larger safe gap before overtaking and enough space to return safely to your lane.
