Why is a larger following distance needed at motorway speeds?

101. Why is a larger following distance needed at motorway speeds?

✓ You need more distance to react and stop safely.
It makes the vehicle easier to steer.
It keeps the engine from working too hard.
It prevents the tyres from becoming too warm.

At higher speeds, you travel farther during your reaction time and need more distance to brake. A larger gap gives you more time and space to stop safely.

102. How should cyclists cross railway or tram tracks?

Keep the wheels parallel with the rails while crossing.
Brake firmly while the front wheel is on the rail.
Increase speed so the wheels cannot get caught.
✓ Cross at a safe angle, as close to perpendicular as possible.
