Why can bridges and overpasses become icy before nearby roads?

272. Why can bridges and overpasses become icy before nearby roads?

Road salt is less effective on bridges.
Bridges are always at a higher altitude.
Their barriers trap cold air on the road surface.
✓ Cold air circulates above and below them.

Bridges lose heat from both their upper and lower surfaces, so they can freeze before roads built directly on the ground.

How should you normally brake on a motorcycle?

291. How should you normally brake on a motorcycle?

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