What is road camber?
- A The anti-slip road surface used near some hazards
- B The way the road surface slopes to help drainage
- C The measure of the steepness of a hill
- D The measure of the sharpness of a bend
Why this is the answer
Usually, a road is constructed with a camber: the road surface slopes to assist with drainage. Some bends have an 'adverse camber'. This is where the road slopes towards the outside of the bend. When going around a bend that has adverse camber, you need to take extra care. The forces acting on your vehicle could cause it to leave the road more easily than normal.
Why the other answers don't fit
- A
- The anti-slip road surface used near some hazards — Anti-skid surfacing is laid for grip, which is a different thing entirely.
- C
- The measure of the steepness of a hill — Steepness is the gradient, measured as a percentage.
- D
- The measure of the sharpness of a bend — Sharpness is the radius of a bend.
