What is a Road Hazard?

A hazard is anything in surface of the road which is likely to be dangerous or cause an accident. A hazard does not need to be large to be dangerous: even a small crack can be dangerous to a cyclist with skinny wheels.

Road hazards can be physical defects in the carriageway, such as potholes, sunken manhole covers and cracks in the tarmac, to more temporary hazards like spilt oil or gravel.
