What is the main factor in the cause of accidents?
A)The state of the road.
B)The state of conservation of the vehicle.

The person is the predominant factor in the production of accidents, because if the road is not in perfect condition or the vehicle has some problem, the driver must adapt to those unfavourable circumstances. Fog or heavy rain, for example, will not be considered the cause of an accident, since the driver should have adapted his driving to these circumstances.
