A vehicle is travelling at an inappropriate speed when...
A)it does not adapt to the circumstances of either the traffic or the road.Correct
B)it adapts to the road conditions but exceeds the established limits.
C)it travels below the maximum speed and above the minimum.
When we drive at a speed that is not adapted to the weather conditions or the circumstances of the road, traffic, vehicle or to the driver's conditions, we will be travelling at an inappropriate speed.
It may be that the speed at which we are travelling is within the limits permitted for the road but, in the face of a problematic situation, we have great difficulty in controlling the vehicle. For example, on rainy days more accidents tend to occur because many drivers travel at the same speed as on a sunny day, that is, they travel at a permitted but inappropriate speed on rainy days.
