Which of the following is not a type of horizontal roadway curvature?
  1. Simple
  2. Compound
  3. Superelevated
  4. Reverse
Explanation
Answer: C - “Superelevated” is not a type of horizontal roadway curvature.

Superelevation is the practice of banking of a roadway curve to counterbalance the centrifugal force of a vehicle moving through the horizontal curve. Together with the side friction developed between a vehicle’s tires and the road surface, superelevation allows a vehicle to negotiate curves safely at higher speeds than if the roadway was not superelevated.
