Question 826
The design speed of a road is…
- The maximum safe speed that can be maintained on a section of road under favorable conditions.
- The permitted speed limit.
- A speed inappropriate for the conditions.
Show answer and explanation
Correct answer: The maximum safe speed that can be maintained on a section of road under favorable conditions.
Design speed is used to define the geometry of the road alignment and serves as a reference for safe travel under favorable conditions. It is not the same as the permitted speed limit.
