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 road's geometry based on safety and comfort criteria. It represents the intended safe speed for the section under favorable conditions, not the permitted speed limit.
