Show answer and explanation
Correct answer: design speed of a road.
When a road is planned, a speed is chosen and used to design the curves and sight distances for each section. That is the design speed, or planned speed: the highest speed you can safely maintain on that section when conditions are favorable. The appropriate speed also depends on rain, traffic, or your condition, and may be much lower.
