Question

The design speed of road is ____ percentile speed.

• A. 85\textsuperscript{th}
• B. 50\textsuperscript{th}
• C. 98\textsuperscript{th}
• D. 80\textsuperscript{th}

Hint:

For road design, always use the 98\textsuperscript{th} percentile speed to ensure that most drivers can safely navigate the road.

Answer 1

The Correct Option is C

The design speed of a road is generally based on the **98\textsuperscript{th}** percentile speed, which ensures that the road is designed for the speed at or below which 98% of drivers will be traveling. This is to accommodate typical driving behavior while ensuring safety.
