Final answer:
The minimum pavement width for a 180-degree turn depends on the turning radius of the vehicle being used.
Step-by-step explanation:
The minimum pavement width for a 180-degree turn depends on various factors, including the turning radius of the vehicle. Typically, the width of the pavement required for a 180-degree turn is equal to or slightly greater than the length of the vehicle being used. For example, if the average car width is 2 meters, then the minimum pavement width for a 180-degree turn would be around 4 meters.
