Question

u - turns are permitted in an urban area in the following locations: select one: a. on a curve in the road b. none of these c. at an intersection controlled by a traffic signal d. on a roadway between intersections

Explanation:

U-turns on a curve (option a) are dangerous due to limited visibility and are not permitted. U-turns between intersections (option d) are generally prohibited in urban areas as they disrupt traffic flow. While some signal-controlled intersections allow U-turns, it is not a universal rule, and the other options are clearly invalid. Since none of the specific permitted location options are universally correct, the appropriate choice is "None of these".

Answer:

b. None of these
