Final answer:
The driver can turn their vehicle and proceed in the opposite direction where legally permitted, such as at designated U-turn areas or traffic signals that specifically allow such turns. It is crucial to follow all traffic laws and signs, and to ensure the safety and legality of the maneuver.
Step-by-step explanation:
The driver may turn their vehicle and proceed in the opposite direction at intersections where U-turns are legally permitted, in areas with a designated turning zone, or when it is safe to do so without disrupting the flow of traffic. It is important to always follow traffic signals and signs, and to ensure that performing such a maneuver is not prohibited. For example, at a traffic signal, if the signal permits a U-turn with a corresponding sign or green arrow pointing in the direction of the turn, the driver can safely make the turn. In contrast, executing a U-turn at an intersection with a high speed limit or poor visibility might be illegal and dangerous. Moreover, certain states and municipalities have specific laws and regulations about where and when a vehicle can turn to proceed in the opposite direction, often depending on the type of road, presence of a median, or other factors.
