Korean Driver's License Practice Test

Stopping, making U-turns, and backing up on expressways are prohibited due to safety concerns and the high-speed nature of these roadways. Expressways are designed for the efficient movement of traffic, and any unexpected stopping or maneuvering can lead to serious accidents, not only for the vehicle performing these actions but also for other drivers who may not anticipate such behavior. The prohibition is in place to ensure a continuous and fluid flow of traffic, allowing vehicles to travel at high speeds without the risk of encountering cars that are stopping or reversing. This increases the safety of all road users and reduces the likelihood of collisions. Other options suggest conditional allowances that could create dangerous situations on such high-speed roads, but the blanket rule is that these actions are not permitted at any time.
