Final answer:
U-turns can be dangerous because they involve making a 180-degree turn across oncoming traffic. To mitigate risk, practice defensive driving techniques and obey traffic laws and signals.
Step-by-step explanation:
U-turns can be dangerous because they involve drivers making a 180-degree turn across oncoming traffic. This puts the driver and other vehicles at risk of collision. The danger of U-turns is particularly heightened in high-speed areas or intersections with limited visibility.
To mitigate the risk of other drivers making U-turns, you can practice defensive driving techniques. This includes being alert and aware of your surroundings, maintaining a safe following distance, and anticipating the actions of other drivers. Additionally, it is important to obey traffic laws and signals, as they provide guidance for safe driving.
