When should a driver use their turn signals?

Answer: C — Every time before turning or changing lanes

Using turn signals is essential for safe driving, as they communicate a driver's intentions to other road users. A driver should use their turn signals every time before turning or changing lanes to ensure that other drivers, cyclists, and pedestrians are aware of their intended actions. This helps to reduce the risk of accidents and enhances overall roadway safety by promoting clear and predictable behavior among all road users. Unlike the other options, which restrict the use of turn signals to specific situations or deem them optional, this choice emphasizes the importance of signaling in all relevant circumstances. Consistent use of turn signals aids in creating a safer driving environment by providing everyone on the road with clear information about the driver's actions.
