What should drivers do when passing another vehicle?

Answer: C — Use a turn indicator

When passing another vehicle, it is crucial for drivers to use a turn indicator to signal their intention. This practice ensures clear communication with other road users, indicating that you intend to move into another lane. Proper signaling is a fundamental aspect of safe driving, as it allows other drivers to anticipate your actions, contributing to overall road safety. By using a turn indicator, you demonstrate awareness of your surroundings and promote a cooperative driving environment. In scenarios where signaling is not employed, there can be confusion and potential accidents, as other drivers may not realize you are attempting to pass. This could lead to dangerous situations if they misjudge your speed or trajectory. Therefore, using a turn indicator not only adheres to legal requirements but also promotes safer driving practices.
