When must you use your turn signals when driving?

Using turn signals is essential for communicating your intended actions to other drivers and ensuring road safety. The correct requirement is to signal at least 100 feet before turning. This distance gives other drivers ample time to react to your maneuver, whether you're making a turn or changing lanes.

By signaling in advance, you're providing a clear indication of your intentions, which helps prevent accidents and keeps traffic flowing smoothly. It allows others to anticipate your movements, making it easier for them to adjust their speed or position accordingly.

The other options either suggest shorter distances or limited circumstances for signaling, which do not meet the standard for safe driving practices. Proper signaling is a crucial aspect of road safety and requires adequate warning time for other motorists.
