What signal must be used for turns if a driver is within a specified distance from other vehicles?

Using turn signals is essential for informing other drivers and pedestrians of your intentions when making a turn. Turn signals indicate that you plan to change your direction, providing a clear warning to those around you about your movements. This communication is especially important when you are within a certain distance of other vehicles, as it allows them to adjust their speed or position accordingly, enhancing overall safety and reducing the likelihood of accidents.

While hand signals can also indicate turns, they are generally used in situations where electronic turn signals might not be functional or in areas where hand signals are more effective, such as biking. Road flares are used for emergency situations to alert others of a hazard, and car horns serve primarily as a warning device rather than a directional signal. Thus, employing turn signals is the best practice for ensuring clear communication on the road during turns.
