How far in advance should you signal before turning?

Signaling at least 100 feet before making a turn is essential for safe driving as it provides adequate warning to other drivers and road users about your intended action. This distance allows following vehicles to react properly, reducing the likelihood of collisions. It ensures that your signal is visible and noted by others, allowing them enough time to adjust their speed or position accordingly.

In many jurisdictions, the 100-foot guideline strikes a balance between being early enough for safety while not being overly excessive that it confuses other drivers. This practice is aligned with safe driving principles focusing on giving clear, early warnings. Proper signaling shows good driving etiquette and helps maintain the flow of traffic without sudden stops or unexpected maneuvers.
