When driving at speeds of 45 mph or higher, when should you turn on your turn signal before making a turn?

When driving at speeds of 45 mph or higher, it is important to turn on your turn signal at least 100 feet before making a turn. This distance allows other drivers and pedestrians adequate time to notice your intention to turn, which enhances safety on the road. Signaling well in advance gives fellow motorists a chance to react appropriately, whether that means adjusting their speed, changing lanes, or preparing to stop.

Turning on your signal too close to the turn could result in confusion or unexpected maneuvers from other drivers, increasing the risk of an accident. It's vital for drivers to understand the importance of signaling in ensuring the safety and smooth flow of traffic, especially at higher speeds where reaction times are critical.
