What is the proper distance to use your turn signal before making a turn?

Using your turn signal 100 feet prior to making a turn is important for ensuring safety on the road. This distance provides adequate time for other drivers and pedestrians to notice your intention to turn. When you signal ahead of time, it allows others to anticipate your movement, helping to prevent collisions and maintain smooth traffic flow.

In many jurisdictions, including Texas, the 100-foot guideline is a standard practice that has been established to promote driver awareness and communication on the road. Proper signaling reinforces the principle of cooperation among drivers, ensuring that everyone is aware of each other's actions well in advance. This distance gives other road users a chance to react appropriately, whether that means slowing down, changing lanes, or preparing for a stop.

When considering the other distances, they may not offer the same level of notification. Shorter distances, like 50 feet, may not give sufficient time for other drivers to respond, while excessively long distances, such as 200 or 300 feet, could be unnecessary and lead to confusion on the road. Thus, signaling at 100 feet strikes a balance between being timely and sufficiently informing those around you about your planned actions.
