How far in advance must you signal before making a turn?

Signaling at least 100 feet before making a turn is important for several reasons. This distance provides adequate warning to other drivers and pedestrians about your intended maneuver, allowing them to adjust their actions accordingly. It ensures that those around you are aware of your intention, which contributes to safer driving conditions.

In urban environments or when driving at higher speeds, this guideline gives following drivers enough time to react, potentially preventing collisions. Adequately signaling also demonstrates responsible driving behavior, as it fosters communication between road users, enhancing overall traffic safety.

While other options suggest various distances, the 100-foot requirement strikes a balance between safety and practicality, making it the standard in many driving regulations, including those in Idaho.
