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

Signaling at least 100 feet before making a turn is crucial for road safety and communication with other drivers. This distance allows sufficient time for other motorists, pedestrians, and cyclists to anticipate your intentions, promoting smoother traffic flow and reducing the risk of accidents.

When you signal in advance, it gives following vehicles time to react and adjust their speed or position as necessary. This practice is part of safe driving etiquette, ensuring that everyone on the road is aware of your actions and can make informed decisions based on your signal.

While some contexts may call for signaling at varying distances depending on speed and road conditions, the 100 feet rule is a widely accepted standard that balances safety and practicality in urban driving environments.
