How many feet must you signal before turning or changing lanes?

To ensure safety and compliance with traffic regulations, drivers in Illinois are required to signal at least 100 feet before turning or changing lanes. This distance provides adequate time for other drivers and pedestrians to notice your intentions, allowing them to react appropriately. Signaling effectively helps to prevent accidents and enhances overall road safety. It's essential for maintaining clear communication with other road users, as it reduces uncertainty about your next move on the road. Adhering to this rule is part of responsible driving practices that contribute to a safer driving environment for everyone.
