When are you required to use your turn signal when changing lanes?

Using a turn signal at least 100 feet before changing lanes is mandated because it provides adequate warning to other drivers and increases overall road safety. This advance notice allows nearby vehicles to anticipate your movement and react accordingly, which is particularly important in maintaining safe distances and avoiding collisions.

In general, signals are vital for communicating your intentions on the road. By signaling well in advance, you’re helping to create a predictable driving environment, which benefits everyone. Although there may be scenarios where changing lanes may seem safe without immediate warning to other drivers, adhering to the 100-foot rule cultivates responsible driving behavior and reinforces the importance of signaling in various situations.
