Question: 1 / 400

What is the required distance to signal when changing lanes?

At least 2 seconds before changing

At least 3 seconds before changing

At least 5 seconds before changing

The required distance to signal when changing lanes is at least 5 seconds before making the maneuver. This practice is designed to provide ample time for other drivers to see your intention to change lanes and react accordingly. Signaling in advance creates a safer driving environment by reducing the risk of collisions, as other road users will have the opportunity to adjust their speed or position in response to your signal.

A 5-second signaling duration not only gives other drivers an adequate opportunity to notice the signal but also allows you, as the driver, to properly assess the road and the behavior of surrounding vehicles before executing the change. This timeframe enhances situational awareness and promotes more predictable and safer driving behaviors on the roadway.
