What should be done if a driver is unsure whether to change lanes?

When a driver is unsure about whether to change lanes, the appropriate response is to check mirrors and signal before attempting the maneuver. This approach ensures that the driver is fully aware of their surroundings and can confirm whether the lane change is safe.

Checking mirrors allows the driver to see if there are any vehicles in the blind spots and assess the traffic situation around them. Signaling communicates the intention to other road users, which is critical for maintaining road safety. This practice not only reduces the risk of collisions but also promotes a more predictable driving environment for everyone on the road.

Adopting this method reflects good defensive driving strategies and enhances overall road safety.
