Georgia Commercial Driver License Practice Test

The correct action for a driver needing to change lanes is to signal and check mirrors and blind spots first. This is crucial for ensuring safety on the road. Signaling not only informs other drivers of your intentions but also aligns with traffic laws requiring drivers to communicate their movements. Checking mirrors allows the driver to see vehicles that may be in adjacent lanes, while checking blind spots ensures that no obstacles or vehicles are present in areas not visible in the mirrors, thereby reducing the risk of collisions during the lane change. By performing these actions, the driver can make informed decisions about when it is safe to change lanes, promoting safety for both themselves and other road users. Neglecting these steps could lead to dangerous situations, such as side-swiping another vehicle or causing confusion among other drivers.
