What action should be taken before beginning a turn regarding traffic?

Performing a traffic check for pedestrians and other objects before beginning a turn is essential for ensuring the safety of all road users. This action involves scanning the environment for any potential hazards, including people crossing the street, cyclists, or other vehicles that may not be immediately visible.

By conducting a thorough check, drivers can identify anything that could obstruct the turn or create a dangerous situation, allowing them to make informed decisions about when and how to execute the turn safely. This practice enhances awareness, reduces the risk of collisions, and contributes to a safer driving environment.

Neglecting to look for pedestrians and other objects, as suggested in the other options, compromises safety and can lead to accidents. Checking for nearby vehicles alone can cause drivers to overlook pedestrians or cyclists who may be in the vicinity. Moreover, focusing on a phone for maps creates significant distraction and diverts attention from the critical task of observing the road and surrounding environment.
