What should you do if you plan to turn left at an intersection?

When planning to turn left at an intersection, it's essential to first signal your intention to let other drivers and pedestrians know your plans. This promotes safety and helps prevent accidents, as it alerts others to your upcoming actions. After signaling, you should check for pedestrians crossing and ensure there is no oncoming traffic. It is crucial to wait for a safe gap in the oncoming vehicles before making the turn.

This response incorporates important aspects of safe driving practices, emphasizing the need for signaling and confirming the safety of the intersection before proceeding. It's a comprehensive approach that prioritizes both the driver's and other road users' safety, which is vital in avoiding collisions.

In contrast, the other approaches lack significant precautions. Merely signaling and turning immediately does not account for pedestrian or vehicle presence. Checking a map should be done before reaching the intersection, not during the turn, as it can distract from safely navigating the road. Stopping and looking without signaling can confuse other drivers and doesn't inform them of your intentions. Thus, the first option encompasses all necessary steps required for a safe left turn.
