When leaving a driveway, what must the driver do?

When leaving a driveway, it is essential for a driver to stop before crossing any sidewalk area and yield to all traffic. This is crucial for ensuring the safety of pedestrians who may be using the sidewalk, as well as for observing any vehicles that could be approaching or passing on the road.

Yielding means giving the right of way to both pedestrians and vehicles that are already on the road to avoid any potential accidents. By stopping before crossing the sidewalk, the driver can check for any pedestrians, bicycles, or other vehicles that may not be immediately visible, especially in situations where visibility is limited.

While other options may imply taking caution, they don't encompass the full requirement of yielding and stopping when leaving a driveway, which is specifically designed to ensure the safety of both the driver and others in the vicinity.
