What must you do when entering a street from a private alley or driveway?

When entering a street from a private alley or driveway, it is essential to stop and yield to approaching vehicles and pedestrians. This action helps to ensure safety for all road users. Since visibility might be limited when exiting an alley or driveway, stopping allows you to assess the traffic conditions properly before merging onto the street. It is important to check for oncoming vehicles or pedestrians who may have the right of way, ensuring that you do not create a hazardous situation. This practice helps minimize the risk of accidents and promotes safe driving habits.

The other options suggest approaches that could lead to dangerous situations, such as not stopping to check for traffic or pedestrians, which could result in collisions or injuries. Failing to yield can cause confusion and danger to yourself and others on the road.
