What must an operator do when emerging from an alley, driveway, or building?

When emerging from an alley, driveway, or building, the operator must stop and yield the right-of-way to pedestrians or vehicles. This is essential for ensuring the safety of pedestrians who may be crossing in front of the exit, as well as for vehicles that may be traveling on the road. By stopping and yielding, the operator allows for a clear view of the road and any incoming traffic, which helps in making a safe decision to proceed. This also adheres to traffic laws that prioritize the safety of all road users and prevents potential accidents that could occur due to hasty or careless maneuvers.

Practicing caution and yielding not only demonstrates responsible driving but also contributes to the overall safety and harmony on the road.
