Final answer:
A vehicle entering a street from a private area must yield to both vehicles and pedestrians, stopping until it is safe to go on to prevent accidents and ensure safety.
Step-by-step explanation:
A vehicle entering a street from a private alley or driveway must yield to approaching vehicles and pedestrians. This means that the vehicle should stop moving and become stationary until it is safe to proceed. This rule helps to ensure the safety of all road users by preventing accidents that can occur when drivers do not respect the right-of-way of pedestrians and other vehicles.
It is also essential to consider the role of traffic signals, as they are instrumental in managing the flow of both vehicles and pedestrians. A traffic signal at a busy intersection ensures that vehicles do not speed through and that pedestrians can cross at appropriate times without having to dodge traffic, thus greatly enhancing pedestrian safety.
