§ 636. Entering or leaving alleys, driveways or buildings.

A.

The driver of a vehicle emerging from an alley, driveway or building shall stop such vehicle immediately prior to driving onto a sidewalk or onto the sidewalk area extending across any such alley or driveway and before proceeding onto the street shall see that such street and sidewalk is sufficiently free from moving vehicles or pedestrians to permit such vehicle to enter the line of moving vehicles without collision, yielding the right-of-way to vehicles and pedestrians which are so close as to constitute an immediate hazard.

B.

The driver of a vehicle turning into an alley or driveway shall not make such turn until the street from which such turn is being made is sufficiently free from moving vehicles and pedestrians to permit such turn without a collision. The driver making such turn shall yield the right-of-way to all pedestrians and vehicles already in motion on the street so close as to constitute an immediate hazard.
