Final answer:
Stop the vehicle in an alley or driveway without obstructing traffic, having a clear view for safety, and not blocking the sidewalk when preparing to turn around.
Step-by-step explanation:
When heading into an alley or driveway on your left to turn around, the correct action to take once in the lane varies depending on the specific situation and surroundings. However, in general, it's important to stop the vehicle in a position where you do not obstruct traffic, have a clear view of oncoming vehicles, and can safely maneuver your car to complete the turn-around without posing a risk to yourself, pedestrians, or other drivers. Close attention to road signs, signals, and markings is also crucial. It's recommended that the driver stops far enough into the alley or driveway so that they are not blocking the sidewalk or pedestrian path, and to ensure that the vehicle's rear does not protrude into the lane it just left, posing a hazard to other road users.
