Final answer:
When on a one way street with parked vehicles on the left, position your car towards the right side of your lane to maintain a safe distance from the parked vehicles and ensure safety.
Step-by-step explanation:
When driving on a one way street past vehicles parked on the left, you should position your car to the right portion of your lane. This practice allows for a safety buffer between your car and the parked vehicles, minimizing the risk of accidents if a car door is opened or if a pedestrian is hidden between parked cars. Always ensure to maintain a safe distance from the vehicles and adhere to traffic laws and road conditions.
