When angle parking, the driver begins steering when _____.

The correct response is based on the principle that effective angle parking requires proper timing in steering to facilitate a smooth and safe entry into the parking space. Steering the vehicle when the steering wheel is aligned with the first line of the space allows the driver to accurately gauge the angle necessary to enter the spot correctly without encroaching into adjacent spaces.

When the driver aligns the steering wheel with the first line of the parking space, they are establishing the correct trajectory and angle needed for the vehicle to fit into the space securely. This timing helps ensure the vehicle enters the space at an appropriate angle, minimizing the risk of hitting curbs or other vehicles.

Option variations, such as waiting until the vehicle is fully in the space, the rear tires cross a line, or the front bumper is clear of another vehicle, do not provide adequate orientation for the driver to maneuver effectively into the parking space. These approaches could lead to a less controlled entry, potentially increasing the risk of collision or improper parking. Thus, the best practice is to begin steering when the wheel is aligned with the first line of the space, ensuring a safe and efficient parking process.
