What should a driver do before shifting an automatic transmission from "neutral" to "drive"?

Before shifting an automatic transmission from "neutral" to "drive," it is essential for the driver to press on the brakes with their right foot. This action ensures that the vehicle remains stationary and avoids any unintended movement that could occur when the gear is changed. Engaging the brakes provides a safety mechanism that helps prevent accidents and maintains control of the vehicle during the shifting process.

Releasing the parking brake is important when preparing to drive, but it should only be done after the transmission is in the appropriate gear. Pressing the horn or turning on the headlights are unrelated to shifting gears and do not have any bearing on the safe operation of the vehicle during this specific action. The focus on engaging the brake before shifting highlights the importance of maintaining control and prioritizing safety while driving.
