What should you do before putting the key in the ignition?

Before putting the key in the ignition, ensure you're seated comfortably in the driver's seat with your seatbelt fastened. Check that the gear is in "Park" (for automatic transmissions) or "Neutral" (for manual transmissions). Additionally, take a moment to adjust your mirrors and verify that all doors are closed and secure. This preparation helps promote safety and readiness for driving.
