What is the safest way to carry items inside the car?

Place them in a secure location
Place them on the floor near the driver's feet

The safest way to carry items in a vehicle is to place them in a secure location, such as the trunk or a fixed storage compartment. Placing items on the rear shelf, on the driver's lap, or on the floor near the driver's feet can be dangerous, as these items may shift or fly around during sudden braking or in an accident, posing a safety risk.
