What should a driver do upon activation of the open compartment door sensor?

When the open compartment door sensor is activated, it indicates that a door may be unlatched or open, which poses a significant safety risk while driving. The correct action is to reapply the parking brake and safely exit the unit cab. By securing the vehicle with the parking brake, the driver ensures that it will not roll or cause any accidents while attending to the alert. Exiting the cab allows the driver to assess the situation closely and ensure that all doors are properly secured before continuing to operate the vehicle.

This practice not only guarantees the safety of the driver but also ensures that nothing falls out of the open compartment during transit, which could lead to further hazards on the road. Addressing the issue immediately helps to maintain operational safety and vehicle integrity.
