A warning system for vehicles equipped with air brakes is provided. The present invention provides one or more warning modules in connection with a low pressure switch and a door jamb switch to provide an alert if the driver fails to apply the parking brake and opens the vehicle door. A low pressure switch is connected to an air line controlled by a cabin parking brake switch. When the parking brake switch is toggled on, air is evacuated from the air line and the parking brakes are applied; the low pressure switch is then open. When the air line is pressurized, the parking brake switch is not toggled on and the parking brakes are not applied, causing the low pressure switch to close. If the door jamb sensor registers the driver door is open, the low pressure switch and door jamb sensor complete a circuit, activating the warning modules.
