California CHP Finds Exhaust Leak Directly Below Sleeper Berth โ Warns Deadly Carbon Monoxide Could Enter Cab While Driver Rests, Truck Placed Out of Service
FAIRFIELD, CALIFORNIA โ California Highway Patrol inspectors at the Cordelia Commercial Vehicle Enforcement Facility placed a semi-truck out of service after discovering a leaking exhaust system located directly beneath the driver and sleeper compartment โ a violation that CHP warned could allow deadly fumes to enter the cab while a driver sleeps or rests.
The violation was found during a routine inspection at the Cordelia facility in Fairfield. CHP placed the truck out of service for the exhaust leak as well as additional violations found during the inspection.
"Exhaust leaks in this location can allow fumes to enter the vehicle, creating a hazardous environment for the occupant(s)," CHP said.
Exhaust leaks beneath the sleeper berth pose a particular danger because carbon monoxide โ a colorless, odorless gas โ can build up in the cab while a driver is resting with little warning. Symptoms of carbon monoxide poisoning include headache, drowsiness, nausea, confusion, shortness of breath, chest pain, dizziness, fainting, abdominal pain, visual changes, difficulty walking, and hallucinations.
If you experience any of these symptoms while in your truck, exit the vehicle immediately and seek medical care. CHP also recommends that drivers consider purchasing a battery-powered carbon monoxide detector for their cab as an added layer of protection.
