A commercial motor vehicle with an exhaust leak beneath the cab may continue operating in service as long as the driver keeps the cab windows open for ventilation.
Cevap: Cevap
Cevap
False
The statement is false because commercial driver safety regulations strictly forbid operating a vehicle with exhaust leaks that can enter the cab or sleeper berth. Carbon monoxide is a lethal, odorless gas that can overcome a driver before it is noticed, and opening windows does not reliably prevent fumes from entering.
Adım Adım Çözüm
Anahtar Kavram
Exhaust leaks beneath or near the cab present an immediate carbon monoxide poisoning hazard and render the vehicle unsafe to operate regardless of window ventilation.
