Before a winter trip, why inspect the exhaust system and cab seals with extra care?
- A.Exhaust leaks only matter in summer heat
- B.Cab seals have no safety role
- C.Idling removes all exhaust risk
- D.Drivers idle more and close the cab tightly in winter, so an exhaust leak can build up deadly carbon monoxide inside
Correct answer
D. Drivers idle more and close the cab tightly in winter, so an exhaust leak can build up deadly carbon monoxide inside
Why
Cold-weather operation means more idling, closed windows, and snow that can block exhaust outlets, all of which raise carbon monoxide exposure. A sound exhaust system and a clear tailpipe area are life-safety items in winter, not comfort items.
