During winter weather inspections, which system should receive extra attention?

• A. Exhaust
• B. Brakes
• C. Suspension
• D. Lights

Answer: (A)

The main idea is that the exhaust system deserves extra attention because a hidden exhaust leak can lead to dangerous carbon monoxide entering the vehicle, especially when you’re using the heater or defroster in cold weather. Winter conditions, including moisture and road salt, promote rust and corrosion, which can create holes or weak spots in pipes, the muffler, or hangers. A leak might not be obvious at first, but it can let exhaust gases into the cab, posing a serious health risk even if you don’t notice the smell or sound. So, inspect the exhaust path from the engine back to the tailpipe for rust, holes, cracks, loose or missing mounts, damaged hangers, or loose connections. Ensure heat shields are secure and that the tailpipe has proper clearance and isn’t touching the ground or other components. Prioritizing this check in winter helps prevent a dangerous CO buildup when you’re heating and cooling the interior.
