During winter weather, which item should have extra attention during inspection?

• A. Exhaust
• B. Tires
• C. Battery
• D. Wipers

Answer: (A)

In winter, the exhaust system deserves extra attention because even a small leak can let deadly carbon monoxide enter the cab, especially when you’re warming the vehicle with the heater or defroster in enclosed spaces. Cold weather and road salt accelerate corrosion, so pipes, mufflers, clamps, and hangers can rust or crack more quickly, increasing the chance of a leak. During inspection, look for signs of rust, holes, cracks, loose or broken clamps, damaged or missing hangers, and any exhaust parts that appear to be sagging or dragging. Ensure the tailpipe is clear and that there’s no leakage when the engine is running. Tires, battery, and wipers are important in winter too, but exhaust leaks pose a unique safety risk in cold weather due to potential CO buildup inside the vehicle.
