What is true about operating a vehicle in cold weather?
Correct answer: Your windshield washer fluid should contain antifreeze.
Answer options
- AYour windshield washer fluid should contain antifreeze Correct
- BAn engine cannot overheat when temperatures are very low
- CLeaks in the exhaust system pose less risk when it is cold outside
Why
Ordinary water or summer washer fluid can freeze on the glass and block your view, so winter fluid with antifreeze is needed. An engine can still overheat in the cold, for example if the radiator shutters freeze shut or the winterfront is closed too far, and exhaust leaks are more dangerous in winter because the cab is usually closed up.
