You are driving with the windows closed. You begin to feel dizzy and sleepy, and you have a headache and ringing in your ears. What is the most likely danger, and what should you do?
Correct answer: Carbon monoxide; pull off safely, stop the engine, and open the windows.
Why
Carbon monoxide is a colorless, odorless, poisonous gas from engine exhaust. If you feel weary, dizzy, sick to your stomach, or have a headache or ringing in your ears, stop the engine and get fresh air. Prevent it by having the exhaust system checked for leaks, by not sitting for long periods in a parked car with the engine running, and by never running the engine in a closed garage.
