Why must you avoid running a vehicle engine in a closed garage?
Correct answer: Exhaust fills it with deadly, odorless carbon monoxide.
Why
Carbon monoxide is an odorless, colorless gas in vehicle exhaust. Do not idle an engine in a garage. Weariness, dizziness, nausea and yawning can be warning signs. If symptoms suggest exposure, get to fresh air and call 911 for medical help. Stay away from the contaminated area and do not drive yourself for treatment.
