keep your windows rolled up at all times.

Explanation:

Analyze carbon monoxide risks

Carbon monoxide (CO) is a toxic, odorless, and colorless gas produced by internal combustion engines. When a vehicle runs in an enclosed space, CO builds up rapidly to lethal levels.

Evaluate the options

• Never leave your vehicle running in an enclosed space, like a garage. This directly prevents the dangerous accumulation of toxic exhaust fumes.
• Allow your vehicle to idle for at least 10 minutes to warm up before driving on cold days. Idling, especially in semi-enclosed areas, increases CO accumulation and is unnecessary for modern vehicles.
• Replace your cabin air filter frequently. While part of Vehicle Maintenance, standard cabin air filters do not filter out carbon monoxide gas.
• Keep your windows rolled up at all times. This does not prevent CO poisoning and can trap gases if there is an exhaust leak.

Identify the correct safety practice

The primary and most effective safety rule to prevent carbon monoxide poisoning is to ensure the vehicle is never left running in enclosed spaces.

Answer:

• Never leave your vehicle running in an enclosed space, like a garage. (Correct answer)
• Allow your vehicle to idle for at least 10 minutes to warm up before driving on cold days.
• Replace your cabin air filter frequently.
• Keep your windows rolled up at all times.
