Question Analysis
The Texas DPS Driver Handbook states that carbon monoxide (CO) is a colorless, odorless, and deadly gas produced by internal combustion engines. To prevent CO poisoning, drivers should regularly inspect the exhaust system for leaks, never leave an engine running in an enclosed space such as a garage, and avoid driving with vents open when following another vehicle closely, as this can draw in exhaust fumes. The handbook emphasizes these preventive measures as essential for safety.
Correct Answer Analysis
Correct Answer: All of the above.
The correct answer is 'All of the above' because each of the three listed actions is a recommended practice to avoid carbon monoxide poisoning: regular exhaust system checks prevent leaks, turning off the engine in a garage prevents CO buildup in enclosed spaces, and closing vents when following closely reduces the intake of exhaust fumes from other vehicles.
Wrong Options Analysis
Option: Have their exhaust system checked regularly to be sure it does not leak.
This statement is actually correct and is one of the recommended measures. It is not an incorrect option; it is part of the correct answer 'All of the above'.
Option: Keep their car turned off when it is enclosed in a garage.
This statement is also correct and is a key prevention method. It is not an incorrect option; it is included in 'All of the above'.
Option: Close vents when following closely behind another car.
This statement is correct as well, as it helps prevent exhaust fumes from entering the vehicle. It is not an incorrect option; it is part of 'All of the above'.
