Question: 1 / 400

Why should a leaky exhaust system be repaired?

It wastes gas and oil

It causes the engine to run hot

It may allow dangerous fumes to enter the car

A leaky exhaust system should be repaired primarily because it can allow dangerous fumes, such as carbon monoxide, to enter the vehicle's cabin. Carbon monoxide is a colorless, odorless gas that can have serious health implications, including headaches, dizziness, and even life-threatening conditions in high concentrations. The exhaust system is designed to safely channel harmful gases away from the engine and out of the vehicle; any leaks compromise this function, exposing occupants to these toxic substances.

While other issues such as wasting fuel, causing the engine to overheat, or making the engine difficult to start may be related to exhaust system problems, they do not pose the same immediate health risks associated with inhaling toxic gases. Thus, the top priority in addressing a leaky exhaust system is to ensure passenger safety by preventing the entry of harmful fumes into the car.
