Can I Sit in My Car with the Engine Running?

Yes, But It’s Not Recommended

In general, it is not recommended to sit in your car with the engine running for extended periods of time. There are a few reasons for this:

Carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that is produced by burning gasoline. When the engine is running, carbon monoxide is released into the exhaust system. If the exhaust system is not working properly, carbon monoxide can leak into the passenger compartment of the car. Carbon monoxide can cause headaches, dizziness, nausea, and even death.
Fuel consumption. When the engine is running, it is using fuel. If you are just sitting in your car, you are not using the fuel to move the car, so it is being wasted.
Environmental pollution. When the engine is running, it is emitting pollutants into the air. These pollutants can contribute to smog and other environmental problems.

When It’s OK to Sit in Your Car with the Engine Running

When you are warming up your car in cold weather. In cold weather, it is necessary to warm up your car before driving. However, you should only run the engine for a few minutes until the inside of the car is warm.
