Can You Die From Running Your Car in the Garage?

If you leave your car running in the garage and it is closed, you will create a toxic environment that can kill you within minutes. The carbon monoxide released by your car’s exhaust will build up quickly, especially if you have a closed space such as a garage or shed.

Carbon monoxide has no color or odor, so you won’t be able to smell it until it’s too late and by then, it will be too late for you to do anything about it.

What are the dangers of doing this?

The dangers of this activity are numerous, and they’re all related to carbon monoxide poisoning. Carbon monoxide is a colorless and odorless gas that can’t be detected by the human nose or eye, so you won’t know it’s there until it’s too late.

Carbon monoxide poisoning causes difficulty breathing, dizziness, nausea, and vomiting. If you have symptoms of CO poisoning, get out of the garage immediately and call 911.

What else can happen if you do run your car in a garage?

You could easily kill yourself. If you don’t have the garage door open and the engine running, carbon monoxide can build up in there and kill you before you even realize what’s happening.

Also, it’s illegal to run a vehicle in a garage unless it has an exhaust system that vents carbon monoxide outside of the structure If there are any sparks or flames coming from the car’s engine or exhaust system, those will set fire to anything nearby including your house.

If you leave the car on for too long without circulating fresh air through it, then it will run out of gas. Even if there is enough gas in the tank for your car to run for an hour or two while it’s in the garage with no circulation at all after that time period is up then this will happen anyway because of how long it takes for exhaust fumes coming out of cars tailpipes to build up enough carbon monoxide levels inside them so that they stop working properly.

Why you shouldn’t run your car in a garage?

The dangers of running a car in a garage are many. Aside from the obvious risk of carbon monoxide poisoning and fire, there’s also the fact that you might never get your car out.

Garage doors are notoriously tricky to open and close. If you have an automatic garage door opener, it can be hard to tell if it’s actually going to work or not when you’re rushing around in a panic trying to get out of there.

It’s also difficult to tell if your garage door has been damaged by weather or other circumstances, which would prevent it from closing properly. If your garage is attached to your home, you run the risk of damaging your house by trapping carbon monoxide inside and creating an oxygen-free environment for too long.

Even if you don’t live next door to anyone else, having a gas leak in your house is dangerous enough and that’s just one more thing for firefighters (and possibly even the police) to worry about when they arrive on the scene.

Health risks of running your car in a garage

The most obvious risk is carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that can seep into your garage and cause serious injury if you run your vehicle in the garage while it’s closed.

Carbon monoxide can also cause headaches, dizziness, nausea, and vomiting. A low level of exposure can lead to long-term health problems such as chronic obstructive pulmonary disease or even death at high levels of exposure.

Other potential health risks include inhaling engine exhaust fumes which may contain toxic chemicals such as hydrocarbons and nitrogen oxides that can irritate your eyes, nose, and throat and cause asthma attacks in sensitive individuals.

How can you die from running your car in the garage?

You can’t die from running your car in the garage, but you can hurt yourself. If you leave the car running with no one in it, the car will fill with carbon monoxide. Carbon monoxide is a poisonous gas that is colorless, odorless, and tasteless.

It’s what people breathe in when they have CO poisoning. The symptoms of CO poisoning include headaches, dizziness, and weakness. If you notice any of these symptoms and suspect CO poisoning, get out of the area immediately and call 911 or your local emergency number.

If you’re going to be driving around in your car while it’s running, make sure there are no leaks or other problems with the exhaust system. You should also check your levels regularly to make sure your tank isn’t empty or close to empty this can cause problems too.


If you’re running your car in the garage, there are a lot of things that could go wrong. You could die from carbon monoxide poisoning, you could set the house on fire, and/or you could crash out of the garage into your neighbor’s house.
