The mornings are getting colder, and Renoites heading to work or school may be tempted to start their vehicles early so they can warm up before getting in.

But state law and local police urge caution.

Leaving a car running while unattended is illegal in many places across the country, including Nevada.

Here’s a look at what Nevada law says about leaving a car unattended with the engine running and what risks Reno residents run leaving their car idling while they’re not in it.

Can I leave my car running while I’m not in it?

No. Nevada law prohibits leaving a vehicle unattended while the engine is running.

State law says: “The person driving or in charge of any motor vehicle, except a commercial vehicle loading or unloading goods shall not permit it to stand unattended without first stopping the engine, locking the ignition and removing the key.”

The statute does not apply to vehicles that use remote starters, as long as the key is not in the ignition and the car remains locked.

What are the risks of leaving a car running unattended?

According to local law enforcement, leaving a car running while unattended can lead to an increased risk of your car getting stolen.

“It’s a very bad idea,” Reno Police Chief Kathryn Nance said. “Your car will get stolen [if idling without you in it.] It’s just a matter of time.”

Does it cause harm to warm up your car?

Not only does leaving your car with the engine on unattended increase the risk of your car getting stolen, idling your engine could damage your engine’s pistons, decrease your car’s fuel efficiency and hurt the environment, according to Firestone.
