However, there are a few exceptions to this rule. For example, classic cars that are at least 25 years old are exempt from smog inspections and emissions regulations. Additionally, vehicles that are registered in a county that does not have a smog inspection program may also be exempt.
If you are unsure whether or not it is legal to remove smog equipment from your car in Nevada, you should contact the Nevada Department of Motor Vehicles (DMV) for more information.
