Whether you currently live in Iowa or you are planning on moving to the state, you need to know the laws and regulations regarding vehicle modifications to ensure that your car or truck remains street legal throughout the state. The following are the vehicle modification laws applicable in Iowa.

Sounds and noise

Iowa has laws concerning both the sound systems and mufflers on vehicles. Additionally, they also require that horns can be heard from 200 feet, but are not harsh, unreasonably loud or produce a whistling sound.

Sound system

Iowa does not have any specific laws governing sound systems in vehicles, other than that they can’t produce noise levels that may harm, annoy or cause damage to any other reasonable person.

Mufflers

  • Mufflers are required on all vehicles and must be in proper working condition.

  • Bypasses, cutouts and other similar devices that amplify the sound are not permitted on mufflers.

  • Mufflers must prevent excessive or unusual smoke or noise when in constant operation.

Tip: Also check with local county laws in Iowa to make sure you are following any municipal noise ordinances that may be more stringent than state-level laws.

Frame and suspension

Iowa has the following regulations in place for the vehicle frame and suspension systems:

  • Vehicles can’t exceed 12 feet 6 inches in height.
  • There are no frame height or suspension lift limits.
  • There are no bumper height restrictions.

Engine

Indiana does not have regulations regarding engine swaps or modifications affecting performance. Porter and Lake Counties require emissions testing on vehicles with a Gross Vehicle Weight Rating (GVWR) of 9,000 pounds or less and that were manufactured after 1976.

Lighting and windows

Lights

  • Blue lights are not permitted on passenger vehicles unless driven by emergency personnel. In these cases, a certificate of authorization must be carried in the vehicle at all times.

  • Flashing white lights are not permitted on passenger vehicles unless the vehicle is owned by emergency personnel and authorization is granted.

  • Blue stationary and flashing lights are not permitted on passenger vehicles.

  • One spotlight is permitted.

  • Three auxiliary driving lights are permitted if mounted no lower than 12 inches and no higher than 42 inches.

Window tinting

  • Non-reflective tint can be applied to the top of the windshield above the AS-1 line from the manufacturer.

  • Front side windows must allow over 70% of light through.

  • Back side and rear windows can have any darkness of tint with both side mirrors on the vehicle.

  • Iowa law is not specific on reflect window tint, requiring only that it is not excessively reflective. Iowa does not allow medical exemptions for darker tint on front windows.

Antique/classic car modifications

Iowa allows vehicles that are 25 or more years old to be registered as antique. If the vehicle is registered as such, it can only be used for exhibitions, education or entertainment purposes. It can only be driven on roadways to or from these types of events or when requiring maintenance.

Chevrolet Equinox - Brake Pads Replacement (Rear) - Niles, Illinois
Rigo was great! He got there early, finished the job early, left everything clean. He changed my rear pads and rotors. The original quoted time was 90 minutes, he was done in about 60. He knows what he is doing and I am recommending him to all my friends and coworkers.

Rigo is a maverick hands down. Don’t take your car for work elsewhere. Especially great at Mercedes—this guy knows his profession! I will be using him for everything related to my car going forward.
