Having a street vehicle in Florida means you must follow the laws and regulations set by the state when making changes. If you live in Florida or are moving to Florida, the following information will help you understand how you are allowed to customize your vehicle.
Sounds and noise
Florida requires all vehicles to adhere to certain sound level limits from both sound systems and mufflers. This includes:
The noise level of vehicles manufactured between January 1, 1973 and January 1, 1975 must not exceed 86 decibels.
The noise level of cars manufactured after January 1, 1975 cannot exceed 83 decibels.
Functions: Also check your local Florida County laws to make sure you comply with any municipal noise ordinances that may be stricter than state laws.
Frame and suspension
Florida does not limit the frame height or suspension lift limit for vehicles provided that the bumper height does not exceed the following bumper height specifications based on gross vehicle weight ratings (GVWRs):
Vehicles up to 2,000 GVRW – Max front bumper height 24 inches, max rear bumper height 26 inches.
Vehicles 2,000– 2,999 GVW – Max front bumper height 27 inches, max rear bumper height 29 inches.
Vehicles 3,000-5,000 GVRW – Max front bumper height 28 inches, max rear bumper height 30 inches.
ENGINES
Florida does not specify any engine modification regulations.
Lighting and windows
Lanterns

Window tinting
Non-reflective windshield tinting is allowed above the AS-1 line provided by the vehicle manufacturer.

Rear and rear side windows must let in more than 15% of the light.
Reflective shades on the front and rear side windows cannot have a reflectivity of more than 25%.

A decal is required on the driver's door jamb stating the permitted tint levels (provided by DMV).
Vintage/classic car modifications
Florida requires cars older than 30 years old or made after 1945 to have antique plates. To obtain these license plates, you must apply for a Street Rod, Custom Vehicle, Horseless Carriage, or Antique registration with the DMV.
