Which of the following is allowed regarding vehicle modifications?

Regarding vehicle modifications, choosing "None of the above" signifies that none of the provided options meet legal safety and regulation standards in Florida.

For vehicle modifications, it is important to comply with state laws to ensure safety and minimize noise pollution. Changing the exhaust system to make it louder is generally prohibited, as excessively loud exhaust systems can violate noise ordinances and can also be a nuisance to the public.

Adding stickers to the windshield can also be problematic, especially if they obstruct the driver's view or fall within the guidelines that restrict certain types of visual obstructions. Moreover, there could be restrictions on window tinting or other decals that interfere with safety clearances required by law.

Installing additional lights, particularly those that are not standard or approved, can create safety hazards for both the driver and other road users. Certain lights may not meet regulatory standards concerning color and brightness, leading to confusion on the road, particularly with other drivers and law enforcement.

It's crucial for vehicle owners to ensure any modifications comply with state regulations regarding safety, visibility, and noise pollution to avoid penalties and ensure road safety.
