Final answer:
Florida law mandates that if a vehicle's rear window is non-transparent, the vehicle must have side mirrors on both sides to ensure visibility.
Step-by-step explanation:
In Florida, if the rear window of your vehicle is made of, covered by, or treated with any material that makes the window non-transparent, the law requires your vehicle to have side mirrors on both sides. This is to ensure that the driver has adequate visibility of the area behind the vehicle, which would otherwise be obscured. Having non-transparent materials on the rear window without alternative means of ensuring visibility can pose a safety risk. While backup cameras and warning beepers are useful safety features, Florida law specifically mandates the presence of side mirrors to comply with visibility requirements.
