What’s in it

ISSUANCE AND DISPLAY OF ONE REGISTRATION PLATE. Under current law, two registration plates are issued for a motor vehicle other than an autocycle, motorcycle, motorized bicycle, or truck tractor, and are required to be attached to the front and rear of the vehicle. This bill provides that only one registration plate must be issued for a motor vehicle. The registration plate must be attached to the rear of the motor vehicle, except that the registration plate for a truck tractor must be attached to the front of the truck tractor, in accordance with current law.

Read the full explanation

The bill also makes corresponding changes, directs the Code editor to make necessary changes, and provides for the transition from the use of two registration plates to the use of one registration plate. A person who was issued two registration plates is authorized to attach only one plate, in accordance with the bill, on and after the effective date of the bill, and must transfer or return both plates if a transfer or return is required. WINDOW TINT. Under current law, a person is prohibited from operating a motor vehicle equipped with a front windshield, a side window to the immediate right or left of the driver, or a sidewing forward of and to the left or right of the driver (window) which is excessively dark or reflective so that it is difficult for a person outside the motor vehicle to see into the motor vehicle through the window.5), “excessively dark or reflective” means the window does not meet a minimum standard of transparency of percent light transmittance. However, the requirement does not apply to a person who operates a motor vehicle owned or leased by a federal, state, or local law enforcement agency if the operation is part of the person’s official duties. The bill strikes the authority of the DOT to adopt rules establishing a minimum measurable standard of transparency and instead prohibits a person from operating on the highway a motor vehicle equipped with a window that meets a minimum standard of transparency of less than percent light transmittance.438 is punishable by a scheduled fine of $70.
