This law permits older passenger carrier vehicles made before 1968 to use green identification lights. Buses can have illuminated signs to show destinations or identification as long as these signs do not produce glaring light. Such signs can be placed inside the bus if they follow specific regulations. For other commercial vehicles, an illuminated identification sign is allowed on the front, but it must be a specific size and emit a soft white light without glare.

This law addresses the rules for identification lamps on certain vehicles, specifically commercial vehicles and other vehicles that are 80 inches or wider. Vehicles made before January 1, 1968, can have identification lamps that show amber, green, or white lights at the front and red lights at the rear.

For vehicles made on or after January 1, 1968, the front identification lamps can only show amber lights, while the rear lamps must still be red. This distinction is based on the vehicle's manufacturing date.

This law allows buses run by publicly owned transit systems to use a device that can change traffic light patterns. It lays out specific conditions: if the device is a flashing light, it shouldn't be too bright. The bus systems must get permission from transportation or local authorities to use the device on certain routes. Finally, they must give priority to emergency vehicles when changing traffic signals.

This law allows buses operated by publicly owned transit systems to have illuminated signs for displaying destinations, route numbers, and public service announcements. The signs should emit soft, non-glaring light, and cannot use red lights on forward-facing signs. They must be no larger than 720 square inches and shouldn't interfere with any safety equipment on the bus. Signs can show messages related to public transit services and must comply with certain display timings if they show dynamic messages. The law also ensures compliance with federal regulations, like the Americans with Disabilities Act.
