Given how massive they are, trucks need to be well-lighted when moving on Pennsylvania's highways and byways. The Keystone State has a number of rules governing the illumination trucks need to have when on the roads. If a truck lacks the proper lighting, the truck driver, truck owner and truck company can get into trouble. It may be useful to have a brief overview of the lighting requirements for trucks in Pennsylvania.
First, trucks are required to have either two white, seven-inch type 2 headlamp units or two white, 5.75-inch type I headlamp units with two white, 5.75-inch type 2 headlamp units. They also need two red taillamps and two red stoplamps. Trucks additionally need one white license plate lamp and four red and two amber reflex reflectors. They also need two red or amber turn signal lamps and two amber turn signal lamps.
Trucks must have three amber and three red identification lamps. They need two amber and two red clearance lamps. They need two amber intermediate side marker lamps and two amber intermediate side reflectors. Additionally, Pennsylvania law provides for the required location for each of these lights and reflectors.
What can happen if a truck does not have the required lights in their required locations? Truck drivers, owners and others may be subject to penalties for improper lighting. Also, if a truck's improper lighting can be proved to have caused an accident, compensation may be available to victims for their lost wages, pain and suffering, and other legally recognized damages.
