Your plate lamp only has to work if a plate is required on the back of your truck. For example, in Texas, you only need one plate on the front, meaning no rear plate lamp is required. But if your truck does need a rear plate, you must have it illuminated. If you have two lamps installed but only one works, that’s still compliant, so you can’t be written up for the second one being out. #trucking #cdl #truckdriver #FleetManagement | Safety Compliance & Training LLC
