Abstract: An externally-mounted camera system for large commercial trucks. The video cameras are positioned around the outside of the vehicle and feed their video images to a control unit within a tamper-proof black box typically located within the truck's cab. The cameras are wide-angle 360 degree type cameras and only four cameras completely surrounding the truck. This system is designed to work with the Federal Motor Carrier Safety Administration and Accident Reporting regulations, standards, and protocols. The video feeds will be attached to accident reports and reviewed by the federal authorities who provide feedback in compiled statistics and enhanced safety regulations.

Abstract: Illuminated message displays improve improving traffic safety by notifying drivers of the turning characteristics of semi trailers. Lamps mounted on the front of a circuit board and controlled by a microprocessor display a pattern of messages to warn motorists of the need to not be adjacent to a semi trailer when it makes a right hand turn, to notify motorists when a right hand turn is imminent, and to thank motorists for their cooperation. A wire connects the microprocessor and circuit board to the taillights of a semi trailer so that they are powered when the taillights are turned on. Circuit board holders releasably attach the circuit board to the rear door of a semi trailer. A pair of brackets with end caps are attached to the bottom of the rear bumper of a semi trailer to hold the circuit board and plates safely out of the way when the rear door of the semi trailer is opened.
