Abstract: A truck safety recorder is utilized by the driver of a truck for recording the amounts of time that the driver has spent actually driving, the amount of time that the driver has been on duty, and the amount of off duty time that the driver has had for sleeping in accordance with Federal Motor Carrier Safety Regulations. The recorded information is displayed for inspection by highway officials. The truck safety recorder is removably secured to a holder mounted to the vehicle and may be carried on the person of the driver when the truck is not being driven. A clock subsystem within the truck safety recorder generates a periodic timing signal and includes a chronograph, stopwatch, and an alarm for the convenience of the user. A microprocessor subsystem responds to the periodic timing signal by incrementing amounts of time recorded by the truck safety recorder.
