ABSTRACT:
A speed awareness device for allowing passing traffic to perceive from a source other than their own speedometers their true speed. A trailer supports a container within which a radar source is contained operatively connected to a display panel. A suitable source of power operates the radar and display and includes a battery, an optional photo voltaic source to power the battery and a plurality of instrumentalities to preclude or render less likely that the trailer will be moved by unauthorized personnel. These instrumentalities include a removeable trailer hitch, an axle lock, support stands for elevating the trailer and an internal alarm system.
