ABSTRACT:
A tamper proof, economically constructed, easily installed, drive recorder or instrument for making a permanent record of the manner in which a vehicle is driven is provided, and comprises an instrument which may be located in and secured to the vehicle of a driver whose driving habits are to be recorded. The recorder preferably has two compartments each having inclined bottom surfaces to normally position a heavy ball by gravity. The inclined bottom surfaces are provided with recording paper, and the vehicle's acceleration, braking or cornering causes the heavy balls to move from their normal positions up the inclined surfaces and the heavy balls to leave a track on the recording paper to make a permanent recording of the drive.
