Abstract
The apparatus measures the braking of the vehicle and the turning action on the wheels, secondarily the speed and the acceleration or the running of the engine. It records these measurements graphically and simultaneously so that, if necessary, the driver may correct his mistakes. A warning is activated if the vehicle is braked and its wheels are turned at the same time. This warning is graphic, audible or visual. The apparatus is useful for driving instruction and tests.
