Abstract
In a highway tractor trailer vehicle, a brake control sensor is operative to detect each activation of the manual trailer brake control, and a recorder receives and stores data comprising a speed of the tractor at each manual trailer brake control activation. Trailer brake wear is reduced by penalizing an operator of the tractor for each unauthorized activation of the manual trailer brake control. Testing of the connection of the tractor to the trailer is encouraged by tracking the activation of the manual trailer brake control and penalizing the operator for failure to test the connection.
