One feature of the VAC is to prevent unauthorized access to the VAC, and, optionally, the vehicle. Each
VAC is assigned a vehicle number (often similar to the number marked on the side of the vehicle), and
that number has an associated authorization list that contains valid drivers and, for each driver, the times
