    Given a binary status representation of delivery vehicles where 1 indicates an active vehicle and 0 indicates an inactive vehicle, develop a function that activates the next available vehicle by setting the leftmost inactive (0) bit to active (1). The solution will help optimize fleet capacity during peak traffic hours by systematically deploying standby vehicles when needed.
