Trucker school bustles amid US driver shortage Business is booming at the California Truck Driving Academy amid a nationwide shortage of long-haul drivers that has led to promises of high pay and instant job offers.

Lack of drivers at the ports has helped fuel the surge at the nearby California Truck Driving Academy, where instructors in reflective vests keep watch as students steer semis around a fenced-in paved lot.
