What is it?

This index provides a measure of the number active (plated) tractors, relative to the number of active drivers, for reporting carriers. The count of drivers included in this index capture both part-time and full-time employees, and independent contractors. For part-time, the counts are reported on a FEL basis (Full Time Equivalent). The carriers reporting the data for this index are participants in Truckload Carriers Association’s TPP program.

Formula: (Truck Count) / (Driver Count)

Who is interested?

Anyone that has an interest in freight movement patterns. i.e. Shippers, freight brokers, fleet managers, executives in a transportation company, owner operators.

What does it tell me?

Ideally, carriers have a calculated index value of 1:1 or higher. Anything less indicates unseated tractors, which, as a by-product, indicates lower asset utilization.
