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
