What is it?
The Line4 index is a measure of the spread between the average amount of driving (HOS11) and non-driving (HOS14) by subtracting line 3 from line 4 of a driver’s electronic log. The index is expressed in hours such that a reading of 7.70 hours would translate to 7 hours and 42 minutes of total work time (driving and non-driving).

What does it tell me?
A commercial vehicle driver operating outside the 100 air-mile radius from base and therefore required to have a ELD device installed, and who operates under either the 60 hours / 7-day or 70 hours / 8-day rule, cannot drive more than 11-hours without taking a 10-hour consecutive rest break. The HoS11 index is a measure of driver utilization levels within the 11-hour maximum and highlights areas of inefficiency and areas for improvement in load scheduling and the setting of appointment times.
