Massive driver turnover continues to plague the trucking industry.

The turnover rate at large carriers rose two percentage points to 102 percent in the fourth quarter of 2015, according to the American Trucking Associations’ quarterly Trucking Activity Report.

It spiked 21 points to 89 percent at smaller carriers, the trade group reported.

“This elevated turnover rate shows that the driver market remains a challenge for truckload fleets,” said Bob Costello, the ATA’s chief economist.

This is the second straight quarter that the driver turnover rate was at least 100 percent, the first time that has occurred since 2012.

The turnover rate at less-than-truckload carriers rose one point to 11 percent in the fourth quarter.
