Less-than-truckload (LTL) carrier YRC Worldwide Inc. today announced it will impose a 6.9-percent general rate increase on North American non-contract shipments, becoming the fourth LTL carrier in less than three weeks to impose the same rate hike on non-contractual customers.

UPS Freight, the LTL unit of UPS Inc., fired the first salvo on July 1 when it announced a 6.9-percent hike. It was followed by ABF Freight System Inc. and late yesterday by Con-way Freight, the LTL unit of Con-way Inc.

The YRC rate changes take effect Aug. 1 and will also apply to minimum shipment charges and so-called accessorials, value-added services that supplement the actual linehaul service. Rates for shipments moving within Canada will remain unchanged for now, YRC said.

The YRC adjustments come three days before the financially ailing company is set to unveil a sweeping restructuring plan that many believe will set its fate for years to come. On July 22, it is expected to name a new CEO to replace long-time head William D. Zollars, who said he would retire once the restructuring is completed and a successor is named.
