California is the “incubator” for commercial vehicle innovation that will spread throughout the nation, generating a wave of new powertrains and driver-assistance technologies designed to decrease truck emissions and increase safety and freight efficiency, a vehicle engineering consultant said.

A notice from the U.S. Environmental Protection Agency to revisit parts of the Phase 2 final rule on greenhouse gas emissions from heavy- and medium-duty trucks isn’t likely to create changes quickly, as the agency has not presented plans for expedited action and environmental groups are vowing to pursue a challenge in a federal appeals court — once the case is no longer being held in abeyance.

Legislation that would authorize the use of twin 33-foot trailers nationwide would decrease safety and damage freight infrastructure, the Mississippi Transportation Commission recently told a federal policymaker.

TT's Seth Clevenger and Eric Miller discuss the impact of the Aug. 28 announcement that CVSA will employ a "phased-in" enforcement of the electronic logging device mandate that takes effect Dec. 18, 2017.

A federal committee created to work on autonomous transportation hasn’t moved an inch under President Donald Trump.

Commercial vehicle inspectors will issue citations to motor carriers operating vehicles without electronic logging devices beginning Dec. 18 but will not place vehicles out of service until April 1.

Oak Ridge National Laboratory’s new director said Aug. 23 the lab is considering testing in Chattanooga related to autonomous driving and long-haul trucking.

Less than five months from the starting date of Phase 2 of the federal rule on GHG emissions from trucks, a statement from EPA Administrator Scott Pruitt on his plan to revisit the regulation’s sections on trailers and glider kits has created confusion and uncertainty.

When the U.S. government finally got around to regulating auto safety in 1967, it insisted that every car have seatbelts and that the steering column be engineered to absorb impact so it wouldn’t spear the driver.
