Manufacturer ArvinMeritor Inc. said it lost $162 million in the April-to-June quarter, while also announcing last week it has found a buyer for its light-vehicle wheels business and has stepped up its marketing effort for truck disc and drum brakes ahead of the government’s new truck stopping-distance rule.

WASHINGTON — Transportation Secretary Ray LaHood an-nounced last week he will take steps to try to further curb distracting driving activities such as text messaging or using a cell phone or a Global Positioning System device.

There were no surprises in the new federal rule designed to improve the braking power of a standard, fully loaded, tractor-trailer by almost one-third.

The National Highway Traffic Safety Administration’s decision to cut the maximum allowed stopping distance for large trucks by 30% will increase truck buyers’ costs somewhat, but will not force a widespread shift to new technology such as air disc brakes, industry groups and manufacturers said.

In reference to the story, “Safeway Fleet Set to Fill Tires With Nitrogen,” which appeared July 6 on p. 8, I have been using nitrogen in my fleet since 2005. We have noticed that the tires stay at a constant pressure, and we have been able to get well over 250,000 miles out of our drive tires and 150,000 miles out of our steer tires.

Grocery retailer Safeway Inc. said it will begin inflating its truck and trailer fleet tires with nitrogen instead of compressed air.

Ryder System said it has been certified as a third-party logistics provider in the Custom-Trade Partnership Against Terrorism program, an initiative that seeks to promote supply chain security and reduce border vulnerabilities.

Heavy-duty U.S. truck sales continued their severe slide into a fifth month, as retail volume fell 39% in May, while the year-to-date total now lags the pace of last year by 33.9%, according to WardsAuto.com.

Diesel emission standards change again in January 2010, but unlike the previous modifications when all manufacturers used essentially the same emission-controlling technology, medium-duty truck buyers next year will have a choice of competing systems.
