RULES * USA - NHTSA sets new braking one
The National Highway Traffic Safety Administration today, July 24, issued a long-awaited regulation to tighten the stopping distance standards on heavy-duty tractors
Washington,DC,USA -eTrucker, by Avery Vise -24 July 2009: ... The new standard generally requires a tractor traveling at 60 miles per hour come to a complete stop within 250 feet when loaded to its gross vehicle weight rating. The old standard required a complete stop within 355 feet. For a small number of very heavy, severe service tractors, the stopping distance requirement will be 310 feet under these same conditions. And the final rule requires that all heavy truck tractors must stop within 235 feet when loaded to their “lightly loaded vehicle weight.”... Three-axle tractors with GVWRs of 59,600 pounds or less must meet the reduced stopping distance requirements by Aug. 1, 2011. Two-axle tractors and tractors with GVWRs above 59,600 pounds must meet requirements by Aug. 1, 2013... Manufacturers can use any of several options to meet the requirement, including installation of enhanced drum brakes, air disc brakes or hybrid disc/drum systems, NHTSA said...Labels: rules and regulations
