New Stopping Distance Mandate in Effect
New Stopping Distance Mandate in Effect
As of August 1, 2013, the federal mandate for vehicle stopping distance has changed.
All Two-Axle trucks must now stop in less than 250 feet at 60 mph. Three-Axle and Four-Axle trucks must stop in less than 250 to 310 feet at 60 mph. (depending on GVWR).
With this mandate, the use of a friction material that meets these requirements will have to be implemented on all vehicles covered by the mandate. Note that some manufacturers of brake shoes will be clearly labeling high performance shoes to indicate that the shoes meet federal Reduced Stopping Distance standards.
