Stopping Distance For 18-Wheelers
The National Highway Transportation Safety Administration (NHTSA) offers a wealth of research on all things transportation related. One study provides the following information on the topic of braking distances for trucks of various weights. While this blog will only provide brief highlights - you may visit www.nhtsa.gov for further information.
Current Stopping Distance Requirements for Medium and Heavy Duty Vehicles
Vehicle Type:
Tractor- trailer-Stopping Distance from 60 mph was a whopping 335 feet.
These numbers are not new and have been consistent for may years. However, with the advances in technology we should expect better braking from commercial vehicles.
The purpose of the research was to validate current stopping capabilities for vehicles and using these figures as a starting point for improving expectations. The following suggestions are currently under consideration:
*Substantially shorten the required stopping distances for ALL vehicles - buses, automobiles, semi-trucks and tractor trailers from their current abilities.
*Improve heavy duty brake systems for semi-trucks and tractor trailers AND increase brake retardation force.
The research study was presented recently by two NHTSA project engineers.
