Design and Operation of Work Zone Strategies to Improve Large Truck Safety

Work zones can create special challenges for drivers of large vehicles, such as commercial motor vehicles, due to space restrictions. Road work must take place within highway rights-­of­-way and, often, within reduced numbers of lanes. Understanding how work zones can be designed to maintain the efficient movement of large freight transportation vehicles within the restricted right-­of­-way space and to ensure that Department of Transportation (DOT) and public works staff and highway contractors’ employees can safely work within work zones can provide significant benefits for all work zone users. The U.S. Department of Transportation, Federal Highway Administration (FHWA), the Federal Motor Carrier Safety Administration (FMCSA), the National Highway Traffic Safety Administration (NHTSA), the American Trucking Association (ATA), State Departments of Transportation, local and State law enforcement agencies, academic researchers at the Texas A&M Transportation Institute, and others have worked to develop approaches to reduce the numbers of work zone crashes involving large trucks. This document on design and operation of work zones is a product of this ongoing effort. In this document, large trucks include vehicles commonly referred to as commercial motor vehicles, semi­-tractor trailers, 18-­wheelers, or semis as well as single-unit trucks larger than 10,000 lbs gross vehicle weight. This document is organized in the following sections: (1) How Significant Is the Large Truck Safety Issue in Work Zones? (2) Why Are Large Trucks Overrepresented in Work Zone Crashes? (3) Ways to Improve Large Truck Safety in Work Zones: Work zone design practices to better accommodate large trucks; Ways to help truck drivers better negotiate work zones.
