Abstract: FMCSA is seeking Office of Management and Budget (OMB) approval of a new information collection entitled “Study of Warning Devices for Stopped Commercial Motor Vehicles.” Participation in the study is voluntary, so in the event of participation, no small business will have an imposed burden that it is not willing to bear. Information collection activities are planned for an 18-month period. Parked or disabled commercial motor vehicles (PDCMVs) on the road negatively impact traffic operations and safety. FMCSA requires specific warning devices to be carried on all commercial motor vehicles (CMVs) and, except in the case of necessary traffic stops, be deployed near the vehicle whenever it is stopped on the road or shoulder. Advances in automated driving system (ADS) technology have raised critical questions regarding potential barriers to regulatory compliance with warning device safety standards and regulations which reference a “driver.” Alternative types of warning devices developed by industry, including those intended to increase driver safety during device deployment, have resulted in multiple applications for exemption from the corresponding safety regulations. These recent issues related to warning device requirements also call attention to unresolved questions of how and to what extent the use of such devices improves traffic safety. Given the increasing focus on ADS, questions surrounding the safety of CMV drivers when deploying warning devices, and the availability of new technology and alternative devices, there is a need to thoroughly evaluate the use of warning devices under current regulations. FMCSA has established a contract with Virginia Tech Transportation Institute (VTTI) to collect the information associated with this ICR. Under indirect oversight of an FMCSA Contracting Officer’s Representative, experienced VTTI research staff will perform all data collection activities described in this ICR. The findings will contribute to safety by ensuring that FMCSA’s decisions and regulations are data-driven and based on safety. FMCSA’s purpose for collecting this information is to develop an understanding of whether and to what extent the deployment of warning devices near a stopped commercial motor vehicle affects the driving behavior of passing motorists, and those elements of driving behavior which have the potential to influence the likelihood of a crash involving the stopped vehicle.
