Motorcoach safety has received increased public attention after several serious accidents during 2011, some of which involved curbside carriers. As a result, the National Transportation Safety Board conducted an investigation of motorcoach safety with an emphasis on curbside operations. The objectives of the investigation were to (1) describe the characteristics of the curbside business model among interstate motorcoach carriers; (2) describe the safety record of interstate motorcoach carriers, including those that use a curbside business model; and (3) evaluate the adequacy of safety...

This safety report represents the culmination of a year-long National Transportation Safety Board (NTSB) effort focused on the problem of substance-impaired driving. The report addresses the necessity of providing all the following elements to achieve meaningful reductions in alcohol-impaired driving crashes: stronger laws, improved enforcement strategies, innovative adjudication programs, and accelerated development of new in-vehicle alcohol detection technologies. Moreover, the report recognizes the need for states to identify specific and measurable goals for reducing impaired driving...

Since its inception, the National Transportation Safety Board has been concerned about the evacuation of commercial airplanes in the event of an emergency. Several accidents investigated by the Safety Board in the last decade that involved emergency evacuations prompted the Safety Board to conduct a study on the evacuation of commercial airplanes. The study described in this report is the first prospective study of emergency evacuation of commercial airplanes. For the study, the Safety Board investigated 46 evacuations that occurred between September 1997 and June 1999 that involved 2,651...

"Public aircraft" are aircraft operated for the purpose of fulfilling a government function that meet certain conditions specified under Title 49 United States Code, Section 40102 (a)(37).

The goal of this National Transportation Safety Board study was to better understand the risk factors associated with accidents that occur in weather conditions characterized by IMC or poor visibility.

In the pipeline industry, Supervisory Control and Data Acquisition (SCADA) systems are used to collect data from pipeline sensors in real time and display these data to humans who monitor the data from remote sites and remotely operate pipeline control equipment. This National Transportation Safety Board study was designed to examine how pipeline companies use SCADA systems to monitor and record operating data and to evaluate the role of SCADA systems in leak detection.

This study used manufacturer records, aircraft investigation information, and a tailored subset of general aviation activity survey data to assess how the transition to electronic primary flight display (PFD) avionics has affected the safety of light aircraft. The study also evaluated the resources and requirements supporting the transition to this new technology.

In 2003, airbags were first certificated for pilot and copilot seats on general aviation (GA) aircraft, and as of August 2010, they have been installed in nearly 18,000 seats in over 7,000 GA aircraft. In 2006, the National Transportation Safety Board (NTSB) initiated an exploratory case series study to consider airbag performance in GA accidents.

There are 8.22 million single-unit trucks registered in the United States, which travel more than 110.7 billion miles each year. Although single-unit trucks comprise three percent of registered motor vehicles and four percent of miles traveled, they are involved in nine percent of fatalities among passenger vehicle occupants in multivehicle crashes. Crashes involving single-unit trucks and passenger vehicles pose a hazard to passenger vehicle occupants due to the differences in weight, bumper height, and vehicle stiffness.
