This study analyzes the incidence rates of incapacitating injuries as well as the commonly injured body regions among children under 8 years old involved in motor vehicle traffic crashes.

This document describes the method of sampling and the method of estimation which are used in the Crashworthiness Data System

This report examines the database structure and the usefulness of each of the crash data collection systems closely. The report describes how each data system functions and serves a different and unique purpose.

This report presents a statistical analysis of crash data in order to determine the effectiveness of antilock brakes in tractor-trailer combination vehicles. Federal Motor Vehicle Safety Standard No. 121, Air Brake Systems, mandates antilock braking systems on virtually all new air-braked vehicles with a GVWR of 10,000 pounds or greater. ABS is required on tractors manufactured on or after March 1, 1997, and air-braked semitrailers and single-unit trucks manufactured on or after March 1, 1998..

The purpose of this reference guide is to introduce the historical coding rules of the Fatality Analysis Reporting System (FARS) from 1975 to 2009. In other words, this guide presents the evolution of FARS coding regulations up to the year 2009.

This multi-year analytical user's manual provides documentation on variables that are contained in the GES and other useful information that will enable the users to become familiar the data system.

This study examines general characteristics of motor vehicle traffic crashes at intersections by analyzing the association of the critical reason with several crash factors such as driver's sex and age, traffic control device, critical pre-crash event, and atmospheric condition. The National Motor Vehicle Crash Causation Survey data collected at crash scenes between 2005 and 2007 is used in statistical analyses such as descriptive analysis, generalized logit model, and configural frequency analysis.

This report is a statistical analysis of several crash databases to determine the effectiveness of underride guards at preventing fatalities and injuries in crashes where a passenger vehicle impacts the rear of a tractor-trailer.

The report presents results from the 2009 National Survey of the Use of Booster Seats (NSUBS), the only probability-based nationwide child restraint survey in the United States that observes restraint use and interviews an adult occupant to collect race, ethnicity, and other data.

NHTSA conducted the National Motor Vehicle Crash Causation Survey (NMVCCS) to collect on-scene information on several crash factors, including the ones related to driver inattention. The NMVCCS data was used in this study to look at two facets of distracted driving, namely distraction from sources within the vehicle and non-driving cognitive activities, as associated factors.
