The Texas Transportation Institute has conducted a probability-based survey to estimate safety belt and motorcycle helmet use in Texas since 1992. The purpose of the survey was to determine eligibility for participation in the grant program in Section 153 of Title 23, United States Code. This section allowed the Secretary of Transportation to award grants to states that have safety belt and motorcycle helmet use laws during the first year of the program, and to award grants during the second the third years of the program to states that achieved specified rates of compliance. The National Highway Traffic Safety Administration (NHTSA) issued guidelines and provided funding for the observational survey described herein. Revised guidelines were issued in 1999 in which NHTSA again set forth eligibility criteria for Section 157 incentive grant monies. The following is a description of the 2000 sample design survey procedures, and results of the Texas survey conducted from May 13 through June 16, 2000. (Author/publisher)
