California Teen Passenger Deaths and Injuries Drop as Graduated Driver License Law Marks Second Anniversary.Business Editors and Automotive Writers LOS LOS Length of stay, see there ANGELES--(BUSINESS WIRE)--Sept. 14, 2000 Teen passenger deaths and injuries when 16-year-olds are behind the wheel declined 21 percent statewide from 1998 to 1999, according to according to prep. 1.

A new Auto Club analysis of California California (kăl'ĭfôr`nyə), most populous state in the United States, located in the Far West; bordered by Oregon (N), Nevada and, across the Colorado River, Arizona (E), Mexico (S), and the Pacific Ocean (W). teen crash data reveals dramatic reductions in deaths and injuries among teens as the state marks the second anniversary of its Graduated Driver License (GDL GDL Graduated Driver (s) License GDL Graduated Driver Licensing GDL Gas Diffusion Layer GDL Graduate Diploma in Law (UK) GdL Gruppo di Lavoro (Italian) ) system. "This analysis is especially important since California was the first state in the U.S. to adopt a meaningful passenger restriction," said Steve Bloch, Ph.D., the Auto Club's senior researcher. "It now seems clear that this type of restriction can save lives and reduce injuries. The 21 percent decline in deaths and injuries over the first 11 months of 1999 is substantial, especially when compared to passenger deaths and injuries for 18- to 19-year-old drivers who weren't affected by GDL. In that group, teen passenger deaths and injuries increased 5 percent." Reductions in 1999 are particularly noteworthy because in the years before GDL, teen passenger deaths and injuries for 16-year-old and 18- to 19-year-old drivers changed at very similar rates, explained Bloch.

It showed that the number of fatal and injury crashes where 16-year-old drivers were at-fault declined 20 percent from 1998 to 1999. By comparison, at-fault crashes of 18-year-olds increased 6 percent. Prior to the GDL law, average annual changes in at-fault crashes for 16- and 18-year-old drivers were nearly identical -- less than 1 percent per year. "These findings show quite conclusively con·clu·sive adj. Serving to put an end to doubt, question, or uncertainty; decisive. See Synonyms at decisive. con·clu  sive·ly adv. that GDL had its
intended effect of reducing teen crashes," said Bloch. "Older
teen drivers who obtained their licenses before GDL did not show the
kind of reductions that the affected 16-year-olds did."Bloch cautioned that despite his analysis, it's not clear exactly how GDL works to reduce crashes. California's reduction in crashes could be a result of decreased teen driving or licensing or due to increased driving practice and better teen driving.

"More research is needed to determine why GDL had the effect it did on teen crashes and teen passenger deaths and injuries." The Graduated Driver License law requires teens under 18 to hold their learner's permit Noun 1. learner's permit - a document authorizing the bearer to learn to drive an automobile license, permit, licence - a legal document giving official permission to do something for at least six months before obtaining a provisional Temporary; not permanent.

During this time, they must spend at least 50 hours behind the wheel practicing with a parent or guardian. Once they earn provisional licenses, they are prohibited from carrying passengers under age 20 for the first six months unless a licensed driver at least 25 is present. For the first year, they may not drive from midnight to 5 a.m. The Auto Club co-sponsored the bill that became the GDL law. Although the law went into effect in July 1998, the first 16-year-olds obtained provisional licenses under the law in January 1999. The Auto Club provides a free brochure, "Teen Drivers: A Guide to California's New Graduated Driver License," at its district offices throughout Southern California Southern California, also colloquially known as SoCal, is the southern portion of the U.S. state of California. Centered on the cities of Los Angeles and San Diego, Southern California is home to nearly 24 million people and is the nation's second most populated region, and on its Web site at www.aaa-calif.com under "member services."

Since then, AAA clubs in states throughout the nation have lobbied for GDL. To date, 31 states and the District of Columbia District of Columbia, federal district (2000 pop. 572,059, a 5.7% decrease in population since the 1990 census), 69 sq mi (179 sq km), on the east bank of the Potomac River, coextensive with the city of Washington, D.C. (the capital of the United States). have adopted a three-stage GDL system. Eleven other states have adopted some components of such a system but do not fully incorporate the three stages. The national AAA goal is to have a GDL system in all 50 states. The Automobile Club of Southern California, the largest affiliate of the AAA, has been serving members since 1900. Today, the Auto Club's members benefit by the organization's roadside assistance, insurance services, travel agency, financial products, automotive pricing, buying and financing programs, automotive testing and analysis, trip planning services, highway and transportation safety programs and legislative advocacy. Information about these products and services is available on the Auto Club's Web site at www.aaa-calif.com.
