Samenvatting
Using data gathered through a self-administered survey of Florida high school juniors and seniors in 1996 and 1998, this study examined teens' reported attitudes and behaviours before and after the state's Zero Tolerance law took effect on January 1, 1997. Decreases occurred in reported driving when drinking and reported riding with friends who were drinking. Teen support for the law increased substantially. Significant changes occurred more often for males and for teens in urban and suburban, as opposed to rural, counties.
