An analysis was conducted to determine what effect California's change to a primary safety belt law had on safety belt use among nighttime weekend drivers.
Observations of 18,469 drivers in 2 California communities were made during voluntary roadside surveys conducted every other Friday and Saturday night from 9 PM to 2 AM for 4 years.
Rates of safety belt use rose from 73.0% to 95.6% (P < .0005). For drivers with blood alcohol concentrations of 0.10 or higher, rates rose from 53.4% to 92.1% (P < .0005).
Because substantial improvement in safety belt use was seen even in a group of high-risk drivers, the injury reduction benefits of this law may be high.
进行一项分析，以确定加利福尼亚州改为主要安全带法律对夜间周末驾驶者安全带使用情况产生了何种影响。
在为期4年的时间里，每隔一周的周五和周六晚上9点至凌晨2点进行自愿路边调查，对加利福尼亚州2个社区的18469名驾驶者进行观察。
安全带使用率从73.0%升至95.6%（P < .0005）。对于血液酒精浓度为0.10或更高的驾驶者，使用率从53.4%升至92.1%（P < .0005）。
由于即使在一组高危驾驶者中也观察到安全带使用情况有显著改善，该法律在减少伤害方面的益处可能很大。
