Seat belt use was observed in 1,628 cars with air bags and manual belts and 34,223 cars with manual seat belts only. Sixty-six percent of drivers in cars with air bags wore seat belts compared to 63 percent of drivers in cars with manual belts only. The study found no evidence for the speculation that drivers with air bags will reduce their seat belt use because they believe an air bag alone provides sufficient protection.
在1628辆装有安全气囊和手动安全带的汽车以及34223辆仅装有手动安全带的汽车中观察了安全带的使用情况。装有安全气囊的汽车中,66%的驾驶员系了安全带,而仅装有手动安全带的汽车中这一比例为63%。该研究没有发现证据支持这样的推测,即装有安全气囊的驾驶员会减少安全带的使用,因为他们认为仅安全气囊就能提供足够的保护。
