Evaluation of the Washington Nighttime Seat Belt Enforcement Program

The Washington Traffic Safety Commission (WTSC) and the National Highway Traffic Safety Administration (NHTSA) conducted a high-visibility Nighttime Seat Belt Enforcement (NTSBE) program in Washington. The two-year program followed the basic Click It or Ticket (CIOT) model by using highly visible enforcement combined with increased paid and earned media about the enforcement but applied its efforts during the nighttime rather than the daytime hours. Public awareness surveys showed that 70% of Washington motorists had read, heard, or seen the program, and the message reached 18- to 34-year-old male drivers, the primary high-risk group. Observations at 40 sites across the State showed a statistically significant increase in night belt use. Night belt use began at 95% before the NTSBE program, and it peaked at 97% in July 2009. Daytime belt use remained high, despite focusing all CIOT efforts during the nighttime hours. Time-series analysis of fatality data showed that after the NTSBE campaign there was a reduction of 3.4 nighttime fatalities per month in Washington. Belt use among fatally injured occupants in both daytime and nighttime increased after NTSBE, but the increase was not statistically significant when compared to all primary law States. The NTSBE program positively affected driver awareness, increased observed nighttime seat belt use, and did not decrease the daytime use rate.
