The study reports the results of an evaluation of the 'Click it or Ticket' mobilization campaign in Michigan centered around Memorial ay of 2003. The study consisted of four survey waves: Two full statewide surveys (one conducted as Baseline before the campaign and one conducted as a Post campaign measure) and two 'mini' statewide surveys conducted to assess the media and media+enforcement components of the campaign while they were being implemented. All survey waves were conducted statewide on front-outboard occupants traveling in four vehicle types (passenger cars, sport-utility vehicles, vans/minivans, and pickup trucks). Belt use was estimated for all commercial/noncommercial vehicle types combined (the statewide safety belt use rate) for each survey wave. Additional analyses were conducted on the two full statewide surveys (Baseline and Post) because of the larger sample sizes. Statewide safety belt use was approximately 80 percent prior to the mobilization campaign and this rate did not significantly change during the media portion of the campaign. During the media+enforcement period, however, safety belt use significantly increased to about 84 percent and this significant increase was maintained during the Post survey wave. Comparison of the statewide rates between the Baseline and Post surveys showed that safety belt use increased significantly after the mobilization campaign. In addition, the use rate for the Post survey was the highest ever found in Michigan. The study results suggest that: (1) Michigan should continue to participate in the national efforts to raise safety belt use; (2) safety belt enforcement zones were successful as implemented in Michigan and should be continued; and (3) the CIOT model as implemented in Michigan was successful. |
