Samenvatting
The Colorado Occupant Protection Project COPP intervention provided police with brief instruction concerning the importance of citations for drivers' failure to use child safety seats and special coupons to accompany citations. Coupons were exchangeable by drivers for a safety seat and brief training in its use, plus a waiver of the $50 citation fine. Over 4,5 yeats of archival records were employed, using an ABA design and a comparison community to evaluate the program.
