Drivers who were free of collisions and convictions over a one year prior period were sent a letter notifying them of a 12 month license extension issued as a "reward" for this accomplishment. They were also told that at the end of the following year should their records again be clean, they would be recontacted and given a second extension. The results of this Reward Program indicated no reliable influence on subsequent traffic convictions and various detrimental effects on subsequent collisions compared to uncontacted controls. Drivers having one of more prior entries were involved in an incentive program. These drivers were sent a letter describing their eligibility for a 12 month license extension which would be granted provided their records remained free of collisions and convictions over the subsequent year. The results of this Incentive Program indicated no significant effects on subsequent convictions, but various beneficial effects on subsequent collisions compared to controls.
