Appendix Two Cancer Risk Assessment for Persons Involved in Application of Chlordimeform as a Pesticide to Cotton Fields in California... 

It is apparent that self regulation for people who retain their license is at least as effective as formal licensing tests. This was inadvertently demonstrated by Henessy and Janke (2005) in their study on California drivers. They found that "compared to elder renewal license applicants who were assessed as somewhat functionally limited, elder renewals assessed as extremely functionally limited were more likely to fail a structured road test, but less likely to have been crash involved in the last three years". The paradoxical implications are similar to those from Hakamies-Blomqvist et a/, s (1995) study people that are most likely to be relicensed may be more dangerous on the road than those whose license would most likely be revoked. Of course, the reason for this seeming paradox is that in the driving tests the two groups had to perform the same drives, whereas in real life the less functional people tend to restrict themselves to the point that they are actually less at risk.
