Effects of license revocation on drunk-driving offenders.

Revoking or suspending the licenses of persons convicted of driving while intoxicated has often been claimed to be uniquely effective in reducing subsequent dangerous driving, as indexed by crashes and violations. This finding holds despite the impression that many suspended and revoked drivers continue to drive illegally. The research described here inquires into the operation of license actions. It uses intensive personal interviews with offenders to obtain information concerning the nature and amount of illegal driving and the effects of license deprivation on employment and other aspects of the offenders' lives.
