Samenvatting
Forty-five states and the District of Columbia have laws providing for some form of re-examination upon renewal of a driver's license. Twenty-two have mandatory re-examination requirements. Re-examination upon license renewal is authorized but not required in eighteen jurisdictions. Six states provide for re-examination only where there is reason to believe the applicant is no longer qualified. Only three of the states specifically require that all licensees submit to an eye test and a test of knowledge of traffic laws at least once every four years.
