Upon conviction for particular traffic offenses, some drivers might receive a penalty of license revocation, and some may receive a penalty of license suspension. Because drivers in the latter group may use extra cautionin driving to protect their future driving privileges, there may be differences between the two groups of drivers with regard to traffic violationsand crashes after driving privileges are restored. This study verified the differences during the after periods of 6, 12, and 18 months using analysis of covariance test and the t-test with stratified samples based on police profiles of about 154,000 drivers in South Korea. The study found that drivers in the group whose license had been suspended committed traffic violations and caused traffic crashes less often than those whose license had been revoked in all time periods, suggesting that license suspension might be more effective in reducing subsequent traffic offenses and trafficcrashes than license revocation, which has implications in administrativesanction policies.
