Since then, the number tended to decline and reached 89,781 persons (a drop of 14.6% from the previous year)in 2000.
  Meanwhile, the number of crackdowns on juvenile violations of Road Traffic Law peaked at approximately 1.94 million cases in 1985. Since then, however, the number tended to decline. The number of crackdowns in 2000 was 641,802, of which 553,935 cases (86.3%) were notified as non-penal violations. With respect to percent distributions of types of violation in penal cases by juveniles, driving without a license had the largest share (43.4%) in the total number of cases, followed by speeding (24.7%), driving while intoxicated (7.4%), and seating capacity violations (5.5%). As compared with adult cases, the percentage of those driving without a license was significantly higher (5.2%for adults) among juvenile cases.
