The National Police Agency on Wednesday announced a drafted amendment to current traffic laws that would increase prison terms and fines for some violations.

The move came in response to complaints from bereaved families of traffic accident victims who say the current laws are too lenient for offenses such as driving without a license and drunk driving.

The draft also proposes heavier penalties, such as increased fines, for less serious violations such as illegal parking. The amendment would, however, ease the burden on drivers somewhat by extending the basic renewal period for driver's licenses to five years from the current three years.
