MO HB1742

Creates new tracking system (DWITS) requiring law enforcement, prosecutors, and courts to enter information on intoxication-related traffic offenses, with state highway patrol gathering data and governor able to withhold state funds from non-compliant agencies.

Elevates first-offense driving while intoxicated to class A misdemeanor when blood alcohol content is 15-hundredths of one percent or more by weight, with mandatory 90-day revocation followed by 275-day restricted driving privilege.

Prohibits persons convicted of DWI with blood alcohol content of 15-hundredths or more from obtaining limited driving privileges for 90 days, then limited to 275 days of restricted driving with ignition interlock device requirement.

Requires ignition interlock device installation on all vehicles for persons with prior alcohol-related enforcement contacts seeking license reinstatement or restricted driving privileges.

Prohibits persons who plead guilty to DWI or excessive blood alcohol content and receive suspended imposition of sentence from later withdrawing their plea.
