MS HB43

Creates a new crime of "child endangerment" for persons 21 years or older who drive under the influence of alcohol or drugs (in violation of implied consent law) while carrying a passenger under 21 years old.

First violation of child endangerment is a misdemeanor punishable by a fine up to $1,000 and/or up to 1 year imprisonment; second or subsequent violations are felonies punishable by a fine up to $5,000 and 1-5 years in the Department of Corrections.

Requires ignition interlock device use for child endangerment violations and prohibits sentence reductions, plea bargains, or diversion programs; also mandates in-depth diagnostic assessment and alcohol/drug treatment completion if needed.

Amends Section 63-11-30 to lower the blood alcohol concentration threshold from 0.08% to 0.05% for second or subsequent DUI offenses for persons above legal drinking age.

Makes hardship driving privilege reductions unavailable to persons convicted under the new child endangerment provision.
