Public safety. Some officials emphasize the protective purpose of OWI laws. The goal is not just punishment but prevention of harm to the driver and others. This aligns with the government’s interest in protecting citizens.

Personal responsibility. Some advocates believe OWI laws reinforce accountability. The driver is held responsible for their decision to operate a vehicle while impaired. This reflects societal expectations about responsible behavior.

Rehabilitation. Many OWI statutes include treatment requirements. Courts often order substance abuse evaluations and education programs. This recognizes that impairment can stem from addiction rather than mere negligence.
