MO HB1423

Repeals and re-enacts section 304.670, RSMo to regulate traffic law enforcement data collection by highway patrol and local law enforcement agencies.

Requires collection and maintenance of traffic enforcement information including number of stops, citations/warnings issued, driver demographics (race, ethnicity, age, gender), alleged violations, searches conducted, contraband found, arrests made, and property seized.

Mandates highway patrol to conduct analyses of collected data to determine whether law enforcement officers are using profiling in enforcement activities.

Prohibits highway patrol, local law enforcement agencies, and National Highway Traffic Safety Administration employees from collecting breath, blood, or saliva samples from motorists at roadblocks, vehicle checks, or checkpoints for use in transportation-related research studies or surveys.

Exempts roadblocks, vehicle checks, and checkpoints from data collection requirements unless the stop results in a warning, search, seizure, or arrest.
