JEFFERSON CITY — Missouri Gov. Mike Kehoe is set to sign a handful of public safety initiatives into law Thursday, including tougher drunken driving rules, age verification requirements on pornography websites, and an automatic expungement program for some lower-level crimes.

In a ceremony set for Thursday, Kehoe is scheduled to approve 20 pieces of legislation sent to him by the House and Senate in May, including a plan to require a minimum 10-year prison sentence if a vehicle crash by an intoxicated motorist causes the death of more than one person.

House Bill 1740, which will go into effect Aug. 28, also would make convicted drunken drivers financially responsible for children orphaned by wrecks they cause.

A motorist found guilty of killing more than one person while driving intoxicated would have to serve 10 years before being eligible for parole or probation. A person convicted of killing one person while driving drunk with a blood alcohol content of 0.15 or higher would be required to serve five years before parole or probation eligibility.

The sponsor, Rep. Dave Griffith, R-Jefferson City, said the measure will make roads safer. About 30% of car crash deaths nationwide involve drunken drivers, according to the National Highway Traffic Safety Administration.

In addition to harsher punishments, anyone who commits an intoxication-related traffic offense with a blood-alcohol content of 0.15 or more will have an ignition interlock device installed in their vehicle to have restricted driving privileges restored.

Current Missouri law requires a person found guilty of a second or subsequent intoxication-related traffic offense to install an ignition interlock device on any vehicle they operate before their driving privileges are reinstated.

The bill includes a provision known as Bentley and Mason’s Law, named after two children whose parents were killed in a 2021 car crash involving a drunken driver.

The provision, which already is law in six other states, would require a driver who causes the death of a parent to be on the hook for child support to a surviving spouse or relative raising the victim’s children.

The intoxicated driver would have up to one year after being released from incarceration to begin child support payments.

Kehoe also is set to sign Senate Bill 1421, which includes “Clean Slate” legislation that would automatically expunge certain misdemeanors after one year and nonviolent felonies after three years.

Sen. Brian Williams, D-University City, who sponsored the proposal, said the program could help nonviolent offenders find stable employment and housing.

The automated process, which will be run by the Missouri State Highway Patrol, is expected to be in place by Jan. 1, 2028. It would apply to people convicted of felony or misdemeanor drug possession and unlawful use of drug paraphernalia. It also would apply to such crimes as forgery, property damage and stealing. Drug trafficking convictions would not be eligible for expungement.

Another bill awaiting the governor’s signature Thursday will require pornographic websites to verify users are adults. House Bill 1839 will put in state statute what Attorney General Catherine Hanaway began enforcing in December.

The attorney general’s current rule, based on her interpretation and enforcement of existing consumer protection laws, allows porn sites themselves to verify users’ identity. The soon-to-be-law will require sites to use third-party companies.

Websites that violate the requirement could face a $10,000 daily fine, plus up to $250,000 if a minor accesses sexual material.

Identifying information of people visiting sites cannot be retained by the sites or third-party age verification companies, which are required to keep the information secure.

The Free Speech Coalition, which represents online pornography companies, said the proposal is unlikely to change the landscape for viewing porn in Missouri.

A spokesman for the organization earlier said its members already are complying with existing regulations imposed by the attorney general.
