KANSAS CITY, Mo. — A routine traffic stop is a high-stress event for any driver, but for those with autism or other communication-related disabilities, the experience can quickly devolve into a life-altering crisis. For Megan Brown, a mother from Lawrence, this abstract fear became a terrifying reality on an autumn afternoon last year. The incident, which nearly ended in tragedy, has since sparked a legislative movement that is now set to change how law enforcement interacts with the disability community across Missouri.
Ten months after a Kansas City police officer drew a sidearm on her son during a traffic stop, Brown reflects on the event with a mix of lingering trauma and profound pride. Her son, Mason Ott, now 22, is a young man with autism who has navigated life with diligence and a deep respect for rules. Yet, on that day, a simple misunderstanding regarding a traffic violation turned into a harrowing encounter that left a family questioning how their loved one could have so easily been caught in the crosshairs of a fatal mistake.
That experience is the catalyst for “Mason’s Law,” a piece of legislation enacted this past July. Named in honor of Ott, the law establishes a voluntary, confidential system that allows law enforcement to identify drivers with autism or other special needs through their license plates. By providing officers with critical context before they even approach a vehicle, the law aims to prevent the misinterpretation of non-responsive behavior as defiance or hostility, potentially saving lives and de-escalating encounters before they begin.
A Routine Stop Gone Wrong
The incident occurred around noon on the Monday before Thanksgiving last year. Ott, a high-functioning young man who graduated from Staley High School in 2022 and completed a certificate program at the University of Kansas, was driving his white 2014 Ford Escape near Maplewoods Parkway in the Northland.
According to accounts provided to his mother by law enforcement, an officer clocked Ott driving 42 mph in a 35 mph zone. For a young man known for being a “rule follower,” the infraction was an anomaly. When the officer activated his flashing lights, Ott—who had been taught to seek a safe location to pull over—initially complied. However, due to his literal interpretation of instructions, the situation spiraled.
Ott pulled over, but because he was not explicitly told to remain stationary, he proceeded to drive at a steady 35 mph toward his apartment complex about 1.5 miles away, using his turn signals throughout the duration of the short trip. There was no pursuit, no high-speed chase, and no indication of aggression. Yet, when he pulled into the parking lot of his apartment complex, the responding officer exited his vehicle with his gun drawn, shouting commands for Ott to exit the car with his hands up.
Caught in a state of sensory overload and confusion, Ott froze. He did not move, nor did he respond to the officer’s shouted commands. It was only the intervention of apartment complex employees, who witnessed the scene and frantically shouted, “Stop! Stop! He has autism,” that the tension began to dissipate. The officer, initially unaware of the driver’s condition, eventually de-escalated the situation.
For Megan Brown, the phone call that followed was a nightmare. She was working in Lawrence when she learned of the incident, and subsequent conversations with her ex-husband revealed the severity of the officer’s reaction. “I fell,” Brown recalled, describing the moment she realized how close she had come to losing her son. “There were some stairs there, and I just fell. I was burying my head in a towel and I just started bawling.”
Advocacy Born from Fear
In the weeks and months that followed, the weight of the incident did not fade. Brown began speaking with other parents in the disability community, discovering that her fear was far from unique. Lauren Ray, a Kansas City parent whose 17-year-old son, Sam, is also on the autism spectrum, found the story deeply resonant.
“She wanted to share with me Mason’s story because she was worried that Sam would have reacted the same way, which I truly believe he would have,” Ray said. “You always have that fear, as a parent, of how your child will react, whether they’re typical or atypical. But this situation never even crossed my mind. That’s why when Megan shared it, I was told, ‘We have to do something.’”
The two women turned to State Representative Chris Brown, a Republican from Clay County. Having known the representative for years—Ray noted that he had previously been her history teacher at Oak Park High School—they felt confident he would understand the gravity of the situation. Representative Brown, who had long been aware of the challenges facing families with children on the spectrum, proved to be an eager partner.
“I’ve been in the Missouri House now for six years,” Rep. Brown said. “One of the cool things about this bill is it was absent lobbyists. It was absent big business. It was literally two moms—one of the moms had an unfortunate situation with law enforcement. It was so organic. They called me up and said, ‘Hey, we can do better.’ And I was like, ‘You know what? You’re right.’”
A Model for Future Safety
The legislation, which moved through the statehouse during the early months of 2024, creates a framework for the Missouri Department of Revenue to integrate disability data into the Missouri Unified Law Enforcement (MULE) system. Under the new law, drivers can voluntarily register their status if they provide certification from a physician confirming a physical or mental health condition that impacts their ability to communicate effectively with law enforcement.
The certification requires that the physician attest the condition is likely to persist for at least five years. While the system is not yet fully operational—it is expected to be live by early 2027—it promises to provide a vital layer of information for officers. When an officer runs a license plate, they will be alerted to the presence of a communication impairment, allowing them to adjust their approach and de-escalate potential misunderstandings.
During testimony in March, supporters emphasized that the law serves a broad spectrum of needs. Lauren Ray, who has family members with hearing impairments who utilize cochlear implants, noted that the law addresses more than just autism. “If you have a medical diagnosis that would hinder how you would respond in an emergency situation, it’s just a win-win for law enforcement and for the individual,” she said.
For the families involved, the legislative victory is a significant step toward peace of mind. Mason Ott, who received no citations for the incident that sparked the law, expressed a simple, pragmatic view: “It will be really helpful.”
Until the digital system is fully integrated, many parents, including Megan Brown, continue to rely on manual measures, such as “Autistic driver” bumper stickers. While these serve as a temporary solution, Brown admits they are imperfect; she worries that highlighting her son’s condition could make him a target for those looking to exploit his vulnerabilities.
As the state moves toward the 2027 implementation date, the focus has shifted to raising awareness and ensuring that the law is effectively utilized by both the public and law enforcement. For Representative Brown, the process has been a testament to the power of constituent-led change. He believes that by providing officers with better information, the state is fostering a safer environment for everyone on the road.
For Megan Brown, seeing her son’s name attached to a law designed to prevent other families from experiencing her heartbreak is a deeply emotional milestone. “I never expected it to be named after him,” she said. “When Chris Brown said, ‘We’re going to name it Mason’s Law,’ I just started crying. I just thought it was amazing.”
