It’s a steamy July day, and you’re on I-70, yours near the stadiums. The Royals game is over; city fans are leaving home. You’re sitting bumper to bumper in your car, your bike sits waiting, and your left hand cramps. You see an opening in the lane-dual, so why not? A valid question, but one where the answer isn’t as cut-and-dried as you might wish.
Short answer: Missouri doesn’t have a statute that says lane splitting is legal, nor does it have legislation that says lane splitting is illegal. Isn’t that annoying? That ambiguous region leaves motorcyclists guessing, and guessing costs. Speeding Ticket KC, a prominent Kansas City legal company, is all too familiar with the consequences of these stops and crashes.
So, What Is Lane Splitting?
Lane splitting is when a motorcycle rider travels between two lanes of same-direction traffic. Think of a busy church parking lot after church on Sunday. Everybody is heading toward the exit, but one person is slithering down the middle. Some say that’s disrespectful; some say it’s wise.
Lane filtering—slipping your way to the front of a red light, in between stopped cars—is a near cousin. With both methods, California has specific rules. Missouri never has, so riders there depend on vague traffic laws and hope the cop agrees. It’s a dangerous gamble.
What the Law Says (and Doesn’t)
The first is RSMo 304.015, which involves cooperative road use with other vehicles. On any highway with three or more lanes of traffic, drive as close as possible entirely within a single lane (304.015.1(1)). But what if you see something? Nothing in the clause prohibits a motorcycle from riding in the space between lanes. So in that silence, in a sense, they’ve got all the gray space.
Lawmakers did, too. As it turned out, lane-filtering bills arrived from House members in 2023, 2024, and 2025. The concept was simple: permit slow filtering of any halted traffic (say, up to 25 mph) but continue to prohibit splitting of fast-moving traffic. As of this writing, none of those bills have become law (remember – things get changed, and it’s best to make sure fast before you ride).
Gray Doesn’t Mean Safe
This contradicts being caught. It’s not about the “illegal” part – you might get cited for something not necessarily “illegal.” You can be cited by an officer for RSMo 304.012, driving in a careful and responsible manner. So picture yourself driving between two semis at 40 mph. Nobody considers that careful.
A conviction earns you points on your license under RSMo 302.302. Points can increase your insurance costs, and an excessive amount can lead to a suspension. Add speeding, and you can end up with two citations in hand.
Weary riders feel like they’re being singled out, and it’s easy to see the frustration. Cars change lanes regularly, yet it makes the news as rarely as it does. But officers don’t assess danger based on the car you drove but on your actions. After all, crawling around, parked cars at five miles an hour is not the same as weaving in traffic, and judges know that, too.
What If You Have an Accident?
You could be changing lanes and get hit by a car. Is that definitely your fault? Absolutely not. Missouri, of course, is a pure comparative fault (RSMo 537.765) state, where a jury assigns percentages of fault. If you’re 20% at fault, you’ll recover 80% of your damages.
Not so fast—not friendly to the insurance company. Adjusters love to blame the rider. While you cannot 100% blame someone for merging without looking, you also cannot blame someone who opens their door into your path. Record the police report, names of witnesses, and take pictures whenever you can. Memories don’t last long.
Ride Smart Out There
In fact, lane splitting is hazardous. Most drivers scan their mirrors for automobiles, not motorcycles. You can blame-blame all you want, but you can still make yourself forget. Remember these tendencies while you sift among stopped cars:
- Do not go faster than 10 mph in traffic.
- Keep out of traffic if moving faster than 20 mph.
- Look out for turn signals, drifting tires, and avoid blind spots.
- Dress in bright clothing and wear a helmet. Wear a helmet (RSMo 302.020) if you’re under 26.
Summer only makes it worse. It causes short tempers and sloooow lines to distract crabby drivers.
What If You Get a Ticket? Go Directly to Payment
Don’t just mail in a check. If you pay, you are pleading guilty, and you will have points on your record. Traffic lawyers in Kansas City, MO can review the stop, the officer’s notes, and what you can do next.
Speeding Ticket KC partners with riders and drivers throughout all of Kansas City and knows how these matters are handled by courts in the area. Some tickets are dropped or reduced, saving your dollars as well as your license.
The Bottom Line
Lane splitting is not illegal, but it’s not legal. That gray area makes motorcyclists vulnerable to tickets and blame battles. Ride smart, ride slow, and if you are in trouble, call a lawyer right away.
Common Questions
Is lane splitting against the law in Kansas City?
Not precisely. Missouri law doesn’t prohibit it, nor does it enable it. But you do still have the right to be ticketed for unsafe appearance riding.
In Missouri, is lane filtering legal?
State law hasn’t allowed it yet. Bills have been presented to allow slow filtering around halted traffic. So far, none have passed.
Will I get a ticket for splitting lanes?
Yes. It is considered reckless and unsafe driving under RSMo 304.012. It’s a moving violation that adds points to your license and jacks up your insurance.
If I crashed while lane splitting, am I at fault?
Not necessarily. Missouri splits fault by percentage, RSMo 537.765. If the other driver was partially to blame, you can still collect some of your damages.
Do I need an attorney for a lane splitting ticket?
Yes, if you want to protect your license and cut your insurance rate. A lawyer can evaluate the stop and negotiate reduced charges or the dismissal of the case. Don’t pay anything until you see one.
