Missouri Driving Laws (2026): A Complete Guide
Missouri sits in the Midwest region, with Jefferson City as its capital and Kansas City and St. Louis as its biggest cities. This guide collects the Missouri driving laws drivers ask about most, covering speed and phones to coverage, taxes, inspections and riding.
Each section below explains one law in full, with key facts and the national picture, and the figures were last checked October 25, 2026.
Missouri driving laws: speed limits
The top speed limit in Missouri is 75 mph. Rural interstates are posted at up to 75 mph and urban interstates up to 60 mph.
| Missouri: Maximum posted speed | 75 mph |
|---|---|
| Rural freeways | 75 mph |
| Interstates in cities | 60 mph |
On major roads such as I-70 and I-44, signs are frequently below 75 mph, especially through Kansas City and in work zones.
Every driver must also hold a speed reasonable for weather and traffic, even under the limit, and officers can write a ticket for that alone.
At a glance, under Missouri driving laws: max speed limit, 75 mph.
Missouri driving laws: cell phone and texting law
Only hands-free. Missouri enforces a hands-free law: motorists may not hold a phone to call, text or scroll while driving. Hands-free calls and navigation are permitted.
| Missouri: Hand-held calls | Banned |
|---|---|
| Texting behind the wheel | Banned |
| Teen phone ban | No |
Missouri's hands-free law for all motorists took effect August 28, 2025.
Under the Missouri driving laws, a phone in a mount, voice commands and one touch to pick up a call or begin a route are permitted; picking it up at a stoplight is the offense.
Bottom line, under Missouri driving laws: phone law, hands-free law.
Missouri driving laws: driving age and teen licenses
Young motorists in Missouri can get a learner's permit at 15 and a provisional license at 16, with night and passenger limits after that.
| Missouri: Permit age | Age 15 |
|---|---|
| Intermediate (provisional) license | Age 16 |
| Hours with an adult | 40 (10 at night) |

Missouri driving laws: minimum car insurance
Missouri sets a minimum of 25/50/25 in liability insurance: $25,000 for injuries to one person, $50,000 for all injuries in one accident and $25,000 for property damage. Policies must also include uninsured motorist (UM) coverage.
| Missouri: Injury limit per person | $25,000 |
|---|---|
| Bodily injury per accident | $50,000 |
| Property damage limit | $25,000 |
| Extra required coverage | UM |
| At-fault or no-fault | At-fault |
| Must you insure | Yes |
Missouri follows the at-fault system, so the at-fault driver pays for the other drivers' injuries and damage through their policy.
Required on top of liability in Missouri: uninsured motorist (UM) coverage.
A minimum policy seldom pays for a serious crash, since hospital bills and a new car can exceed $50,000 quickly.
Many agents suggest at least 100/300/100, since anything above your limits can be collected from you directly.
At a glance, under Missouri driving laws: car insurance, 25/50/25.
Missouri driving laws: car sales tax
Missouri applies a 4.225% state sales tax on vehicle purchases, and local taxes may raise the total.
| Missouri: State-level rate | 4.225% (sales tax) |
|---|---|
| Local add-ons | Yes, in some areas |
| Trade-in lowers tax | Yes |
| State tax on a $30,000 car | $1,268 |
- A $20,500 car in Missouri: around $866 in state tax
- A $35,750 car in Missouri: around $1,510 in state tax
- A $55,000 car in Missouri: around $2,324 in state tax
A trade-in lowers the Missouri driving laws: trading in a $5,000 car on a $30,000 purchase means paying roughly $1,056 compared with $1,268.
In short, under Missouri driving laws: car sales tax, 4.225%.
Missouri driving laws: car inspection and emissions
Yes. Missouri requires a safety inspection each two years and emissions testing in the St. Louis area.
| Missouri: Safety check | Every two years |
|---|---|
| Smog check | Some areas: the St. Louis area |
Safety inspections every two years apply only to vehicles more than 10 years old or with more than 150,000 miles.
The safety check in Missouri covers brakes, lights, tires, steering, glass and horn each other year.
Emissions tests on newer vehicles scan the on-board computer, which takes a few minutes; a lit check-engine light typically means a failure.
Bottom line, under Missouri driving laws: car inspection, safety + emissions.

Missouri driving laws: motorcycle helmet law
Only if you are under 26. In Missouri, motorcyclists and passengers 25 and younger are required to wear a helmet; motorcyclists 26 and older may legally ride without one. That holds on I-70 and I-44 just as it does on local streets in Kansas City.
| Missouri: Who must wear a helmet | Riders 25 and younger |
|---|---|
| Kind of law | Partial (age-based) |
| Adult riders exempt | Yes, with conditions |
Riders 25 and younger are required to wear a helmet under the Missouri driving laws; at 26 it becomes optional.
Since 2020, motorcyclists 26 and older may ride without a helmet if they can show proof of health insurance.
According to NHTSA, that helmets reduce roughly 37% of rider deaths in serious crashes, and 41% of passenger deaths.
A legal helmet carries the DOT symbol on the back; thin novelty shells without it do not count.
