Missouri’s Graduated Driver License law requires teen drivers to work through three stages before they can drive without restrictions.
At 15, your teen needs a supervising adult in the seat next to them, at 16 they can drive alone under a curfew and passenger limits, and at 18 all restrictions lift.
Handing your teen the keys is stressful enough without also having to track curfew hours, passenger limits, and supervised-driving requirements on top of it, and one missed detail can set their progress back.
Police rarely catch GDL violations in real time, which means enforcing these rules falls squarely on you. If your teen is ever in a crash while breaking a GDL rule, the other driver’s insurance company will find out and use it to shift blame onto your family.
In this article, you will discover every stage of Missouri’s GDL program, the specific rules that apply at each license level, the penalties for violations, and how Beck & Beck Missouri Car Accident Lawyers can help if a teen driver, yours or someone else’s, was involved in your crash.
What Is Missouri’s Graduated Driver License Law?
Missouri’s Graduated Driver License (GDL) law is a three-stage licensing system that phases in driving privileges for first-time drivers between ages 15 and 18. Instead of handing a new driver full freedom on day one, the law builds their independence gradually, and keeps real restrictions in place until they’ve earned the right to drive without them.
The three stages are:
- Instruction Permit (Age 15): Your teen can only drive with a qualified supervising adult in the front seat at all times.
- Intermediate License (Age 16): Your teen can drive alone for the first time, but with curfews and passenger limits in place.
- Full Driver’s License (Age 18): All GDL restrictions are lifted, and your teen drives with the same freedom as any adult.
You cannot skip stages, each one has its own requirements that must be met before moving up.
What Are the Permit Rules at Age 15?
The Instruction Permit is the first stage, a supervised-only driving credential that lets your teen practice behind the wheel for up to 12 months. To get one, they must pass three tests at a Missouri State Highway Patrol (MSHP) driver examination station:
- A vision test to confirm minimum eyesight standards
- A road sign test to verify they can identify common traffic signs
- A written knowledge test covering Missouri traffic laws and safe driving practices
Who Can Supervise a Permit Driver?
A qualified adult must be in the front passenger seat every single time your teen drives on a permit. There are no exceptions to this rule.
People who can legally supervise a permit driver include:
- A parent or legal guardian with a valid license
- A grandparent with a valid license
- A certified driving instructor
- Any licensed driver who is 25 or older, with written parental permission
A parent or guardian must also sign a permission statement at the license office when the permit is issued.
How Many Supervised Hours Does a Teen Need?
Before your teen can advance to an intermediate license, you must certify that they completed at least 40 hours of supervised driving practice, with at least 10 of those hours logged at night, defined as 30 minutes after sunset to 30 minutes before sunrise.
You’ll track every session on the official driving log, Form 4901, which you sign and submit when it’s time to move up.
What Are the Intermediate License Restrictions at 16?
Once your teen turns 16 and has held their permit for at least 182 days, they can apply for an Intermediate License, the first license that allows them to drive alone. It’s a big milestone, but it comes with real restrictions that are strictly enforced.
| License Stage | Minimum Age | Key Restriction |
| Instruction Permit | 15 | Supervised driving only |
| Intermediate License | 16 | Curfew and passenger limits |
| Full Driver’s License | 18 | No GDL restrictions |
What Are the Curfew Hours for Teen Drivers?
Intermediate license holders are prohibited from driving between 1:00 a.m. and 5:00 a.m.. The late-night hours carry the highest crash risk for new drivers, and this rule keeps your teen away from those conditions.
There are four exceptions to the curfew:
- Driving directly to or from a school activity
- Driving directly to or from work
- Driving because of an emergency
- Driving with a licensed adult over 21 in the front seat
What Are the Passenger Limits for Teen Drivers?
Passengers are one of the biggest distractions for a new driver, so Missouri law places firm limits on who your teen can carry.
- First 6 months: No more than one passenger under 19 who is not an immediate family member
- After 6 months: No more than three passengers under 19 who are not immediate family members
Immediate family members, parents, grandparents, and siblings, are always allowed in the car, regardless of how many there are.
What Are the Seat Belt Rules?
Every person in the vehicle must wear a seat belt when a teen with an intermediate license is driving, in every seat, every time. This is stricter than the requirement for adult drivers.
What Is the Phone Rule for Teen Drivers?
Missouri makes it illegal for any driver under 21 to use a handheld cell phone while driving, including texting, calling, or using any app. Distracted driving is one of the leading causes of crashes for new drivers, and this rule exists to protect them and everyone around them.
What Is the Zero Tolerance Alcohol Rule?
Missouri’s “Abuse and Lose” law applies a zero-tolerance policy to drivers under 21. Any detectable Blood Alcohol Content (BAC) above .020%, even a trace, can trigger a license suspension. There is no minimum threshold where a young driver is considered safe.
When Does a Teen Get a Full License?
At 18, your teen can graduate to a full, unrestricted driver’s license. The curfews, passenger limits, and other GDL restrictions no longer apply.
What Are the Requirements for a Full License?
To qualify for a full license, your teen must:
- Be at least 18 years old
- Hold a valid intermediate license
- Have no alcohol-related convictions in the past 12 months
- Have no traffic convictions in the past 12 months
What Tests Are Required for a Full License?
If their intermediate license is still valid, your teen won’t need to retake the written or driving skills tests. They will need to pass the vision and road sign tests again before the full license is issued.
What Happens After a GDL Violation?
Breaking a GDL restriction isn’t a minor issue, it carries real consequences that can set your teen’s driving progress back significantly.
What License Penalties Apply?
A traffic conviction during the GDL period resets the 12-month clean-record clock your teen needs to advance to the next license stage. Enough points on their record can result in a full suspension or revocation of their driving privileges.
How Does a GDL Violation Affect an Insurance Claim?
If your teen is in a crash while breaking a GDL rule, driving after curfew, carrying too many passengers, the other driver’s insurance company will find out, and they will use it against you. Insurance adjusters are trained to delay, deny, and minimize payouts, and a GDL violation hands them exactly the argument they need to claim your teen shares the blame, even when someone else caused the crash.
A pattern we see often in Missouri crashes involving teen drivers is an insurer treating any GDL violation, even a minor one like one extra passenger, as if it were the direct cause of the crash rather than an unrelated technical infraction. We challenge that leap every time it isn’t actually supported by the facts of the collision.
How Can Parents Enforce Missouri GDL at Home?
Police can’t tell a driver’s age from the road, and they rarely catch GDL violations in real time. That puts the responsibility for enforcing these rules squarely on you.
What Rules Should Parents Set in the First Six Months?
The six months after your teen gets their intermediate license are statistically the most dangerous stretch of their entire driving career. Set house rules that go further than the law requires:
- No passengers at all: Even one friend in the car dramatically increases the risk of a serious crash for a brand-new driver.
- No night driving: Keep independent nighttime trips off the table until they’ve built real daytime experience.
- Essential trips only: Limit driving to school, work, and familiar routes, no recreational cruising with friends.
Where Can Parents Find Official GDL Resources?
The Missouri Department of Revenue maintains a full GDL overview on their website. For test requirements and examination station locations, visit the Missouri State Highway Patrol website. Missouri’s First Impact program also offers a free 90-minute course for parents and new drivers focused specifically on crash risk.
Were You Hurt by a Teen Driver in Missouri?
Getting hit by an inexperienced driver isn’t just an accident, it’s someone else’s failure to follow the rules crashing straight into your life. Now you’re hurt, dealing with bills, and trying to get answers from an insurance company that’s suddenly very hard to reach.
Whether a teen driver hit you or your family member was injured by someone else’s negligence on the road, you need someone who knows exactly how to fight back.
In our experience representing clients hurt by inexperienced drivers in Missouri, a teen driver’s own insurer sometimes tries to shift responsibility onto the parent who supervised the permit stage, even when the crash happened well after the teen was licensed to drive alone. We keep the claim focused on who was actually driving and what they did.

Frequently Asked Questions
Can a 15-Year-Old Drive Alone to School?
No. A teen on an instruction permit cannot drive alone under any circumstances, including to and from school. A qualified supervising adult must be in the front passenger seat every time they get behind the wheel.
Can a Sibling or a 21-Year-Old Friend Supervise a Permit Holder?
A sibling can supervise only if they are at least 25 years old and have written parental permission. A 21-year-old friend does not meet the legal minimum age requirement of 25 to serve as a supervisor.
Can a Teen Use a Mounted Phone for GPS?
While the law allows hands-free, mounted device use for navigation, the safest practice for a new driver is to set the destination before leaving and rely entirely on voice prompts, glancing at a screen, even briefly, is a serious risk.
Do Out-of-State Teen Drivers Have to Follow Missouri GDL Rules?
Yes. When driving in Missouri, teen drivers from other states must follow Missouri’s GDL laws, including curfew hours and passenger restrictions, regardless of what their home state permits.
Who Counts as Immediate Family Under the Missouri Passenger Rule?
Immediate family includes parents, stepparents, grandparents, and siblings. Friends, cousins, and significant others do not count as immediate family under Missouri law, no matter how close the relationship.
What Happens if a Teen Is in a Crash While on a Permit?
Fault is determined the same way as in any other accident. If your teen was driving without a supervisor or otherwise violating a permit condition, it can seriously complicate your insurance claim and result in license penalties on top of the crash itself.
