The “100 Deadliest Days” is the period between Memorial Day and Labor Day when fatal crashes involving teen drivers spike sharply. This period gets its name because school is out, more inexperienced teens are on the road, and summer freedom leads to riskier driving habits.
Your teen is likely spending more time driving at night, traveling with friends, and taking longer trips without supervision. These conditions combine to create a level of danger that is significantly higher than any other time of year.
Missouri Teen Crash Statistics
Car crashes are the number one cause of death for Missouri teens, and that risk climbs every summer. MoDOT and AAA warn that teen driver fatalities increase during the 100 Deadliest Days.
The numbers behind Missouri teen crashes paint a sobering picture:
- Speeding is a leading factor: Half of teen drivers involved in fatal crashes were driving too fast for conditions.
- Seatbelts save lives: The majority of teens killed in crashes were not wearing one.
- Summer amplifies everything: Teen crash rates rise roughly 20 percent during summer months compared to the school year.
These are not random accidents. They are predictable, and in most cases, preventable.
Why Summer Puts Teen Drivers at Higher Risk
Inexperience is the root cause of most teen crashes. New drivers simply do not have the instincts to react to sudden hazards like a car cutting them off or a wet road that reduces stopping distance.
Several specific risk factors peak during the 100 Deadliest Days:
- Distracted driving: Distracted driving is any activity that pulls attention away from the road, including texting, eating, adjusting music, or managing passengers. Teens are especially vulnerable when friends are in the car.
- Speeding: Without the pressure of getting to school on time, teens often drive faster and take more risks on open summer roads.
- Drowsy driving: Teen sleep cycles shift later in the summer, meaning many teens are driving while tired, especially late at night.
- Impaired driving: Underage drinking increases at summer parties, and teens may get behind the wheel or ride with someone who has been drinking.
- Low seatbelt use: Short trips to the pool or a friend’s house lead teens to skip buckling up, which dramatically increases the chance of a fatal injury in a crash.
Each of these risks is serious on its own. When they combine on a Friday night in July, the results can be devastating.
Missouri’s Teen Driving Laws for Summer
Missouri uses a Graduated Driver License system, or GDL, to phase in driving privileges as teens gain experience. This system is designed to limit exposure to the most dangerous driving situations until teens are ready.
Here is how the three stages work:
| License Stage | Age | Passenger Limit | Nighttime Restriction |
| Instruction Permit | 15+ | Licensed driver 21+ required at all times | Supervised only |
| Intermediate License | 16 to 17 | First 6 months: 1 unrelated passenger under 19; after: 3 max | No driving 1 a.m. to 5 a.m. |
| Full License | 18+ | No restrictions | No restrictions |
These restrictions matter most during the 100 Deadliest Days, when teens are most likely to be out late with multiple friends in the car. Enforcing these rules at home, even when your teen pushes back, is one of the most effective ways to keep them safe.
Parent Steps That Reduce Risk Right Now
Research consistently shows that parents are the single biggest influence on teen driving behavior. What you do, and what you allow, shapes how your teen drives when you are not watching.
Set Clear Rules About Night Driving and Passengers
Enforce the GDL restrictions and add your own family rules on top of them. Limiting who can ride in the car and setting a firm curfew reduces your teen’s exposure to the highest risk situations.
Model Safe Driving Every Trip
Your teen copies what they see you do. Buckle up every time, put your phone away before you start the car, and obey the speed limit. These habits are contagious.
Create a Safe Ride, No Questions Asked Plan
Tell your teen they can call you for a ride home at any time, no punishment, no lecture that night. Knowing they have a way out makes it more likely they will ask for help instead of getting in a car with an impaired driver.
Practice on Risky Roads and at Risky Times
Take your teen out to practice highway merging, driving in the rain, and navigating rural two-lane roads at dusk. Building experience in controlled situations prepares them for moments when you are not there.
Use Technology to Reduce Distraction
Set their phone to “Do Not Disturb While Driving” mode before they leave. Teen driver monitoring apps can also track speed, location, and hard braking, giving you real-time insight into how they are driving.
What to Do After a Teen-Involved Crash
Even the most careful families can face a crash. If your teen is involved in an accident, the steps you take in the first few hours matter enormously, both for their health and for any future legal claim.
Call 911 and Get Medical Care Right Away
Call for emergency help even if your teen says they feel fine. Adrenaline masks pain, and injuries like concussions or internal bleeding may not be obvious at the scene.
Document the Scene Before Leaving
Take photos of all vehicles, road conditions, skid marks, traffic signs, and license plates. This evidence can be critical later when determining who was at fault.
Gather Information from Everyone Involved
Collect names, phone numbers, and insurance details from every driver. Ask any witnesses for their contact information before they leave the scene.
Report the Crash but Protect Your Words
Notify your insurance company promptly. However, do not give the other driver’s insurance company a recorded statement before speaking with our skilled car accident lawyers. Adjusters are trained to use your words against you.
Save Every Document and Record
Keep all medical bills, repair estimates, and prescription receipts. Save any data from driving apps, text logs, and call records that could show what happened leading up to the crash.
Liability and Insurance After a Teen Crash in Missouri
Missouri is an at-fault state. This means the driver who caused the crash is responsible for paying damages, and that driver’s insurance company should be writing the check.
Missouri also follows a pure comparative fault system. This means your compensation is reduced by whatever percentage of fault is assigned to your teen, but you can still recover money even if your teen was mostly at fault.
Two legal concepts can also make parents financially responsible for a teen’s crash:
- Family purpose doctrine: This rule holds parents liable when a teen causes a crash while using the family vehicle for a family purpose, like running an errand or going to school.
- Negligent entrustment: This applies when a parent knowingly lets an unfit or unlicensed driver use the car. If you knew your teen was impaired, unlicensed, or had a history of reckless driving and handed over the keys anyway, you may share liability.
Insurance companies often default to blaming the teen driver. They use age and inexperience as a reason to deny or minimize claims, even when another driver was clearly at fault. This is exactly why having an experienced Missouri car accident lawyer on your side early makes a real difference.
Missouri Teen Driver Safety Resources
You do not have to navigate teen driving safety alone. Missouri offers several programs specifically designed to help families during the 100 Deadliest Days and beyond:
- TRACTION: A peer-to-peer teen traffic safety leadership program that trains students to influence their peers.
- First Impact: A program that walks parents through Missouri’s GDL law and how to enforce it effectively.
- B.R.A.K.E.S.: Hands-on advanced driver training for teens and parents together.
- Arrive Alive Tour: A virtual reality experience that shows teens the real consequences of distracted and impaired driving.
- SADD: Students Against Destructive Decisions chapters operate in schools across Missouri.
- Safe and Sober: An underage drinking prevention program for students and their parents.
Starting these conversations and using these resources before summer begins gives your teen a real advantage on the road.

Who Pays Medical Bills After a Crash Caused by a Teen Driver?
