Key Takeaways

  • Call 911 immediately — motorcycle accidents produce severe injuries. Missouri law requires reporting any accident involving injury, death, or significant property damage.
  • Missouri has a 5-year statute of limitations for most personal injury claims (Mo. Rev. Stat. § 516.120). Wrongful death claims must be filed within 3 years (Mo. Rev. Stat. § 537.100).
  • Missouri follows pure comparative negligence (Mo. Rev. Stat. § 537.765) — you can recover even if you share fault, with no bar threshold. Your recovery is reduced by your percentage of responsibility.
  • Missouri relaxed its universal helmet law in 2020 (SB 147). Riders 26 and older may ride without a helmet if they meet specific conditions — but not wearing a helmet can be used as evidence to reduce your recovery if you suffer a head injury.
  • Motorcyclists face extreme bias from insurance adjusters and juries. The insurance company will look for any reason to blame you — lane position, speed, visibility, helmet use. Having an attorney protects you from these tactics.
  • Most St. Louis motorcycle accident attorneys offer free consultations and work on contingency. You pay nothing unless they win your case.

Check for injuries and call 911

Motorcycle crashes produce devastating injuries. Without the protective steel frame of a car, riders absorb the full force of impact. Road rash, broken bones, traumatic brain injuries, spinal cord injuries, and internal organ damage are far more common in motorcycle crashes than in car collisions.

Call 911 immediately. The St. Louis Metropolitan Police Department or Missouri State Highway Patrol will respond and create an official crash report. If you are conscious and able, do not remove your helmet until EMS arrives — moving your head or neck after a crash could worsen a spinal injury.

Missouri recorded 138 motorcyclist fatalities in 2024, accounting for 15% of all traffic deaths despite motorcycles representing just 2.6% of registered vehicles. St. Louis, St. Charles, and surrounding counties consistently rank among the highest in the state for motorcycle crashes. You are not alone, and there is a clear path forward.

Move to safety if you can

If you can move safely, get yourself and your motorcycle out of the travel lanes. St. Louis's interstate system — I-70, I-64, I-44, and I-55 — carries fast-moving traffic through tight corridors, and a disabled motorcycle in a traffic lane creates severe secondary crash risk.

If you cannot move, stay as still as possible and wait for emergency services. If you can, activate your hazard lights or ask a bystander to direct traffic around you. The Poplar Street Bridge and the I-70/I-270 interchange are particularly dangerous areas to be stopped in traffic.

Do not attempt to stand up your motorcycle or assess damage if you are in pain. Your health is more important than your bike. EMS will document the scene and help you safely.

3

Document the scene thoroughly

If you are physically able, use your phone to photograph everything: the motorcycle from multiple angles showing damage, the other vehicle(s) involved, the road surface (gravel, potholes, oil, debris), skid marks, traffic signals, your riding gear (helmet, jacket, gloves showing impact damage), and any visible injuries.

Exchange information with the other driver: full name, phone number, insurance company and policy number, driver's license number, and license plate number. If there are witnesses, get their contact information. Witness testimony is especially valuable in motorcycle cases because drivers often claim they "didn't see" the motorcycle.

Do not apologize or admit fault. Under Missouri's pure comparative negligence rule (Mo. Rev. Stat. § 537.765), your compensation is reduced by your percentage of fault. Insurance adjusters are trained to look for statements they can use against motorcyclists — even a simple "I'm sorry" can be twisted into an admission of fault.

4

File a police report

Given the severity of most motorcycle crashes, police will typically respond and generate a report automatically. If for any reason they do not, Missouri law requires drivers to file a written crash report if the accident involved injury, death, or property damage exceeding $500.

To obtain a copy of your St. Louis Police crash report, request it from the SLMPD Records Service Center at 1915 Olive Street, 1st Floor, St. Louis, MO 63103, phone (314) 444-5551. The fee is $6 to $10. For crashes in St. Louis County, contact the St. Louis County Police at 7900 Forsyth Boulevard, Clayton, MO 63105, phone (314) 615-5317.

The police report should document the other driver's statements, any citations issued, road conditions, and witness information. Review it carefully — errors in police reports happen, and they can affect your claim. Your attorney can request corrections if needed.

5

See a doctor within 72 hours

Even if you walked away from the crash, see a doctor within 72 hours. Motorcycle accident injuries frequently have delayed onset: concussions may not produce symptoms for days, internal bleeding can be slow, and adrenaline masks fractures and soft tissue damage. A prompt medical evaluation creates the documented link between the crash and your injuries that your claim requires.

Barnes-Jewish Hospital at 1 Barnes Jewish Hospital Plaza is St. Louis's premier Level I trauma center. SSM Health Saint Louis University Hospital at 1201 South Grand Boulevard is a second Level I trauma center in the city. For crashes in St. Louis County, Mercy Hospital St. Louis at 615 South New Ballas Road is a Level I trauma center at the I-270 and I-64 interchange.

Motorcycle injuries often require extended treatment: orthopedic surgery for fractures, plastic surgery for road rash, neurological care for brain injuries, and months of physical therapy. Keep every medical record, receipt, and prescription — these documents directly determine the value of your claim.

6

Do NOT give a recorded statement to the other driver's insurance

Motorcycle accident victims face a unique challenge: bias. Insurance adjusters and juries frequently assume motorcyclists are reckless, speeding, or weaving through traffic. The other driver's insurance company will exploit this bias to argue you share fault — reducing your recovery under Missouri's comparative negligence rule.

You are not legally required to give a recorded statement. If the other driver's insurer calls, say: "I'm not prepared to give a statement at this time." Do not discuss the crash, your injuries, your riding experience, or whether you were wearing a helmet. All of this information can be used against you.

Missouri is an at-fault state with required insurance minimums of 25/50/25 for auto and 25/50/10 for motorcycles. Missouri mandates uninsured motorist coverage of $25,000/$50,000 on every auto policy — it cannot be waived. Given that roughly 14% to 21% of Missouri drivers are uninsured, this coverage is critical for motorcyclists.

Understand Missouri's helmet law and how it affects your claim

In 2020, Missouri repealed its universal helmet law through SB 147. Under the current law (RSMo 302.026), riders under 26 must wear a helmet at all times. Riders 26 and older may ride without a helmet only if they carry liability insurance, carry health insurance that covers motorcycle injuries, and have completed a MoDOT-approved motorcycle safety course and held a motorcycle license for at least two years. All passengers must wear helmets regardless of age.

Since the helmet law change, Missouri motorcycle fatalities have increased 47% statewide. In 2023, 175 motorcyclists died — the deadliest year on record. Fifty-eight of the 138 fatalities in 2024 involved riders not wearing a helmet or wearing a non-DOT-compliant helmet.

Here is the critical legal point: if you were legally riding without a helmet and suffered a head injury, the insurance company may argue that your head injury would have been less severe had you worn a helmet. Under Missouri's comparative negligence rule, this could reduce your recovery. An experienced motorcycle accident attorney can counter this argument — but it highlights why documenting your compliance with the exemption requirements is important.

Talk to a motorcycle accident attorney

Motorcycle accident claims require an attorney who understands the unique challenges riders face: anti-motorcycle bias from adjusters and juries, helmet law arguments, lane-positioning disputes, and the tendency for drivers to claim they "never saw" the motorcycle.

A St. Louis motorcycle accident attorney will evaluate your case under Missouri's pure comparative negligence standard, counter bias-driven arguments about rider fault, gather evidence that the other driver violated your right of way, handle all communication with insurance companies, and negotiate a settlement that reflects the full severity of your injuries — which are almost always more serious than car accident injuries.

Initial consultations are free, and most attorneys work on contingency — you pay nothing unless they win your case. Given the bias motorcyclists face and the severity of motorcycle injuries, professional representation is not optional — it's essential.

Dangerous roads for motorcyclists in St. Louis

St. Louis's interstate convergence — I-70, I-64, I-44, and I-55 — creates challenging riding conditions with heavy traffic, aggressive merging, and limited sight lines through construction zones. Grand Boulevard and Kingshighway Boulevard are the top crash corridors in the city for all vehicles, and motorcyclists are especially vulnerable on these high-volume streets. The Poplar Street Bridge, where three interstates converge to cross the Mississippi River, is a chronic bottleneck where distracted drivers pose a serious threat to lane-filtering motorcyclists. The I-70/I-270 interchange in north St. Louis County sees frequent rear-end collisions at merge points. Surface streets like Gravois Avenue, Jefferson Avenue, and Chippewa Street see high crash volumes. St. Louis averages roughly 25 traffic collisions per day citywide. Motorcyclists should exercise particular caution on these corridors during rush hours and in wet conditions.

Missouri's motorcycle laws

Missouri's helmet law (RSMo 302.026, amended by SB 147 in 2020) requires helmets for riders under 26 at all times. Riders 26 and older may ride without a helmet if they carry liability insurance, carry health insurance covering motorcycle injuries, and have completed a MoDOT-approved safety course and held a motorcycle license for at least 2 years. All passengers must wear helmets regardless of age. Lane splitting is not explicitly legal or illegal in Missouri — it exists in a gray area, and officers can cite riders for unsafe operation. If you crash while lane splitting, it can be used as evidence of fault. Missouri requires motorcycle insurance minimums of 25/50/10: $25,000 per person bodily injury, $50,000 per accident bodily injury, and $10,000 property damage. Uninsured motorist coverage is mandatory on all Missouri auto policies at $25,000/$50,000 and cannot be waived.

Anti-motorcycle bias and protecting your claim

Motorcyclists face a well-documented bias in insurance claims and jury trials. Insurance adjusters frequently assume motorcyclists were riding recklessly, speeding, or weaving through traffic — regardless of the actual facts. Drivers who caused the crash often claim they "didn't see" the motorcycle, shifting blame onto the rider's visibility rather than their own inattention. Under Missouri's pure comparative negligence system, every percentage of fault attributed to you directly reduces your recovery. To protect yourself: wear high-visibility gear and a DOT-compliant helmet (even if you legally qualify for the exemption), ride with a dashcam or helmet camera if possible, document your compliance with the helmet exemption requirements (carry proof of insurance, health coverage, safety course completion, and license tenure), and consult an attorney who specifically handles motorcycle accident claims — not just general personal injury. An attorney who understands rider dynamics can counter bias-driven arguments effectively.

Motorcycle Accident FAQ — St. Louis & Missouri

Missouri has a five-year statute of limitations for most personal injury claims under Mo. Rev. Stat. § 516.120. For wrongful death claims, the deadline is three years from the date of death under Mo. Rev. Stat. § 537.100. While five years sounds generous, evidence fades and witnesses relocate. Starting early gives your attorney more leverage. If a government entity is involved, a 90-day notice may be required.

Under RSMo 302.026, as amended by SB 147 in 2020, riders under 26 must wear a DOT-compliant helmet at all times. Riders 26 and older may ride without a helmet if they meet three conditions: they carry liability insurance, they carry health insurance that covers motorcycle injuries, and they have completed a MoDOT-approved motorcycle safety course and held a motorcycle license for at least two years. All passengers must wear helmets regardless of age. Since the law changed, motorcycle fatalities have increased 47% statewide.

Yes. If you were legally riding without a helmet and suffered a head injury, the insurance company may argue that your head injury would have been less severe had you worn a helmet. Under Missouri's pure comparative negligence rule, this argument could reduce your recovery. An experienced motorcycle accident attorney can counter this by showing the head injury was caused by impact forces that a helmet would not have prevented, or by challenging the medical basis of the insurer's argument.

This is one of the most common defenses in motorcycle accident cases. Drivers frequently claim they "didn't see" the motorcycle. Under Missouri law, drivers have a duty to look and yield. Failure to see a motorcycle that was lawfully present in a traffic lane is not a defense — it's evidence of inattention or negligence. Your attorney can use physical evidence, witness testimony, traffic camera footage, and accident reconstruction to demonstrate that you were visible and the driver simply failed to look.

Lane splitting is neither explicitly legal nor illegal in Missouri. It exists in a legal gray area. Officers can cite motorcyclists for unsafe operation if they believe the lane splitting was dangerous. More importantly for your claim: if you were lane splitting at the time of the crash, the insurance company will almost certainly argue that lane splitting contributed to the accident and use it to increase your percentage of fault. This would reduce your recovery under Missouri's comparative negligence rule.

Motorcycle accident injuries are typically more severe than car accident injuries, and compensation reflects this. You may be entitled to current and future medical expenses (surgery, rehabilitation, prosthetics), lost wages and reduced earning capacity, pain and suffering, emotional distress, property damage (motorcycle, riding gear), and loss of enjoyment of life. Missouri does not cap non-economic damages in most personal injury cases. Your recovery is reduced by your percentage of fault under Missouri's pure comparative negligence rule.

Under Mo. Rev. Stat. § 537.765, your compensation is reduced by your percentage of fault but never completely barred — even if you are found 99% at fault. This is one of the most plaintiff-friendly fault rules in the country. However, insurance adjusters will aggressively try to maximize the fault attributed to you, especially as a motorcyclist. Common tactics include blaming your speed, lane position, visibility, or helmet non-use. An experienced attorney counters these arguments.

Most motorcycle accident attorneys in St. Louis work on a contingency fee basis — you pay nothing upfront and nothing unless they win your case. The typical contingency fee is 33% before trial or 40% if the case goes to trial. The initial consultation is free. Given the anti-motorcycle bias in insurance claims, professional representation is essential to protect your rights.

Missouri requires minimum auto insurance of 25/50/25, which is often insufficient for serious motorcycle injuries. If the at-fault driver's coverage isn't enough, you can file an underinsured motorist (UIM) claim through your own policy. Missouri mandates UM/UIM coverage of $25,000/$50,000 on every auto policy — it cannot be waived. You may also have purchased higher UIM limits. An attorney can help you stack all available coverage to maximize your recovery.

Yes. St. Louis City is an independent city with its own court system (22nd Judicial Circuit), police department (SLMPD), and jurisdiction. St. Louis County is entirely separate, with the 21st Judicial Circuit and the St. Louis County Police Department. Your case must be filed in the correct jurisdiction based on where the crash occurred. Many motorcycle accidents happen on interstates that cross the city-county boundary. Your attorney will determine the correct jurisdiction.
