Your Truck Accident Settlement Could Depend on Missouri’s Critical 90-Day Rule

If you’ve been injured in a truck accident in Missouri, there’s a powerful legal tool that could determine whether you receive fair compensation or face a lengthy court battle. Missouri’s 90-day settlement rule, codified in RSMo §537.058, creates a structured process for making time-limited settlement demands that insurance companies must take seriously. This law gives injury victims leverage by establishing specific requirements that, when followed correctly, can lead to faster settlements. The statute was enacted in 2017 as tort reform to provide insurers a statutorily mandated 90-day period to review and investigate time-limited demands (rather than allowing plaintiffs to use artificially short deadlines to set up bad faith claims); a properly prepared, compliant time-limited demand can still be used as evidence in later extracontractual (bad faith) litigation, so demands prepared correctly continue to affect settlement leverage.

Many accident victims don’t realize that Missouri law provides this strategic advantage, especially in truck accident cases where insurance policies often carry higher limits and injuries tend to be more severe. The statute creates a framework that protects both injured parties and insurers by setting clear expectations for settlement negotiations. Understanding how to properly use this tool can make the difference between a fair settlement and leaving money on the table.

💡 Pro Tip: Start documenting your injuries and losses immediately after a truck accident, as you’ll need comprehensive information to make an effective time-limited demand under Missouri law.

Understanding Your Rights Under Missouri’s Time-Limited Demand Statute

Missouri’s time-limited demand statute provides specific protections for truck accident victims when dealing with insurance companies. The law requires that any written settlement demand must remain open for acceptance for at least 90 days from when the liability insurer receives it. This mandatory waiting period was enacted in 2017 as tort reform to protect insurers from plaintiffs’ attorneys who were using artificially short time-limit demands to set up potential bad faith claims, by giving insurers a statutorily mandated 90-day period to review and investigate claims. Truck accident lawyers in St. Louis understand how critical this protection is, especially when dealing with commercial trucking companies and their insurers who often have teams of adjusters and attorneys working to minimize payouts.

The statute applies to all personal injury, bodily injury, and wrongful death claims, making it particularly relevant for truck accident cases where injuries are often catastrophic. To be valid under the law, your demand must include specific elements: the monetary amount requested or a request for policy limits, the date and location of the accident, descriptions of all known injuries, identification of parties to be released, and an offer of unconditional release under Missouri law. Working with experienced truck accident lawyers in St. Louis ensures these technical requirements are met precisely, as even minor errors can invalidate your demand.

Perhaps most importantly, the law establishes evidentiary rules that affect bad faith litigation. A demand that complies with §537.058 must remain open for at least 90 days; conversely, a demand that does not comply with the statute shall not be admissible as evidence in any lawsuit alleging extracontractual damages (amounts exceeding policy limits). The statute itself does not automatically create extracontractual liability for refusing to settle within 90 days — liability for extracontractual or bad faith damages arises under separate common-law or statutory claims — but a properly prepared demand can be used as evidence in such claims, which encourages insurers to carefully consider reasonable offers.

💡 Pro Tip: Always send your time-limited demand via certified mail with return receipt requested – this creates indisputable proof of when the 90-day clock starts ticking.

The Step-by-Step Process for Making a Valid 90-Day Settlement Demand

Successfully using Missouri’s 90-day settlement rule requires careful attention to procedural requirements and timing. The process begins with gathering comprehensive documentation about your truck accident, injuries, and damages. Unlike typical settlement negotiations, a time-limited demand under §537.058 must follow a specific format and include mandatory information to be legally effective. Understanding each step helps ensure your demand carries the full weight of Missouri law.

  • Document all injuries and obtain complete medical records from every healthcare provider who has treated you since the accident
  • Calculate your total damages, including medical expenses, lost wages, and pain and suffering – or specifically request the insurance policy limits
  • Prepare HIPAA-compliant authorization forms for each healthcare provider, allowing the insurer to verify your medical treatment and injuries
  • Draft a written demand that explicitly references Missouri statute §537.058 and includes all required elements
  • Include authorization forms for your employers if you’re claiming lost wages, with specific details about your work history and income
  • Send the complete demand package via certified mail, return receipt requested, to establish proof of delivery
  • Mark your calendar for 90 days from the delivery date – the insurer must respond within this timeframe or risk evidentiary consequences in later extracontractual litigation

💡 Pro Tip: Create a detailed injury diary starting immediately after your accident – insurers often dispute the severity of injuries, and contemporaneous notes carry significant weight in negotiations.

How Experienced Truck Accident Lawyers in St. Louis Navigate Settlement Demands

Making an effective time-limited demand requires more than just following procedural rules – it demands strategic thinking about valuation, timing, and negotiation leverage. Truck accident lawyers in St. Louis who regularly handle these cases understand how to maximize the statute’s benefits while avoiding common pitfalls that could invalidate your demand. The Missouri RSMo 537.058 time-limited settlement demands process becomes particularly powerful when combined with thorough investigation and compelling presentation of your damages.

Halvorsen Klote Davis brings extensive experience in handling truck accident cases throughout Missouri, including deep knowledge of how insurance companies respond to time-limited demands. Their attorneys understand that timing is crucial – making a demand too early might undervalue your claim if injuries haven’t fully manifested, while waiting too long could push you dangerously close to the statute of limitations. They also recognize that the 90-day rule doesn’t apply within 90 days of trial, making strategic timing essential for maintaining maximum leverage throughout your case.

The resolution process often involves complex calculations and negotiations. Insurers receiving compliant demands must carefully evaluate their exposure, knowing that rejecting a reasonable offer could affect later bad faith claims because a properly prepared demand may be admissible as evidence. Experienced attorneys know how to present demands that create this pressure while remaining reasonable enough to withstand scrutiny if the case proceeds to trial. They also understand local factors unique to St. Louis truck accident cases, such as common trucking routes through the city and typical jury verdicts in similar cases.

💡 Pro Tip: Consider the insurer’s perspective when setting your demand amount – unreasonably high demands may actually reduce your leverage by making it easier for insurers to justify rejection.

Critical Documentation Requirements That Can Make or Break Your Demand

The success of a time-limited demand often hinges on the quality and completeness of supporting documentation. Missouri law specifically requires that demands be accompanied by lists of healthcare providers and HIPAA-compliant authorizations, plus employer information and authorizations if claiming wage loss. These aren’t mere suggestions – they’re mandatory elements that, if missing or improperly formatted, can render your entire demand invalid and inadmissible in any future bad faith lawsuit against the insurer.

Medical Documentation and HIPAA Compliance

Healthcare documentation presents unique challenges in truck accident cases because injuries often involve multiple providers – emergency rooms, surgeons, physical therapists, and specialists. Each provider must be listed with complete contact information, and you must provide HIPAA-compliant written authorizations that specifically allow the liability insurer to obtain your records. St. Louis truck accident attorneys understand that generic medical release forms often don’t meet statutory requirements, potentially invalidating otherwise strong demands. The FMCSA Crash Causal Factors Program data shows that heavy-duty truck crashes often result in complex injury patterns requiring treatment from multiple specialists, making comprehensive medical documentation even more critical.

💡 Pro Tip: Create a master list of every healthcare provider from day one, including ambulance services and diagnostic facilities – missing even one provider could give insurers grounds to reject your demand.

Strategic Considerations for Truck Accident Cases Under the 90-Day Rule

Truck accident cases present unique strategic opportunities and challenges when using Missouri’s time-limited demand statute. Commercial trucking policies typically carry much higher limits than standard auto insurance, often $1 million or more, which changes the dynamics of settlement negotiations. Additionally, trucking companies and their insurers are sophisticated defendants who understand the implications of extracontractual exposure, making proper demand preparation crucial for success.

Leveraging Commercial Policy Limits and Multiple Defendants

Unlike typical car accidents, truck crashes often involve multiple potentially liable parties – the driver, trucking company, cargo loader, and maintenance provider. Missouri truck accident lawyers must carefully consider which parties to include in the demand and how to structure releases to maximize recovery while preserving claims against other defendants. The statute’s requirement to identify "parties to be released" becomes particularly complex when dealing with corporate structures and multiple insurance policies. Understanding how the 90-day rule interacts with commercial trucking regulations and insurance requirements can significantly impact your settlement strategy.

💡 Pro Tip: Request policy limits rather than a specific amount if you suspect your damages exceed coverage – this prevents undervaluing your claim while maintaining maximum pressure on the insurer.

Frequently Asked Questions

Common Concerns About Missouri’s 90-Day Settlement Rule

Understanding how Missouri’s time-limited demand statute works raises many questions for truck accident victims. These frequently asked questions address the most common concerns about using this powerful legal tool effectively.

💡 Pro Tip: Write down all your questions before meeting with an attorney – the 90-day rule has many technical requirements that are easy to overlook without legal guidance.

Next Steps After Making Your Time-Limited Demand

Once you’ve submitted a compliant demand, the waiting period begins. Understanding what happens during these 90 days and how to prepare for various outcomes helps you stay ready for whatever response the insurer provides.

💡 Pro Tip: Continue treating for your injuries and documenting new symptoms during the 90-day period – this information may be crucial if settlement negotiations extend beyond the initial demand.

1. What happens if the insurance company doesn’t respond within 90 days to my truck accident settlement demand?

If an insurer fails to accept a compliant time-limited demand within the 90-day period, the statute does not by itself create extracontractual liability. Instead, §537.058 provides that a demand that fails to comply with the statute shall not be admissible as evidence in any lawsuit alleging extracontractual damages, while a compliant demand may be used as evidence in later bad faith litigation. Liability for extracontractual damages arises from separate bad faith claims, but the evidentiary effect of a compliant demand can be used as leverage by plaintiffs’ attorneys in continued negotiations or at trial.

2. Can I make a time-limited demand if I’m still treating for injuries from my truck accident?

Yes, you can make a demand while still treating, but timing is crucial. The statute requires you to describe "all known injuries," so you must be honest about ongoing treatment while reserving rights for unknown future complications. St. Louis truck accident attorneys often recommend waiting until you reach maximum medical improvement or have a clear prognosis, but sometimes earlier demands make strategic sense, especially when approaching statutory deadlines.

3. Does Missouri’s 90-day rule apply to all truck accident cases?

The rule applies to personal injury, bodily injury, and wrongful death claims against any tort-feasor’s liability insurer, which includes most truck accident cases. However, it doesn’t apply to demands made within 90 days of trial once a lawsuit is filed. Additionally, the statute only creates leverage in cases where the insurer has settlement authority – some commercial policies require trucking company consent for settlements.

4. What makes a time-limited demand "non-compliant" under Missouri law?

Common compliance failures include missing required elements (amount, injury descriptions, parties to be released), failing to send by certified mail, not including proper medical or employment authorizations, or not explicitly referencing §537.058. Even small technical errors can invalidate your demand. Non-compliant demands cannot be used as evidence of bad faith in extracontractual damages lawsuits, eliminating your leverage.

5. How do truck accident lawyers in St. Louis determine the right settlement amount to demand?

Experienced attorneys analyze multiple factors including medical expenses, lost wages, future treatment needs, pain and suffering, and local jury verdict trends. For truck accidents, they also consider the severity typical of commercial vehicle crashes and higher policy limits. Missouri truck accident lawyers may request specific amounts based on careful calculation or simply demand policy limits when damages clearly exceed coverage.

Work with a Trusted Truck Accident Lawyer

Missouri’s 90-day settlement rule provides powerful protection for truck accident victims, but only when used correctly. The technical requirements for valid time-limited demands leave no room for error – missing deadlines, omitting required information, or failing to follow precise formatting requirements can eliminate your leverage entirely. Given that truck accidents often result in catastrophic injuries with life-changing consequences, ensuring your demand complies with every aspect of §537.058 becomes crucial for securing fair compensation. The complexity increases when dealing with commercial trucking companies and their sophisticated insurance carriers who understand exactly how to challenge non-compliant demands.

When it comes to handling truck accident settlements in Missouri, navigating the ins and outs of the 90-day rule is essential for a fair resolution.
