Not every crash with a large vehicle is treated like a regular car accident, especially in Missouri. If your accident involves a commercial vehicle, different laws and regulations apply. These rules can affect who is at fault and how much compensation you can pursue.
Federal law (49 CFR § 390.5) defines a commercial motor vehicle (CMV) as any vehicle used in interstate commerce that meets one or more of these criteria:
- It has a gross weight or combined weight of 10,001 pounds or more.
- It is designed to transport eight or more passengers (including the driver) for payment.
- It is designed to transport 15 or more passengers (including the driver) without payment.
- It carries hazardous materials requiring special placards under federal law.
Missouri-Specific Rules
Missouri law (RSMo § 302.700) follows these federal standards but applies them to many vehicles used only in Missouri. This includes vehicles used for:
- Intrastate goods transportation
- Construction work
- Public transportation
- Commercial delivery services
If your accident involved a business vehicle—like a local delivery van or construction truck—different safety rules and liability standards may apply.
Standard Vehicles in Commercial Crashes
We often handle cases involving the following types of vehicles:
- 18-wheelers, semi-trucks, and tractor-trailers
- Delivery vans (Amazon, FedEx, UPS, DHL)
- Construction vehicles (dump trucks, cement mixers, cranes)
- Public buses and charter buses
- Utility and maintenance trucks
- Fleet vehicles and commercially registered pickups
- Hazardous material transport trucks
Why This Matters for Your Claim
Accidents involving commercial vehicles can impact your case in several ways:
- Higher insurance coverage: Commercial vehicles often carry policies starting at $750,000, with many exceeding $1 million.
- Strict safety rules: Federal and Missouri laws regulate commercial vehicle safety; violations can prove negligence.
- Corporate liability: You may be able to hold the driver and the trucking company, employer, or contractor responsible.
Determining if the vehicle in your crash qualifies as a commercial vehicle is one of the first steps in building your case. This impacts the evidence we gather, the laws we apply, and the compensation you may recover.
Unfortunately, some drivers falsify their logbooks under pressure from employers. Dispatchers often push drivers to violate HOS rules, which puts everyone on the road at risk. When investigating these crashes, we frequently find proof of HOS violations—evidence that helps establish negligence under federal and Missouri law.
Distracted and Impaired Driving
Distracted driving is hazardous when large commercial vehicles are involved. Dispatch devices, cell phones, and GPS systems often divert drivers’ attention. Federal law prohibits texting while driving a commercial vehicle (49 CFR § 392.80), but violations remain common.
In addition to distraction, impaired driving is another serious issue. The law sets a strict 0.04% blood alcohol concentration (BAC) limit for commercial drivers. Alcohol, drugs, and even certain prescription medications can lead to impairment. When drivers or carriers violate these laws, they face severe liability.
Improper Loading and Cargo Securement
Federal rules require trucking companies to properly load and secure cargo (49 CFR Part 393, Subpart I). Improperly loaded cargo can cause:
- Rollovers
- Jackknifing
- Cargo spills on Missouri roads
- Failure of brakes or steering systems
We often see crashes caused by unsecured or shifting cargo. We hold the trucking company and any third-party loading contractors responsible in these cases.
Vehicle Maintenance Failures
The law requires trucking companies to inspect and maintain their vehicles regularly. Inspections must cover critical components like:
- Brakes
- Tires
- Steering systems
- Lights and reflectors
- Coupling devices
Skipping inspections or ignoring known defects puts lives at risk. We often find falsified maintenance logs or evidence of incomplete repairs during our investigations. These details play a critical role in proving fault.
Negligent Hiring and Poor Training
Trucking companies must follow federal driver qualification rules (49 CFR Part 391). They must:
- Verify that drivers are medically qualified
- Confirm drivers hold valid commercial licenses (CDLs)
- Conduct background checks
- Provide proper training on operating commercial vehicles
Some companies ignore these obligations to save time or money, especially today’s truck driver shortage. Hiring unqualified drivers or failing to provide proper training often leads to preventable accidents. When this happens, we hold employers fully accountable for their negligence.
How a Commercial Vehicle Accident Lawyer Can Help
At Buchanan, Williams & O’Brien, we believe in a proactive, comprehensive approach to commercial vehicle cases. General personal injury experience does not always address the specialized regulations, corporate defenses, and significant insurance policies. We focus on:
- Thorough Investigations: We gather driver logs, vehicle black box data, truck maintenance records, and expert reconstructions to prove exactly how the crash occurred.
- Identifying All Liable Parties: The driver may not be the only liable party. We look at the trucking company, manufacturers, and loading crews for potential negligence. This ensures you seek compensation from all available sources.
- Strong Insurance Negotiations: Commercial insurance carriers often carry million-dollar policies and aggressively resist paying claims. We fight for a fair settlement on your behalf.
- Trial-Ready Cases: While many claims are settled outside of court, we prepare every case for litigation to demonstrate our readiness. This approach strengthens your position during settlement talks.
- Comparative Fault Issues: Missouri observes comparative fault laws that could reduce compensation if you share blame for the accident. We work diligently to refute unfair blame and ensure the focus remains on the commercial entity’s negligence.
