Every year, commercial truck crashes leave Missouri families dealing with serious injuries, mounting medical bills, and unanswered questions. When a fully loaded 18-wheeler strikes a passenger vehicle, the consequences range from catastrophic injuries to wrongful death.
Understanding the causes of truck accidents can help you recognize why these collisions happen and what rights you may have. At Goldblatt + Singer, we can help you navigate every step of your claim, from the initial investigation through the resolution.
No two truck accidents are identical, but the same underlying causes of truck accidents appear repeatedly across Missouri roads. They fall into three broad categories: driver error, carrier negligence, and equipment or cargo failures.
Common causes can include:
Driver fatigue remains a persistent problem among commercial drivers. When drivers push past legal limits to meet delivery deadlines, reaction times slow and judgment suffers, putting everyone on the road at risk.
At highway speeds, taking your eyes off the road for even a few seconds can cause a driver to miss a slowing vehicle, a sudden lane shift, or a road hazard entirely. Texting, adjusting a GPS, or reaching for items in the cab are all it takes to turn a routine trip into a serious crash.
Large commercial trucks require far greater stopping distances than passenger vehicles. Driving too fast for road conditions increases the likelihood of a crash and the severity of the impact.
Drug and alcohol use are strictly prohibited for commercial drivers, but impairment continues to appear in serious crashes. When a driver operates an 80,000-pound vehicle under the influence, the consequences can be catastrophic, and liability often extends beyond the driver to the carrier that put them on the road.
Trucking companies are legally obligated to keep their fleets in a safe condition. Worn brakes, faulty lighting, and defective tires are maintenance failures that can cause or worsen a crash, and ignoring documented problems creates substantial liability.
Unsecured or overweight cargo can shift during transport, causing a truck to jackknife or lose control on a curve. Violations by shippers or loading crews are a recognized factor in rollover and multi-vehicle crashes.
Commercial trucks have four significant blind spots where nearby vehicles disappear from view. According to the FMCSA, drivers should check their mirrors every 8 to 10 seconds to stay aware of vehicles entering those zones. Failing to do so before lane changes or wide turns regularly results in sideswipe collisions.
A blown tire on an 80,000-pound truck can cause the driver to lose control instantly. Carriers that skip routine tire inspections or run worn tires past their service life put every vehicle in the surrounding area at serious risk.
Trucking companies that place unqualified or undertrained drivers behind the wheel create liability that extends beyond the driver. Failure to verify licensing, driving history, or conduct proper training is an independent ground for a negligence claim against the carrier.

Missouri roads carry heavy commercial truck traffic year-round, and the crash data reflects the human cost. According to FMCSA Crash Statistics for Missouri, Missouri has already recorded 789 vehicles involved in fatal and non-fatal crashes in recent months, with 8 fatalities and 320 injuries. For anyone hurt by a commercial vehicle in the St. Louis area, these figures represent real families, real medical bills, and real losses.
Truck accident cases are more legally complex than standard car accident claims because multiple parties can share responsibility. Identifying every liable party requires an investigation beyond the police report.
The driver may be personally liable for negligent operation, including speeding, distracted driving, or impaired driving. The trucking company may be liable under the doctrine of respondeat superior, which holds employers responsible for the negligent acts of employees performed within the scope of their duties. If the company pressured the driver to violate hours-of-service limits or failed to properly maintain the vehicle, those are independent grounds for liability.
A cargo loading company may be liable if unsecured freight contributed to the crash, and a manufacturer may face a product liability claim if a defective part played a role. Missouri follows a pure comparative fault standard, meaning an injured person can still recover damages even if they bear some share of fault.
All motorists sharing Missouri roads with commercial vehicles can take steps to reduce their exposure to risk. The following practices can help keep you safer near large trucks:
These habits lower risk, but cannot eliminate it. When a driver or a company acts negligently, responsibility for the resulting injuries lies with them.
