Large commercial trucks have four significant blind spots, directly in front of the cab, directly behind the trailer, and along both sides. When a truck driver fails to check these zones before changing lanes or turning, the results can be catastrophic for anyone in that space.
Common Injuries and Damages in a Blind Spot Truck Accident
The force of an 80,000-pound truck striking a passenger vehicle from the side is devastating. Common damages include:
- Side-impact and structural damage to vehicles
- Broken mirrors on both the truck and surrounding cars
- Damage to guardrails, bridges, and road medians
Beyond property damage, victims frequently suffer life-altering injuries. A sudden side impact can cause traumatic brain injuries, severe neck and spinal injuries from the violent whipping motion, and internal injuries that aren’t immediately visible. These injuries often require months or years of ongoing medical treatment costs that your claim should fully account for.

Jackknife Accidents, When a Truck Becomes a 70-Foot Barrier
A jackknife occurs when a truck’s cab and trailer fold inward at the hitch point, swinging the trailer violently across lanes. These accidents are among the most dangerous on Missouri highways and in most cases, they are preventable.
Truck drivers are required to adjust their speed for road conditions, particularly when moisture or ice reduces traction. A driver who fails to slow down on a wet I-70 or icy I-64 isn’t just making a mistake, they’re breaching their duty of care.
The rare exception is a truly unforeseeable jackknife. In practice, these are uncommon. Most jackknife accidents trace back to one of two causes: driver error or equipment failure, both of which create legal liability.
Regular mechanical checks, particularly monitoring defective tires and wheels, are one of the most effective ways to prevent jackknifing. When a trucking company skips these checks and a crash results, that failure is evidence of negligence.
Overloaded and Overweight Trucks – A Hidden Danger on Missouri Roads
Federal and Missouri law set strict limits on how much a commercial truck can weigh and for good reason. An overloaded truck takes longer to stop, is harder to control in emergencies, and puts enormous stress on tires and brakes that can lead to sudden failures.
Under Missouri and federal regulations, a truck is considered overweight if its gross vehicle weight exceeds 80,000 pounds. Additional axle limits apply:
- Interstate system: No more than 20,000 pounds per axle
- Missouri highways: No more than 22,000 pounds per axle
- Commercial zones (per Section 304.190): No more than 22,400 pounds per axle
The manufacturer’s weight rating for the steering axle and tires must also never be exceeded, a detail trucking companies sometimes ignore under pressure to move freight faster.
The Scale of the Problem
Each year, over 208 million trucks pass through weigh stations across the U.S. Despite strict enforcement, tens of thousands are found to be operating over the legal weight limit. An overweight truck doesn’t just endanger other drivers, it accelerates the destruction of Missouri’s roads and bridges, creating secondary hazards for everyone.
Missouri Statute Section 304.200 does allow permits for non-divisible oversized loads, but those permits come with strict movement restrictions, including a prohibition on travel during major holidays such as Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas.
If an overloaded truck caused your crash, that weight violation is powerful evidence of negligence. Mutrux Firm Injury Lawyers knows how to obtain weigh records, inspection logs, and cargo manifests to prove it.
