Unfortunately a moment of negligence or a missed regulation check can lead to catastrophic truck collisions. And determining what causes these accidents isn’t just important for road safety, it’s critical for injured victims who need to prove liability and pursue justice. Though truck accidents make up a small percentage of total vehicle crashes nationwide, they cause a disproportionate number of severe injuries and fatalities, typically resulting in complex legal disputes involving multiple parties.
At Christie Farrell Lee & Bell, our Indianapolis personal injury lawyers have been representing the injured across Indianapolis for over four decades. Below, we break down the most common causes of truck accidents in Indianapolis and throughout Indiana, supported by state crash data and our own legal experience representing victims of these high-impact collisions.
Speeding: A Leading Risk Factor in Truck Collisions
According to Indiana’s 2022 crash data, large trucks account for 5% of all speeding-related crashes statewide, but their impact is far more severe. Speed-related truck accidents result in 103.5 injuries per 1,000 occupants – more than double the rate of non-speeding accidents at 43.7 per 1,000.
This increased danger stems from the unique challenges trucks face at high speeds. Their substantial weight requires longer stopping distances, while their size limits maneuverability. Even exceeding the speed limit by just 10 miles significantly increases the risk of dangerous accidents like rollovers, rear-end collisions, and jackknife crashes.
Driver Fatigue and Federal Hours of Service Violations
Truck driver fatigue is one of the most underreported but dangerous contributors to truck accidents in Indianapolis. While the state doesn’t break out fatigue as a separate cause, national research — including from the FMCSA shows that driver exhaustion plays a role in a significant number of serious truck crashes, especially those occurring on high-traffic corridors.
Indiana truckers are subject to strict federal hours of service regulations, which limit how long a commercial driver can be behind the wheel without a break. When these rules are ignored or falsified, liability shifts to both the driver and often the trucking company.
We’ve built cases where fatigue was hidden in manipulated paperwork, and we’ve held companies accountable for incentivizing speed over safety.
Neglected Maintenance and Mechanical Failure
Not every truck crash is caused by reckless driving. In many of our cases, we’ve seen catastrophic accidents that stemmed from a blown tire, failed brakes, or a detached trailer — all pointing to inadequate fleet maintenance. Even though human error dominates crash reports, mechanical failures remain a significant underlying factor.
According to our analysis of trucking company liability, companies are legally obligated to perform routine inspections and keep maintenance records. When they don’t, they expose everyone on the road to avoidable danger.
Weather-Related Truck Accidents in Indiana
Inclement weather complicates everything for large trucks. Snow, fog, sleet, and rain drastically affect braking ability and visibility. And when an 80,000-pound vehicle starts to slide, there’s no regaining control easily.
Indianapolis highways like I-65, I-70, and I-69 are particularly prone to these conditions. But bad weather doesn’t automatically absolve a driver or company of responsibility. In fact, failure to reduce speed, use proper equipment, or delay delivery can all contribute to liability in a weather-related crash.
In these weather-based accident cases, evidence such as DOT advisories, weather logs, and trucking dispatch records show whether a driver had sufficient information to make safer decisions.
Improper Lane Changes and Blind Spot Negligence
One of the most frequent causes of truck accidents we see in Indianapolis involves unsafe lane changes or failures to check blind spots. Large commercial vehicles have four major blind zones — front, rear, and both sides — and if a driver isn’t properly trained or fails to signal before merging, smaller vehicles can get sideswiped or forced off the road.
These claims often involve proving that a trucker didn’t maintain proper lookout, wasn’t trained adequately, or was operating under time pressure that led to rushed, reckless lane changes. When trucking companies fail to reinforce defensive driving practices, we make that failure part of the case.
Injuries That Commonly Result From Indianapolis Truck Crashes
Truck accidents frequently result in severe, life-altering injuries due to the massive size and force involved in these collisions. Even at relatively low speeds, the impact of an 80,000-pound vehicle can cause devastating trauma and has a significantly higher fatality rate. Here are the most common types of injuries in truck accidents:
- Traumatic brain injuries – ranging from mild concussions to severe trauma causing permanent cognitive disabilities, memory loss, and personality changes
- Spinal cord trauma – including herniated discs, nerve damage, and catastrophic injuries leading to paraplegia or quadriplegia
- Complex fractures – particularly to legs, hips, and ribs, often requiring surgical intervention and extended physical therapy
- Internal injuries – severe damage to organs from the extreme force of impact, which may cause life-threatening complications
- Fatal injuries – sadly, many truck accidents result in death due to the severity of trauma sustained
Your settlement from a truck accident should comprehensively cover all aspects of your injuries and damages. This includes not only immediate medical expenses but also long-term care needs, lost wages, diminished earning capacity, and compensation for pain and suffering. A thorough settlement should account for both current and future medical treatments, rehabilitation costs, necessary medical equipment, and any modifications needed for your home or vehicle to accommodate new physical limitations.
