Underride Truck Accident Attorney in Indianapolis

Truck accidents are some of the most horrifying events that can happen on the road. Underride truck accidents in particular often result in devastating injuries that can cause overwhelming medical bills, lost wages, and a decrease in the victim’s quality of life.

Underride collisions occur when a passenger vehicle slides under the trailer of a semi truck or other large commercial vehicle. Underride truck accidents are far more complex than typical car accidents. Not only are the injuries often more severe, but the legal issues surrounding liability, regulations, and compensation are more difficult to navigate.

Trucking companies are heavily insured and backed by their own team of truck accident lawyers trained to minimize payouts from truck accidents. Without an experienced truck accident attorney on your side, you risk being outmatched and under-compensated.

At Crossen Law Firm, we’ve seen firsthand how the insurance company, the trucking companies, and the truck drivers themselves try to shift blame. The accident victim must know how to push back. We’ve helped semi-truck accident victims recover full compensation for medical expenses, lost wages, severe injuries, pain and suffering, and future care needs for their truck accident claim. After all, these are traumatic injuries. The most effective truck accident attorneys stand up with you.

If you or someone you love has been involved in an underride truck accident, you need more than medical care—you need the most qualified underride truck accident lawyer. Contact our truck accident lawyers today at 317-401-8626.

Three Types of Underride Accidents

Underride truck accidents typically fall into one of three categories: rear, side, or front. Each presents unique dangers and occurs under different driving conditions—but all involve a smaller vehicle, typically a passenger vehicle, becoming trapped under a much larger one.

Rear Underride Accidents

These are the most common form of underride crashes. Such an accident occurs when a car crashes into the back or side of a semi truck or commercial trailer and the smaller vehicle slides underneath it.

Underride guards are steel barriers installed on the back—and in some cases, the sides—of trailers and trucks. Despite the high clearance of large trucks and commercial trucks you see on the road today, in these truck accidents the top of the car is crushed or torn off entirely.

Serious accidents involving the rear underside usually happen when:

• A truck driver stops suddenly or is parked on the shoulder
• Brake lights or reflectors are dim, broken, or missing
• The trailer’s guard is rusted, bent, or detached
• Weather conditions reduce visibility or stopping time
• A negligent driver fails to check blind spots

Side Underride Accidents

These crashes occur when a vehicle slides under the side of a truck, often during turns, lane changes, or intersections. These accidents tend to be even more deadly, as most commercial trucks do not have federally required side guards—despite years of advocacy from safety experts.

Side underride collisions typically occur when:

• A truck makes a wide turn and blocks a lane
• A car attempts to pass and misjudges the space
• Visibility is reduced due to fog, rain, or nighttime driving
• A truck driver merges unexpectedly into another lane

Front Underride Accidents

These accidents happen when a large truck or semi drives over the rear of a smaller vehicle. These typically occur in chain-reaction crashes, when a truck is following too closely or fails to brake in time. Due to their larger size and momentum, semi trucks can easily drive over smaller vehicles, causing the smaller vehicle to become lodged underneath the semi truck.

These accidents often result in:

• Roof and trunk collapse of the passenger vehicle
• Rear-seat passenger deaths
• Total vehicle destruction

Each of these underride crash types shares a common thread: a dangerous mismatch in size, weight, and protection. The smaller vehicle is at an enormous disadvantage, and often experiences the majority of damage resulting in severe injuries for its occupants that may even prove fatal.

Strong legal advocacy in the form of an underride truck accident lawyer is crucial if you’ve experienced an underride truck accident. The attorneys at Crossen Law Firm are well versed in dealing with these scenarios. We have many years of experience assessing underride truck accidents, often employing accident reconstruction experts so we can get to the bottom of what happened in your case.

How Truck Equipment Failures Can Cause an Underride Accident

Semi trucks are mechanical giants that require constant upkeep. Even small failures—like a broken taillight or worn-out brake pad—can have deadly consequences, especially when they result in an underride crash.

Many underride accidents in Indianapolis stem from issues like:

• Malfunctioning or non-existent underride guards
• Faulty brakes or suspension systems
• Burned-out brake lights or signal indicators
• Broken reflective tape or visibility marking
• Trailer height exceeding regulated clearance

These aren’t minor oversights—they’re critical safety failures. The Federal Motor Carrier Safety Administration (FMCSA) mandates regular inspections for all commercial trucks. But some companies cut corners to save time or costs, creating trucks with serious mechanical issues. These trucks pose a danger to other drivers on the road, most of them more vulnerable due to their smaller vehicle size.

If you have an underride crash case involving a large truck, Crossen Law Firm will carefully examine:

• Vehicle inspection reports
• Maintenance logs
• Repair invoices
• Crash scene photographs
• FMCSA safety audits

If any evidence points to failed maintenance or falsified logs, we hold trucking companies and maintenance contractors accountable for negligence.

Improperly Loaded Cargo

Cargo issues may not be the first thing you think of after a truck crash, but in many underride accidents, poorly loaded freight by liable parties is a hidden contributor.

Improper cargo loading can:

• Unbalance the trailer and affect steering
• Shift during turns or stops, destabilizing the truck
• Increase the braking distance beyond safe margins
• Put strain on the trailer structure and guard
• Block rear or side lights, reducing visibility

Who’s responsible should a truck accident occur from improper cargo loading? Often it’s a third-party logistics provider, warehouse crew, or loading dock worker—not the driver. But if the load isn’t balanced, secured, or documented correctly, it’s a disaster waiting to happen.

It’s important that your truck accident lawyer reviews:

• Loading manifests (paperwork)
• Photographs of the trailer interior
• Cargo securement logs
• Witness testimony from the driver and loaders

Holding everyone accountable—from truck drivers to freight handlers—is how we build strong truck accident claims for our clients.

Preventing Accidents With Underride Guards

Rear underride guards are required by federal law, but many trailers on the road don’t meet the minimum safety standards—or evade inspections altogether.

A properly designed and maintained underride guard can prevent death and reduce severe injuries suffered by the accident victim. But unfortunately, not every truck accident claim features underride guards.

Types of Underride Guards:

Rear Guards: Required by federal law for most trailers since 1998, but many are outdated, weak, or misaligned.

Side Guards: Not yet required by federal law in the U.S., but widely used in other countries to protect against side underride.

Front Guards: Rare and mostly seen in safety research; very few trucks have any front underride protection.

Problem: Rear guards are only effective if they are low enough, wide enough, and strong enough. A trailer riding too high, or a guard that’s rusted or bent, can completely fail in a crash.

At Crossen Law Firm, we assess:

• Whether guards met or violated federal height and strength standards
• Inspection records showing guard damage or wear
• Whether the trailer was modified or repaired improperly
• Whether a stronger or modernized guard would have made a difference

The trucking industry has long resisted requirements for stronger guards, often citing cost. But we believe safety should never be optional—especially when lives are at stake.

Not all semi trucks or other commercial vehicles are equipped with these guards. When accidents occur, spinal cord injuries, traumatic brain injuries, and fatal injuries can result in even low-velocity accidents.

Doesn’t a truck accident victim who suffered simply due to the absence of these guards deserve fair compensation? Yes. That’s why the Crossen legal team fights for your right to seek compensation from all liable parties after a collision with a large commercial vehicle, especially if you’ve sustained catastrophic injuries.

Injuries That Could Be Fatal After an Underride Truck Accident

Underride accidents are among the most violent on the road because of where they impact the vehicle. The point of contact is often at or above the windshield—directly into the head and chest area of the car’s occupants. The chances of severe personal injury cases are high. Even low-speed underride crashes can produce traumatic or fatal injuries.

Common injuries include:

• Traumatic Brain Injuries (TBIs) – from blunt trauma or skull penetration
• Spinal Cord Damage – leading to paralysis or permanent mobility issues
• Crushed Limbs and Amputations – especially when the dashboard collapses
• Internal Organ Damage – often from blunt force trauma to the chest or abdomen
• Severe Facial Injuries – requiring reconstructive surgery
• Burns – if the car catches fire after impact

Who May Share Liability With the Truck or Passenger Vehicle Driver

In an underride truck accident case, fault doesn’t fall on just one party. In fact, these cases often involve multiple layers of liability—especially when corporate negligence, faulty equipment, or regulatory violations are at play.

The most common parties who may share responsibility:

The Truck Driver: Drivers can be held liable for speeding, distracted driving, failing to use hazard lights, or violating hours-of-service laws (e.g., driving while fatigued).

The Trucking Company: A trucking company can be liable for negligent hiring, which includes failing to properly vet potential drivers, failing to inspect or maintain vehicles, pressuring drivers to meet unrealistic deadlines, causing them to violate hours of service laws, or ignoring federal and state safety laws.

The Cargo Loader or Third-Party Freight Handler: Improperly loaded cargo in commercial trucks can destabilize a trailer, reduce braking capacity, or cause lights/guards to be blocked. If cargo played a role, the loading company may be at fault for any commercial truck accidents that occur.

Maintenance Contractors: If maintenance was outsourced and their faulty or negligent maintenance contributed to the crash—like worn brakes or a damaged underride guards—the maintenance provider could be responsible.

Manufacturers: If a defective underride guard, lighting system, or trailer part caused or worsened the crash, the manufacturer could be liable under product liability law.

Government Entities: In rare cases, local or state governments could share fault if poor road design or conditions, lack of signage, or hazardous construction zones played a role.

As experienced Indianapolis truck accident attorneys, Crossen Law works to uncover every potentially responsible party in your truck accident case—and our legal team pursues each of them to ensure our clients receive full compensation for their truck accident claim, that may include lost wages, under Indiana law.

Truck Evidence That May Help Determine Fault

In an underride truck accident case, evidence is everything. Without it, trucking companies and insurance companies may deny liability or blame the victim. That’s why securing documentation and data quickly after a truck accident is critical to the success of your case.

We aggressively pursue the following types of evidence:

• Black Box Data (Event Data Recorder) – Captures truck driver speed, brake usage, acceleration, and more in the seconds before the crash
• Electronic Logging Devices (ELD) – Shows how long the driver had been on duty, potentially exposing violations of driving limits
• Driver Logs & Inspection Reports – Required by law, these can show mechanical issues or rest violations after commercial truck accidents
• Maintenance and Repair Records – Proves whether failed components were ever flagged or fixed
• Police Reports – Includes initial crash assessment, road conditions, citations, and witness info
• Dash Cam or Traffic Camera Footage – Can visually demonstrate how the semi truck accident occurred
• Crash Scene Photos and Measurements – Help our reconstruction experts analyze impact points and forces.
• Witness Testimony – Provides firsthand accounts of what occurred.

In a recent truck accident case, a commercial vehicle’s black box revealed it was traveling above the speed limit. Our truck accident lawyers subsequently discovered the driver never attempted to brake before the crash. This single piece of data changed the entire outcome of the legal claim.

As your underride truck accident attorney, Crossen Law acts quickly to send preservation letters (also called “spoliation letters”) to ensure evidence is not destroyed or altered after the crash. Our goal as semi truck accident lawyers is to build an irrefutable case on your behalf.

Wrongful Death Damages After an Underride Truck Accident

An underride semi truck crash can be especially severe. The chances of fatal truck accidents are higher. If your truck accident happened anywhere in central Indiana, you need experienced Indianapolis truck accident attorneys who know how to negotiate with insurance companies and will hold trucking companies accountable for expenses you incur after a fatal semi truck accident. Under Indiana’s Wrongful Death Statute, surviving family members may be eligible to file a claim for financial compensation.

While it’s impossible to determine the exact amount of compensation you’ll receive for a truck accident claim, several key factors are taken into account in every personal injury or wrongful death case.

Your claim may include both economic and non-economic damages. Additionally, any unique circumstances surrounding the accident can also influence the outcome of your case.

Here’s what those economic and non-economic damages might include:

• Final Medical Bills: If the deceased received any medical treatment between the time of the accident and death, those medical bills can be claimed.
• Funeral and Burial Costs: Wrongful death compensation can cover burial plots, cremation, headstones, and other end-of-life costs.
• Loss of Income: If the deceased was a wage earner, their projected future earnings—including benefits, pensions, and bonuses—may be recoverable.
• Loss of Companionship or Parental Guidance: State law allows for compensation for the emotional support, mentorship, and household contributions that are lost when a loved one dies.
• Mental Anguish: Survivors may receive damages for the emotional toll caused by a sudden, violent loss—especially in cases involving traumatic or public deaths.

Our experienced attorneys will fight for you after your semi truck accident in Indianapolis, or elsewhere in Indiana.

Underride Truck Accident FAQs

Should I Talk to the Trucking Company if They Contact Me?

Do not communicate with semi truck drivers, the truck company or the insurance company. Remember, they are building a case against you. Their truck accident attorney may contact you hoping to “collaborate” or say they are “seeking clarity on a few things.” If you cooperate, they may record your statement, twist your words, or push you into a low settlement. Always consult your attorney before speaking with them.

How Long Do I Have To File a Lawsuit?

You have two years from the date of the accident in most Indiana cases. For wrongful death claims, the two-year clock typically begins on the date of death. However, it’s best to act quickly to preserve evidence.
