Indiana Truck Accident Laws: Deadlines, Fault Rules & Your Rights

Indiana truck accident laws give injured people two years to file a personal injury lawsuit and use a "modified comparative fault" rule that cuts off compensation if a person is more than half at fault. Truck crash claims in Indiana also pull in federal trucking regulations that don't apply to ordinary car accidents, which can change who is held responsible and how much insurance is available to pay a claim. Understanding these rules early can make the difference between a fair settlement and a denied claim.

Key takeaways

• Indiana's statute of limitations for most truck accident injury claims is 2 years from the date of the crash.
• Indiana follows a modified comparative fault rule with a 51% bar — you cannot recover damages if you're found more than 50% at fault.
• Federal FMCSA rules on hours of service, inspections, and driver qualifications often apply on top of Indiana law.
• Multiple parties besides the driver — including the trucking company, loader, or maintenance shop — may share liability.
• Electronic logs, black box data, and maintenance records can disappear quickly, so early preservation requests matter.

Indiana's Filing Deadline for Truck Accident Claims

Under Indiana truck accident laws, a person injured in a truck crash generally has two years from the date of the collision to file a personal injury lawsuit. This deadline comes from Indiana's general personal injury statute of limitations and applies to most truck accident claims. If a family member died in the crash, Indiana's wrongful death statute also generally requires filing within two years of the death.

Missing this deadline typically means losing the right to sue entirely, regardless of how strong the case is. Because truck crash investigations take time — especially when multiple companies and insurers are involved — it's wise to start gathering evidence and speaking with a licensed Indiana attorney well before the two-year mark, not at the last minute.

Exceptions That Can Change the Clock

Certain situations, such as claims involving a minor or claims against a government entity, can shorten or otherwise affect filing timelines under Indiana law. Anyone unsure which deadline applies to their situation should confirm the details with a licensed Indiana attorney rather than relying on the general two-year rule alone.

How Indiana's 51% Fault Bar Works

Indiana uses a modified comparative fault system with a 51% bar. This means an injured person can recover compensation as long as they are found to be 50% or less at fault for the crash. If a jury or insurance adjuster decides the injured person is 51% or more at fault, they recover nothing.

When a person is partially at fault but under the 51% threshold, their compensation is reduced by their percentage of fault. Here's a simple example:

• A car driver is rear-ended by a semi-truck that was following too closely.
• Total damages (medical bills, lost wages, pain and suffering) are calculated at $200,000.
• An insurance adjuster or jury decides the car driver was 20% at fault for braking suddenly without signaling, and the truck driver was 80% at fault for following too closely.
• The car driver's recovery is reduced by 20%, leaving $160,000 instead of $200,000.

Now compare that to a scenario where the car driver is found 55% at fault — perhaps for an unsafe lane change in front of the truck. Under Indiana's 51% bar, that driver would recover nothing, even though the truck driver was still partly responsible.

Because trucking companies and their insurers often try to shift blame onto the injured person to push fault above 50%, how fault gets argued and proven is often the central battle in these claims.

Federal Trucking Rules Apply Alongside Indiana Law

Large commercial trucks operating across state lines are regulated by the Federal Motor Carrier Safety Administration (FMCSA), and these rules work alongside — not instead of — Indiana state law. Violations of federal rules can be strong evidence of negligence in an Indiana truck accident case.

Key federal rules that often come up include:

• Hours-of-service limits restricting how long a driver can be on duty and behind the wheel before taking required rest breaks.
• Driver qualification requirements, including valid commercial driver's licenses, medical certifications, and background checks.
• Vehicle inspection and maintenance standards for brakes, tires, lights, and other safety-critical systems.
• Drug and alcohol testing requirements for commercial drivers.

Federal law also sets a minimum liability insurance requirement for interstate motor carriers — generally $750,000 for most general freight carriers, with higher minimums (commonly $5 million) for carriers hauling certain hazardous materials. This is a regulatory floor, not a cap, and many carriers carry significantly more coverage. Readers can review the federal regulations directly through the FMCSA's regulations page.

Who Can Be Held Responsible After an Indiana Truck Crash

Truck accident cases often involve more defendants than a typical car accident claim. Depending on the facts, responsibility may extend to:

• The truck driver, for things like speeding, fatigue, distraction, or unsafe maneuvers.
• The motor carrier (trucking company), for negligent hiring, inadequate training, pressuring drivers to violate hours-of-service rules, or poor vehicle maintenance.
• Shippers or loaders, if improperly loaded or secured cargo caused the truck to become unstable or shift.
• Maintenance or repair companies, if faulty repairs or skipped inspections contributed to a mechanical failure like brake or tire failure.
• Truck or parts manufacturers, if a defective part — such as brakes, tires, or coupling systems — contributed to the crash.
• Freight brokers, in some cases, if they negligently selected an unsafe or unqualified carrier.

Specific crash types often point toward specific causes and defendants. For example, wide turn crashes and blind spot collisions frequently involve driver error, while rollover crashes often raise questions about cargo loading, speed, or vehicle maintenance.

Where Truck Traffic Is Heaviest in Indiana

Indiana's location makes it a major crossroads for freight traffic, which also means a higher concentration of large trucks on certain routes. Corridors that typically see heavy commercial truck traffic include:

• I-65, connecting Chicago-area traffic through Indianapolis down toward Louisville.
• I-70, running east-west through Indianapolis and linking to Ohio and Illinois.
• I-80/I-94, crossing northern Indiana near Gary and the Chicago metro area, a major corridor for cross-country freight.
• I-69, serving as a growing freight route connecting Indianapolis toward Fort Wayne and the Michigan border.

The Indianapolis area in particular functions as a major logistics and distribution hub, which brings significant truck volume to its surrounding interstates and interchanges.

Evidence That Matters in Truck Accident Cases

Truck crash cases depend heavily on specialized evidence that isn't present in typical car accident claims — and much of it can be lost, overwritten, or legally destroyed if not requested quickly. Important evidence includes:

• Electronic logging device (ELD) and paper logbook data, showing whether the driver violated hours-of-service limits.
• Event data recorder ("black box") data, which can show speed, braking, and steering inputs in the moments before the crash.
• Maintenance and inspection records, revealing whether known mechanical issues were ignored or repairs were improperly done.
• The driver qualification file, including licensing, training, drug testing history, and prior safety violations.
• Dashcam or trailer camera footage, if the truck or nearby vehicles were equipped with cameras.

Many trucking companies have data retention policies that allow them to delete or overwrite this information after a set period. A prompt written request — often called a spoliation or evidence preservation letter — can legally obligate the company to preserve it. Waiting even a few weeks can mean this evidence is gone for good.

What to Do After a Truck Accident in Indiana

1. Call 911 and get medical attention, even if injuries seem minor at first — some injuries show up hours or days later.
2. Document the scene with photos and video of vehicle positions, damage, skid marks, road conditions, and the truck's company name and DOT number.
3. Get the truck driver's information, including their license, the carrier's name, and insurance details, if it's safe to do so.
4. Identify witnesses and get their contact information before they leave the scene.
5. Request the police crash report once it's available, and keep a copy for your records.
6. Avoid giving recorded statements to the trucking company's insurer before speaking with a licensed attorney.
7. Keep records of medical treatment, lost wages, and property damage as they accumulate.
8. Send or have an attorney send an evidence preservation letter to the trucking company as soon as possible.

Compensation Available in Indiana Truck Accident Claims

People injured in truck accidents in Indiana may be entitled to recover compensation for:

• Medical expenses, both past and future
• Lost wages and reduced future earning capacity
• Pain and suffering
• Permanent disability or disfigurement
• Property damage to the vehicle and personal belongings
• Wrongful death damages for surviving family members, in fatal crash cases

The specific types and amounts of compensation available depend heavily on the facts of each case, the severity of injuries, and how fault is apportioned under Indiana's 51% bar rule.

Finding and Evaluating a Licensed Indiana Truck Accident Lawyer

Truck accident claims are more complex than typical car accident cases because of the number of parties involved, the role of federal regulations, and the higher insurance policies at stake. When looking for a licensed Indiana attorney to evaluate a potential claim, consider:

• Experience specifically with trucking cases, not just general car accident claims, since federal regulations and commercial insurance policies require specialized knowledge.
• A track record of handling cases involving motor carriers, including negotiating with commercial trucking insurers.
• Access to accident reconstruction and trucking industry experts, who are often needed to interpret ELD data, black box data, and maintenance records.
• Clear communication about fees
• Good standing with the Indiana State Bar, which can typically be confirmed through the state bar's attorney lookup tool.

Most attorneys who handle truck accident cases offer an initial case review before any fees are charged, which can help an injured person understand their options without financial risk up front.
