What counts as a CDL and who must have one in Illinois?

If a driver operates a heavy commercial motor vehicle in Chicago, Cook County, DuPage County, Lake County, Will County, Kane County, McHenry County, Sangamon County, or Champaign County, Illinois law and federal rules usually require a Commercial Driver’s License, known as a CDL. Federal law defines a commercial motor vehicle in part by weight, passenger capacity, or hazardous materials. Generally, a vehicle requires a CDL if it has a gross vehicle weight rating or combined weight rating of 26,001 pounds or more, carries 16 or more passengers including the driver, or transports hazardous materials requiring placards. See the federal definition in 49 CFR 383.5 and 49 CFR 390.5T and the Illinois Vehicle Code at 625 ILCS 5/6-500 et seq. You can confirm federal CDL basics in 49 CFR Part 383 and Illinois CDL provisions at 625 ILCS 5/6-500 to 6-526.

Illinois also adopts many federal safety rules for both interstate and intrastate carriers. The Illinois Administrative Code incorporates parts of the Federal Motor Carrier Safety Regulations. See 92 Ill. Adm. Code 390.1020 adopting federal Parts 382, 385, 387, 390, 391, 392, 393, 395, and 396. The Illinois codified text is available at ilga.gov.

Which FMCSA rules commonly appear in Illinois truck crash cases?

In civil cases arising from crashes on I-90, I-94, I-55, I-80, and other corridors across Chicago, Aurora, Naperville, Joliet, Rockford, Springfield, Peoria, Elgin, Waukegan, Bloomington, and Champaign-Urbana, these federal rules frequently matter:

• CDL standards and disqualifications under 49 CFR Part 383.
• Controlled substances and alcohol testing under 49 CFR Part 382, including post-accident testing requirements at 49 CFR 382.303.
• Driver qualifications and medical certification under 49 CFR Part 391, including driver qualification files at 49 CFR 391.51 and medical standards at 49 CFR 391.41.
• Driving rules under 49 CFR Part 392, including prohibitions on texting and handheld mobile phones at 49 CFR 392.80 and 392.82.
• Vehicle parts and accessories under 49 CFR Part 393, such as brakes, lights, tires, and cargo securement rules.
• Hours of Service and electronic logs under 49 CFR Part 395, including the 11-hour, 14-hour, and 60/70-hour limits and Electronic Logging Devices.
• Inspection, repair, and maintenance under 49 CFR Part 396, including daily inspection reports and annual inspections.
• Accident registers and recordkeeping under 49 CFR 390.15.
• Financial responsibility minimums under 49 CFR Part 387.

Illinois specifically incorporates these rules for many carriers operating within state lines, so violations can be relevant even in intrastate crashes. See 92 Ill. Adm. Code 390.1020.

How can CDL or FMCSA violations help prove negligence in Illinois?

In civil court, you prove negligence by showing a duty, a breach of that duty, causation, and damages. Federal safety regulations and the Illinois Vehicle Code help establish the duty and can be persuasive proof of a breach. For example:

• Unqualified driver: If a motor carrier put a driver on the road without the correct CDL class or endorsements required by 49 CFR Part 383 and 625 ILCS 5/6-500 et seq., that may support negligent hiring or negligent entrustment claims.
• HOS violations: If logs show driving more than 11 hours or beyond the 14-hour window under 49 CFR 395.3, the driver may have been fatigued, and the company may have inadequate supervision practices.
• Distracted driving: Using a hand-held mobile phone while operating a CMV violates 49 CFR 392.82 and Illinois’ handheld ban, 625 ILCS 5/12-610.2, suggesting a breach of duty.
• Maintenance lapses: Worn brakes or bald tires can violate 49 CFR Part 393 and Part 396; company maintenance records then become central to proving breach and causation.

Courts weigh whether the violation was designed to protect against the type of harm suffered. Illinois decisions treat many statutory or regulatory violations as strong evidence of negligence when the safety rule aims to protect the class of persons and the type of harm at issue. See discussion of Illinois negligence per se below.

What is negligence per se in Illinois and how does it apply to truck cases?

Illinois does not apply a strict negligence per se doctrine that automatically imposes liability for any statute violation. Instead, violating a statute or ordinance designed to protect human life or property is treated as prima facie evidence of negligence when the violation proximately causes the injury. The jury still evaluates all the evidence.

Key Illinois cases explain the approach:

• Kalata v. Anheuser-Busch, Inc. The Illinois Supreme Court stated that a statutory violation is prima facie evidence of negligence. See 144 Ill. 2d 425 (1991).
• Abbasi v. Paraskevoulakos The court reaffirmed that a safety ordinance violation is evidence of negligence, not automatic liability, and the plaintiff must show proximate cause. See 187 Ill. 2d 386 (1999).

In truck cases, violations of FMCSA rules adopted in Illinois by 92 Ill. Adm. Code 390.1020 can function similarly to statute or ordinance violations when those rules exist to prevent the very harm that occurred. For instance, if a crash involves a fatigued driver and the driver broke the Hours of Service rules, a jury may consider that violation as evidence of negligence when assessing fault.

How do Hours of Service and ELD data show fatigue or logbook falsification?

Hours of Service limits aim to reduce fatigue-related crashes. For most property-carrying CMV drivers:

• 11-hour driving limit within a 14-hour window after coming on duty, with required off-duty time. See 49 CFR 395.3.
• 60/70-hour limit in 7 or 8 consecutive days, respectively, depending on the carrier’s schedule.
• Electronic Logging Devices required for most drivers to record duty status. See 49 CFR 395.8 and ELD requirements at 49 CFR 395 Subpart B.

Key proof often includes:

• ELD raw data and event history showing driving, on-duty, sleeper berth, and edits.
• Telematics and GPS pings from the tractor, trailer, or dispatch systems that corroborate movement.
• Fuel receipts, toll records, weigh station entries, and bills of lading, which can expose logbook falsification.

Fatigue is a recognized safety risk. National crash data show the size of the problem: in 2021, large trucks were involved in 5,700 fatal crashes nationwide, a 17 percent increase from 2020, according to the Federal Motor Carrier Safety Administration’s Pocket Guide to Large Truck and Bus Statistics. See FMCSA Pocket Guide 2023 via fmcsa.dot.gov.

What evidence should be preserved immediately after a truck crash in Illinois?

Time-sensitive evidence can determine liability in collisions throughout the Chicago Loop, Near West Side, South Side, or along I-90, I-94, I-55, and I-80. Consider quickly preserving:

• Driver qualification file as required by 49 CFR 391.51, including application, prior employer checks, motor vehicle records, road test, and medical certificate.
• Drug and alcohol testing records under 49 CFR Part 382, including any post-accident tests required by 49 CFR 382.303.
• HOS and ELD data under 49 CFR Part 395, including ELD output files, back-office audit trails, and any edits or annotations.
• Vehicle inspection and maintenance files under 49 CFR Part 396, such as driver vehicle inspection reports, periodic inspections, and repair orders.
• Accident register and reports under 49 CFR 390.15.
• ECM and module data including engine control module, braking and stability control events, and airbag control module data if available.
• Cargo and shipper documents including bills of lading, weight tickets, and load securement instructions under 49 CFR 393.100 to 393.136.
• Company policies and training materials on HOS, distracted driving, route planning, and safety supervision.

Illinois law recognizes claims for negligent spoliation in limited circumstances when there is a duty to preserve evidence, such as through a special relationship, contract, statute, or a clear undertaking to preserve. See Boyd v. Travelers Ins. Co., 166 Ill. 2d 188 (1995).

What is a spoliation letter and why send it quickly?

A spoliation letter is a written notice asking the motor carrier, driver, broker, shipper, or maintenance vendor to preserve specific evidence. Prompt notice helps establish a duty to preserve and reduces the risk of data loss from routine overwriting of ELD logs, telematics, and ECM data. Under Illinois law, once a party has reason to know litigation is likely, destroying relevant evidence can lead to sanctions or a separate negligent spoliation claim depending on the relationship and facts. See Boyd.

A thorough preservation notice often lists the regulatory records discussed above and requests that electronic data be imaged in forensically sound formats. It is especially important in serious crashes in Cook County, Will County, and along the I-55 and I-80 freight corridors where fleets may rotate equipment quickly.

Who can be liable: driver, motor carrier, broker, shipper, or maintenance shop?

Liability in Illinois may extend beyond the individual driver depending on the facts:

• Driver: Negligent driving, speeding, distraction, fatigue, or rule violations can create personal liability.
• Motor carrier: Vicarious liability under respondeat superior if the driver was acting within the scope of employment; additional direct liability for negligent hiring, training, retention, supervision, or maintenance practices.
• Broker: Liability theories against brokers are fact-specific. Some courts have limited claims due to federal preemption under the Federal Aviation Administration Authorization Act, but negligence claims may still be argued depending on the role played and control exercised. Analysis turns on the broker’s conduct and control of safety.
• Shipper or loader: If improper loading or securement caused a shift or spill and the shipper or a third-party loader controlled cargo securement contrary to 49 CFR Part 393 Subpart I, they may share responsibility.
• Maintenance shop or manufacturer: Faulty repairs or defective components can lead to negligent repair or product liability claims.

How do negligent hiring, training, or retention claims work in Illinois?

Illinois recognizes claims for negligent hiring, negligent retention, and negligent supervision when an employer knew or should have known the employee was unfit and that unfitness caused the injury. See, for example, Illinois cases discussing these duties, including Van Horne v. Muller, 185 Ill. 2d 299 (1998) and Hills v. Bridgeview Little League Ass’n, 195 Ill. 2d 210 (2000).

In the trucking context, the driver qualification file is crucial. Under 49 CFR 391.51, carriers must maintain records of the driver’s application, prior employment checks, motor vehicle records, road tests or CDL equivalency, and medical certification. Red flags can include a history of HOS violations, prior crashes, failed or missed drug tests under 49 CFR Part 382, or repeated maintenance citations. If a carrier ignored these warnings or failed to conduct the required checks, that supports negligent hiring or retention theories.

What vehicle maintenance and inspection rules matter in court?

FMCSA rules require systematic inspection, repair, and maintenance programs. See 49 CFR 396.3. Daily driver vehicle inspection reports, annual inspections, and repair records help prove whether the fleet kept equipment safe. Common issues include:

• Brake performance: Violations of 49 CFR 393.40 to 393.55 can cause longer stopping distances.
• Tires and wheels: 49 CFR 393.75 prohibits operating with exposed ply or belt material or tread separation.
• Lighting and conspicuity: Reflective tape and lamps under 49 CFR 393 Subpart B are critical at night or in bad weather on I-90 or I-55.
• Cargo securement: 49 CFR 393.100 to 393.136 sets out securement and tiedown rules, often central in tip-overs and load shift cases.

Maintenance documentation is discoverable under 49 CFR 396.3 and related sections. In Chicago and surrounding counties, courts may also consider whether a carrier’s internal policies met or fell below industry practice in addition to the minimum federal rules.

How does drug and alcohol testing affect liability?

After certain crashes, federal rules require post-accident alcohol and controlled substances testing. See 49 CFR 382.303. The carrier must maintain drug and alcohol testing records, including test results and chain-of-custody documentation, according to 49 CFR 382.401. Failure to test when required or failure to remove a driver from service after a positive test can support negligence claims against the carrier. Additionally, Illinois adopts Part 382 for many intrastate carriers via 92 Ill. Adm. Code 390.1020, making these records relevant in local cases.

What if the trucker was using a handheld phone in Chicago or on I-90?

Federal rules prohibit a CMV driver from using a hand-held mobile telephone while driving, including reaching, holding, or dialing in a way that requires pressing more than a single button. See 49 CFR 392.82. Illinois law separately bans handheld device use while driving with limited exceptions. See 625 ILCS 5/12-610.2. Evidence can include ELD or telematics timestamps, call logs, carrier cell phone policies, and nearby camera footage in the Chicago Loop, Near West Side, South Side, or along suburban corridors in DuPage and Lake Counties. Violations can be persuasive evidence of negligence when linked to the crash.

What defenses do trucking companies raise and how are they countered?

Common defenses in Illinois truck cases include:

• Independent contractor: A carrier may argue the driver was an independent contractor. Courts look at control and federal leasing regulations, and Illinois law may still allow vicarious liability depending on the facts.
• Compliance defense: The company may claim full compliance with FMCSRs. Plaintiffs can counter with evidence of systemic issues not obvious in check-the-box paperwork, such as unrealistic dispatch schedules that encourage HOS violations.
• Comparative fault: Defendants may argue the plaintiff was partly at fault. Detailed crash reconstruction, ECM data, and scene evidence help address fault allocation.
• Superseding cause: The defense may suggest an intervening event broke the causal chain. Careful timeline analysis of ELD, GPS, and witness accounts can rebut this.

How is fault allocated under Illinois comparative negligence?

Illinois uses modified comparative negligence. If you are more than 50 percent at fault, you cannot recover; if you are 50 percent or less at fault, your recovery is reduced by your percentage of fault. See 735 ILCS 5/2-1116. This makes early collection of objective data, such as ECM and ELD outputs and traffic camera footage, especially important in Cook County, Will County, and throughout the I-55 and I-80 corridors.

What damages may be available in civil Illinois truck cases?

Available damages depend on the facts and claims, which may include:

• Medical expenses and rehabilitation.
• Lost wages and reduced earning capacity.
• Pain, suffering, and loss of normal life.
• Property damage to your vehicle and contents.
• Wrongful death damages under 740 ILCS 180 for eligible survivors.

In appropriate Illinois cases, punitive damages may be available when conduct is willful and wanton, subject to statutory limits and case law. See 735 ILCS 5/2-1115.05. Courts assess these claims carefully, and they are not awarded in every case. Your legal team weighs whether evidence of egregious rule violations supports such a claim.

What deadlines apply to Illinois truck crash lawsuits?

Deadlines are strict:

• Personal injury: Generally, 2 years from the date of injury. See 735 ILCS 5/13-202.
• Wrongful death: Generall,y 2 years. See 740 ILCS 180/2(d).
• Claims against local public entities: Often 1 year under the Local Governmental and Governmental Employees Tort Immunity Act. See 745 ILCS 10/8-101.

Because ELD and telematics data can be overwritten and carriers rotate equipment, acting quickly helps preserve vital evidence.

What special issues arise in crashes on I-55, I-80, or in Cook County?

Illinois is a major freight hub. Heavily traveled corridors include I-90 and I-94 through the Chicago Loop and Near West Side, I-55 to Joliet, I-80 across Will County, I-57 on the South Side, and I-294 around O’Hare and the western suburbs. High truck volumes increase the presence of interstate carriers subject to federal rules. Local considerations include:

• Municipal restrictions: Chicago regulates truck routes and certain boulevard restrictions through the Chicago Municipal Code. Violations can be relevant if routing contributed to the collision.
• Construction zones: Frequent work zones require heightened attention to lane closures and reduced speed limits. FMCSR 392.2 requires compliance with local traffic laws.
• Weather and lake-effect conditions: Sudden visibility or traction issues on I-90, I-94, and I-55 can intersect with cargo securement and safe speed duties.

How do we gather black box ECM and telematics data?

Modern tractors store engine and event data in the Engine Control Module, sometimes including speed, throttle, brake application, and last-stop records. Fleets also use telematics platforms that store GPS, hard-braking, and stability control events. Steps often include:

• Immediate preservation notice listing ECM, ELD, and third-party telematics sources.
• Forensic imaging by a qualified download technician to preserve original data.
• Cross-checking ECM with ELD and dispatch records to verify timing and movement.

While federal rules do not mandate recovery of ECM data, they do require ELD records and various safety files. See 49 CFR Parts 395, 391, and 396. Accident register requirements appear at 49 CFR 390.15. These materials, together with Illinois discovery rules, often form the backbone of a reconstruction in cases venued in Cook County and neighboring circuits.

How do insurance and federal financial responsibility rules play in?

Most interstate motor carriers must maintain minimum levels of financial responsibility to pay for harm caused by their operations:

• General freight: At least $750,000 in public liability. See 49 CFR 387.9.
• Hazardous materials: Higher minimums, often $5,000,000, depending on the cargo. See 49 CFR 387.9.

Illinois intrastate carriers have additional requirements through state regulations. Insurance issues can be complex when multiple policies exist for the motor carrier, the trailer owner, a broker, or a shipper. Early identification of all potentially applicable policies is important, especially in multi-vehicle crashes on I-80 and I-55.

What steps should you take after a truck crash in Illinois?

After a collision, your first priority is safety and medical care. From a civil case perspective, consider:

• Call 911 and cooperate with law enforcement. Police reports and scene photos help reconstruct events.
• Document everything, including vehicle positions, skid marks, cargo spills, placards, and any visible smartphone use by the trucker.
• Preserve your vehicle until it can be inspected. Do not authorize disposal without guidance.
• Avoid recorded statements to an opposing insurer before you have counsel.
• Consult with an Illinois truck accident lawyer who understands FMCSA records, ELD data, and Illinois evidence rules. These cases are complex and involve multiple entities.

National and state data show the stakes. Large trucks are involved in thousands of fatal crashes nationally each year, and Illinois sees a steady share due to high freight volumes and interstate corridors. See FMCSA’s Pocket Guide and Illinois Department of Transportation crash facts at idot.illinois.gov.
