The trucking industry is one of the most heavily regulated industries in the United States. The Federal Motor Carrier Safety Administration (FMCSA) sets hundreds of rules governing how trucks are operated, maintained, loaded, and who can drive them. When a trucking company or driver violates these rules and an accident results, those violations become some of the strongest evidence in your injury claim.
Understanding which federal regulations apply to your case gives you a significant advantage over victims who treat truck accidents like ordinary car crashes.
Hours of Service (HOS) Regulations
The most commonly violated and most impactful regulations in truck accident cases are the hours-of-service rules. These rules exist because fatigue is the leading cause of serious truck accidents.
Current HOS Rules for Property-Carrying Drivers
11-Hour Driving Limit. A driver may drive a maximum of 11 hours after 10 consecutive hours off duty.
14-Hour On-Duty Limit. A driver may not drive after 14 consecutive hours on duty, even if they have not used all 11 driving hours. Once the 14-hour window starts, it does not stop for off-duty time (except the sleeper berth provision).
30-Minute Break. Drivers must take at least a 30-minute break after 8 cumulative hours of driving without at least a 30-minute interruption.
60/70-Hour Limit. A driver may not drive after 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days. The clock resets after the driver takes 34 or more consecutive hours off duty (restart provision).
How HOS Violations Help Your Claim
If the truck driver who caused your accident was in violation of any HOS rule, that violation is evidence of negligence. In some cases, it constitutes negligence per se, meaning the violation alone proves the driver was negligent without needing to show that a reasonable person would have acted differently.
ELD data is the primary source for proving HOS violations. Your attorney can subpoena ELD records from the trucking company, showing exactly when the driver was driving and resting in the days leading up to the crash. If the records show the driver exceeded the 11-hour limit or skipped required breaks, liability is difficult for the defense to dispute.
If the trucking company pressured the driver to violate HOS rules to meet delivery deadlines, the company is independently liable for negligent supervision.
Electronic Logging Device (ELD) Requirements
Since December 2017, FMCSA has required most commercial motor vehicles to use certified electronic logging devices. ELDs automatically record driving time by connecting to the truck’s engine control module. They cannot be easily turned off or manipulated while the truck is in motion.
What ELD Data Shows
- Engine hours and vehicle miles driven
- Driving time vs. on-duty-not-driving time vs. off-duty time
- Date, time, and location of each duty status change
- Vehicle identification and driver identification
- Malfunctions and diagnostics
ELD Manipulation
While ELDs are harder to falsify than paper logs, drivers still find ways to cheat:
- Driving under a co-driver’s account
- Disconnecting the ELD from the engine (which triggers a malfunction indicator)
- Claiming personal conveyance (off-duty driving) while actually hauling freight
- Using unassigned driving time to hide miles
Your attorney can analyze ELD data for inconsistencies that suggest manipulation. Gaps in the data, unassigned driving events, and malfunction indicators are red flags that support your claim.
Driver Qualification Standards
FMCSA requires trucking companies to ensure every driver meets specific qualifications before putting them behind the wheel of a commercial vehicle.
Required Qualifications
- Must be at least 21 years old for interstate driving
- Must hold a valid Commercial Driver’s License (CDL) with appropriate endorsements
- Must pass a DOT physical examination every 24 months
- Must pass a road test or provide equivalent documentation
- Must have no disqualifying offenses (certain felonies, multiple traffic violations, DUI convictions)
Driver Qualification File
Trucking companies must maintain a qualification file for each driver containing:
- Application for employment
- Motor vehicle record (MVR) from every state where the driver has held a license in the past 3 years
- Road test certificate or equivalent
- Medical examiner’s certificate
- Annual review of driving record
- Drug and alcohol testing records
- Previous employer safety performance history for the past 3 years
How Qualification Violations Help Your Claim
If the trucking company hired a driver who did not meet FMCSA qualification standards, that is negligent hiring. Common violations include:
- Hiring a driver with a suspended or revoked CDL
- Failing to check the driver’s MVR before hiring
- Ignoring a history of accidents, violations, or DUI offenses
- Failing to verify previous employment safety records
- Keeping a driver on the road after a failed drug test
Negligent hiring makes the trucking company directly liable for the accident, independent of the vicarious liability that already exists for the driver’s on-the-job negligence.
Vehicle Maintenance and Inspection Requirements
FMCSA mandates a comprehensive maintenance and inspection regime for commercial trucks.
Pre-Trip Inspections
Before every trip, the driver must inspect the truck and document the results. The inspection must cover:
- Brakes, steering, lights, tires, horn, windshield wipers
- Coupling devices, wheels, rims, emergency equipment
- Any defect that could affect safe operation
If the driver found a defect and drove anyway, or if the driver skipped the pre-trip inspection entirely, that is evidence of negligence.
Periodic Inspections
Every commercial vehicle must undergo a comprehensive inspection at least once every 12 months. The inspection must be performed by a qualified inspector and documented. The inspection report must be kept on the vehicle.
Maintenance Records
Trucking companies must keep maintenance records for every vehicle showing:
- All inspections, repairs, and maintenance performed
- The nature of the defect or problem
- The corrective action taken
- The date of each action
These records show whether the trucking company maintained the vehicle properly. Missing records, gaps in maintenance, or ignored inspection findings all support a claim that the company was negligent.
How Maintenance Violations Help Your Claim
If the accident was caused by brake failure and the maintenance records show the brakes had not been inspected in 18 months, the trucking company is liable for negligent maintenance. If the pre-trip inspection report shows a tire defect that the driver noted but did not address before driving, both the driver and the company are liable.
Drug and Alcohol Testing Requirements
FMCSA has strict drug and alcohol testing requirements for commercial drivers:
Pre-employment testing. Every driver must pass a drug test before driving.
Random testing. Trucking companies must randomly test at least 50% of their drivers for drugs and 10% for alcohol annually.
Post-accident testing. After certain accidents (those involving fatalities, injuries requiring medical treatment away from the scene, or disabling vehicle damage with a citation), the driver must be tested for drugs within 32 hours and alcohol within 8 hours.
Reasonable suspicion testing. When a supervisor has reasonable cause to believe a driver is impaired.
Return-to-duty and follow-up testing. After a violation, drivers must pass testing before returning to work and face ongoing follow-up testing.
Substances Tested
The DOT drug panel tests for:
- Marijuana
- Cocaine
- Amphetamines and methamphetamine
- Opioids
- Phencyclidine (PCP)
How Drug and Alcohol Violations Help Your Claim
A positive post-accident drug or alcohol test is devastating evidence for the defense. It proves the driver was impaired at the time of the crash. Even a failed pre-employment or random test that the company ignored (allowing the driver to continue working) is evidence of negligent retention.
If the trucking company failed to conduct required random testing or allowed a driver to return to duty after a failed test without completing the required return-to-duty process, the company is directly liable.
Cargo Securement Standards
FMCSA regulations specify how different types of cargo must be loaded, distributed, and secured on commercial trucks. These regulations cover:
- Weight distribution requirements
- Tie-down and securement device specifications
- Specific rules for different cargo types (logs, metal coils, heavy machinery, intermodal containers)
- Minimum number of tie-downs based on cargo length and weight
When improperly secured cargo falls from a truck, shifts and causes a rollover, or changes the truck’s handling characteristics and contributes to a crash, the party responsible for loading is liable.
Using Federal Violations in Your Claim
Federal regulation violations strengthen your truck accident claim in several ways:
Negligence per se. Some Illinois courts treat FMCSA violations as negligence per se, meaning the violation itself proves negligence without requiring additional evidence of unreasonable behavior.
Evidence of a pattern. Violations often are not isolated. If a driver exceeded HOS limits on the day of your accident, their ELD records may show a pattern of violations over weeks or months. A pattern suggests the trucking company knew about and tolerated the violations.
Multiple liability. Violations create independent liability for the trucking company beyond vicarious liability. This matters because direct company negligence may allow for punitive damages in egregious cases.
Leverage in negotiations. Insurance companies know that FMCSA violations look terrible in front of a jury. A case with clear regulatory violations often settles for more because the defense wants to avoid trial.
Get Legal Help Immediately
Federal trucking records are not permanent. ELD data can be overwritten. Maintenance logs can be lost or destroyed. The sooner your attorney sends a preservation demand, the more evidence will be available to prove regulatory violations.
