Federal Trucking Regulations Federal Trucking Regulations

Commercial truck accidents are rarely “ordinary” crashes. Because tractor-trailers and other large commercial vehicles operate across state lines and pose greater risks on the road, they are governed by strict federal and state safety rules.  Learn more about federal trucking regulations.

When a serious truck crash happens in San Diego, those federal trucking regulations often play a central role in determining who is liable and how strong your injury claim may be.

Understanding how these rules work can make a major difference in the outcome of your case. Here is what you need to know and how Jassim Law can help protect your rights.

What are federal trucking regulations?

Most commercial trucks are regulated by the Federal Motor Carrier Safety Administration (FMCSA), a division of the U.S. Department of Transportation. The FMCSA establishes nationwide safety standards and regulations that apply to interstate trucking companies and drivers. Even when a crash occurs locally in San Diego, these federal rules may still apply if the truck was engaged in interstate commerce.

These regulations are designed to reduce accidents by addressing key safety risks such as fatigue, poor maintenance, overloaded cargo, and inadequate driver training.

When a trucking company or driver violates these regulations and that violation contributes to a crash it can significantly strengthen an injury victim’s liability claim.

Key federal regulations that impact liability

Several FMCSA rules frequently become central issues in San Diego truck accident cases:

  1. Hours-of-Service (HOS) Rules

Driver fatigue is a leading cause of truck crashes. To reduce exhaustion-related accidents, federal hours-of-service rules limit how long a commercial driver can operate without rest. These regulations restrict:

  • Daily driving hours
  • Weekly driving limits
  • Required rest breaks
  • Mandatory off-duty periods

Drivers must record their time using electronic logging devices (ELDs).

If a driver exceeded legal driving limits or falsified log records, and fatigue contributed to the crash, that violation can be powerful evidence of negligence. In some cases, it may also indicate that the trucking company pressured the driver to ignore safety rules.

  1. Maintenance and Inspection Requirements

Federal regulations require trucking companies to:

  • Regularly inspect their vehicles
  • Maintain detailed maintenance records
  • Repair safety defects promptly
  • Conduct pre-trip and post-trip inspections

Brake failures, tire blowouts, steering malfunctions, and lighting issues can all lead to catastrophic crashes. If a company failed to properly maintain its fleet, that failure may create direct liability for the crash—separate from any fault of the driver.

  1. Driver Qualification Standards

Commercial drivers must meet strict qualification standards, including:

  • Proper commercial driver’s license (CDL)
  • Medical certification
  • Background and driving record review
  • Ongoing training requirements

If a trucking company hires or retains a driver with a history of serious violations, substance abuse, or disqualifying medical conditions, the company itself may be liable for negligent hiring or supervision – even punitive damages.

  1. Drug and Alcohol Testing

FMCSA regulations mandate drug and alcohol testing for commercial drivers:

  • Pre-employment testing
  • Random testing
  • Post-accident testing
  • Reasonable suspicion testing

If a driver was under the influence at the time of a crash—or if the company failed to conduct required testing—that violation can dramatically impact liability and the damages you may be entitled to recover.

  1. Cargo Securement Rules

Improperly loaded or unsecured cargo can shift during transit, causing rollovers, jackknifes, or debris spills. Federal cargo securement regulations specify how freight must be loaded and secured.

Liability in these cases may extend beyond the driver to include the trucking company, a freight broker, or a third-party loading company.

How federal violations affect a San Diego truck crash claim

In California personal injury cases, liability is typically based on negligence—whether someone failed to use reasonable care. However, when a truck driver or company violates a federal safety regulation, that violation can serve as strong evidence that they failed to meet their legal duty.

In some cases, it may even support a theory of negligence per se, meaning the violation of a safety law designed to prevent the type of harm that occurred helps establish fault.

Federal violations can also:

  • Increase settlement leverage
  • Strengthen your position in negotiations
  • Support claims against multiple parties
  • Justify higher compensation in severe injury cases

Because truck accident injuries are often catastrophic—spinal cord injuries, traumatic brain injuries, fractures, or wrongful death—the stakes are extremely high.

Multiple parties may be liable

Unlike ordinary car accidents, truck crash cases often involve multiple potentially liable parties, including:

  • The truck driver
  • The trucking company (employer)
  • The trailer owner
  • A maintenance contractor
  • A cargo loading company
  • A manufacturer (if a defective part caused failure)

Federal regulations frequently define responsibilities among these parties. Identifying who violated which regulation is a critical step in building a strong case.

Why early investigation matters

Trucking companies and their insurers often deploy rapid response teams immediately after a serious crash. Their goal is to protect the company’s financial interests.

Important evidence may include:

  • Electronic logging device data
  • Black box (event data recorder) information
  • Driver qualification files
  • Maintenance and inspection records
  • Drug and alcohol test results
  • Internal communications

Some of this information can be lost, overwritten, or difficult to obtain without prompt legal action.
