The Rules Behind Every Big Rig on the Road
Large commercial trucks are part of daily life in and around San Jose, carrying the goods the region depends on. Because they are so large and heavy, and because their drivers spend long hours on the road, trucks are subject to regulations from the Federal Motor Carrier Safety Administration (FMCSA) that ordinary drivers never deal with.
Those rules exist to prevent exactly the kind of crash that injured you. When a driver or trucking company ignores them, the violation can become key evidence that they were negligent. Federal trucking laws cover:
How long a driver can operate a truck before a mandatory break
Who is licensed to drive a commercial truck
The driver's physical health
Alcohol limits stricter than those for other drivers
Inspections before every trip
How much insurance a trucking company must carry
We review your crash against each one to find out whether a broken rule played a part.
After a Truck Crash: Steps That Help Us Spot a Violation
Get medical care right away.
Most injuries in truck crashes happen to the occupants of other vehicles. Your treatment record comes first.
Photograph the truck's identifying numbers.
The company name and numbers on the cab identify the carrier whose safety records we’ll examine.
Notice the driver's condition.
Signs of drinking, exhaustion, or illness can point to alcohol, hours-of-service, or health-screening violations.
Note the truck's condition.
Smoking brakes, worn tires, or loose equipment may mean a pre-trip inspection was skipped.
Leave the rules to us.
Don’t try to confront the driver or the company about regulations at the scene or on the phone with their insurer.
Call a truck accident lawyer early.
Driver files, inspection reports, and hours records are held by the carrier. The sooner we ask, the more we can preserve.
Who Pays When a Federal Rule Is Broken?
The truck driver
A driver who drove past the hours limit, drank, or skipped an inspection is responsible for the harm that followed.
The trucking company or owner
Carriers must make sure their drivers are licensed, screened, and rested, and their trucks inspected. A company that let a violation happen can be liable too.
The required commercial insurance
Trucking companies and owner-operators must carry more liability insurance than ordinary drivers. Your claim is typically filed with the truck owner’s insurer.
Your losses
Medical expenses, lost wages and earning capacity, and psychological harm such as emotional distress.

How We Use Federal Trucking Laws to Prove Fault
Every driver has a duty of care to act reasonably to avoid harming others. For truck drivers and the companies that employ them, that responsibility is even greater, and the federal rules spell out much of what it requires.
We compare what happened in your crash with what the rules demanded:
- Were the driver’s hours within the limits, or was the driver past due for a mandatory break?
- Did the driver hold a valid commercial driver’s license and meet its training requirements?
- Was the driver current on the required physical health screening?
- Was there alcohol in the driver’s system, even below the limit for ordinary drivers?
- Was the pre-trip inspection actually done, and done properly?
- Does the company carry the insurance federal law requires?
A violation doesn’t just explain the crash. It shows that the driver or trucking company chose to skip a safety rule, and that is compelling evidence of negligence in negotiations and in court.
Key Federal Trucking Rules
Hours of service
Federal rules limit how long a driver can operate a truck before taking a mandatory break, to prevent fatigued driving.
Commercial driver's license (CDL)
To drive a commercial truck legally, a driver must hold a CDL, which requires special training and meeting certain requirements.
Health screenings and alcohol limits
Drivers must undergo regular physical health screenings. Under FMCSA regulations, the blood alcohol concentration limit for commercial truck drivers is 0.04%, lower than the limit for other drivers.
Pre-trip inspections and insurance
Drivers must inspect the truck before each trip, and carriers must carry higher liability insurance. Violating any of these rules can support your claim; under California’s pure comparative negligence rule, your own share of fault, if any, only reduces your recovery.

Federal Trucking Law FAQs
Which agency sets the federal trucking rules?
The Federal Motor Carrier Safety Administration (FMCSA). Its regulations apply to commercial truck drivers and trucking companies, including those operating in and around San Jose.
Does a broken federal rule automatically mean I win?
Not automatically, but it is strong evidence of negligence. We still need to show the violation contributed to the crash and your injuries, and we use the driver’s and company’s records to do that.
What is the alcohol limit for truck drivers?
Under FMCSA regulations, 0.04% blood alcohol concentration for commercial truck drivers, lower than the limit for ordinary drivers.
What if the driver didn't have a commercial license?
Driving a commercial truck without a CDL is itself a violation, and a company that put an unlicensed driver on the road may share responsibility for the crash.
Who do I file a claim against?
Usually the truck owner’s insurance company. Depending on the facts, the driver, the trucking company, and other parties may all be responsible.
Can I still recover if no federal rule was broken?
Yes. Every driver owes a duty of care. Speeding, distraction, or careless driving can prove negligence without any trucking-specific violation.
How long do I have to file?
Generally two years from the date of injury in California, and only six months for a claim involving a government vehicle.
What does hiring you cost?
Nothing upfront. We work on contingency; you pay a fee only if we recover for you.
