Truck Accident Attorney in San Francisco Serving Throughout California

Accidents involving large trucks and commercial vehicles are among the most serious and deadly in the United States. With big rigs and 18-wheelers weighing in at up to 80,000 pounds (as opposed to the 5,000 pounds most passenger vehicles weigh), it is a matter of simple physics; a larger vehicle impacting a smaller vehicle is likely to result in catastrophic damages. The risk of being in an accident involving a large truck or big rig is particularly acute here in California; we have the highest volume of truck traffic of any state in the United States. In 2004, there were 415 fatalities within the State of California in accidents involving large trucks.

It is a common misconception that accidents involving large trucks are simply personal injury cases involving a larger vehicle; there are specific laws and regulations governing the safety of commercial motor vehicles and issues which are unique to cases involving commercial vehicles. These cases require a thorough understanding of commercial vehicle regulations on both the federal and state level.

Federal Law

The Federal Motor Carrier Safety Regulations (Title 49, Parts 350-399) govern all vehicles engaged in interstate traffic. To view the Federal Motor Carrier Safety Regulations, click here.

Federal law requires drivers and their employers to keep logbooks, fuel receipts and other trip documentation for six months and vehicle maintenance records for a year. When an accident occurs, they are required to preserve all relevant documents. There have been many documented cases where unscrupulous trucking companies have altered or forged records following an accident, especially with respect to the number of hours driven.

Interstate truckers are required to record, either in a written or digital “logbook,” the amount of time spent resting or driving. An interstate trucker is limited to 11 hours of driving over a 14-hour period and is required to rest for 10 straight hours before returning to the road. The foregoing driving limitation is subject to a number of different factors and exceptions, including adverse driving conditions, time spent in a sleeper berth, and type of cargo the truck is carrying.

Federal law requires that an employer verify a driver’s previous three years of experience. With an estimated 40,000 trucking companies going out of business each year, many trucking companies say it is difficult for them to verify a driver’s previous experience if a prior employer is no longer in business. Many trucking companies admit that they have placed drivers on the road without receiving a response from a prior employer.

When a large commercial truck is involved in an accident, the damages can be catastrophic. When a tanker truck carrying 8,600 gallons of explosive gasoline crashed and set fire to the East Bay’s MacArthur Maze in April, 2007, it melted the overpass and resulted in the closure of a key part of the Bay Area’s traffic infrastructure. Following the accident it was discovered that the driver had a troubled safety record, having been cited 27 times in 2-1/2 years for safety violations, and had prior felony convictions, including a conviction for possession of heroin. Many questioned how someone with the driver’s past could be allowed to legally drive a tanker truck loaded with flammable gasoline.

Common Factors Contributing to Accidents

The following factors are frequently cited as factors contributing to accidents involving large trucks.

  • Driver Fatigue
  • Improperly Trained or Inexperienced Driver
  • Driver Under the Influence of Drugs or Alcohol
  • Aggressive Driving
  • Driver with a history of dangerous or reckless driving
  • Speeding or driving too fast for road conditions
  • Oversized or overloaded vehicle
  • Unsafe reflectors, lights or other safety equipment on vehicle
  • Poorly maintained brakes
  • E-mailing while driving. There are actually large trucks which are equipped with a Qualcomm e-mail system mounted on the steering wheel, which allows the driver to send and receive e-mails. According to Qualcomm, these systems are in use in over 2,000 trucking fleets nationwide. Although the system is equipped with a safety device that can prevent the system from being used while the truck is in motion, many truck companies have failed to install this safety feature. E-mailing while driving has been cited as a cause of fatal crashes.


According to a new study released by the Federal Motor Carrier Safety Administration (FMCSA) in March of 2006 (the Large Truck Crash Causation Study detailed below), drivers of large trucks and other vehicles involved in truck crashes are ten times more likely to be the cause of the crash than other factors, such as weather, road conditions, and vehicle performance. Action or inaction by the driver of either the truck or other vehicle was cited as the critical reason for 88 percent of the crashes.

The Large Truck Crash Causation Study (LTCCS) is based on a three-year data collection project conducted by the Federal Motor Carrier Safety Administration (FMCSA) and the National Highway Traffic Safety Administration (NHTSA) of the United States Department of Transportation (DOT). LTCCS is the first-ever national study to attempt to determine the critical events and associated factors that contribute to serious large truck crashes so agencies within DOT and others can implement effective countermeasures to reduce the occurrence and severity of these crashes. The results of the study were released in March of 2006.

For the purposes of the LTCCS, a “truck” is defined as “a vehicle designed, used, or maintained primarily for carrying property, with a gross vehicle weight rating or gross combination weight rating of more than 10,000 lbs.” During the three-year study period of the project, FMCSA estimated that there were approximately 141,000 large trucks involved in fatal, incapacitating, and non-incapacitating injury crashes.
This table from the LTCCS shows the estimated number of trucks involved in crashes nation-wide by specific factors associated with the particular crash in which that truck was involved.

Advice for Truck Accident Victims

If you or a loved one have been involved in an accident involving a large truck:

  • Obtain medical treatment from a qualified physician or go to an emergency room as soon as possible.
  • Keep all medical appointments unless you have a documented reason for failing to keep the appointment. Insurance companies will sometimes attempt to use missed medical appointments as evidence of “failure to mitigate damages”, and will seek to reduce any compensation or settlement accordingly.
  • Keep accurate, detailed records of any time lost from work as a result of the accident, including the date and amount of time lost.
  • Keep records of any additional expenses you have incurred as a result of the accident, including receipts and proof of payment. You may wish to pay by check or credit card in order to have proof of payment.
  • Obtain photographs of the damage to your vehicle. It is important to obtain these photographs prior to sending the vehicle for repairs, to the insurance company for inspection, or to a salvage yard if the vehicle is a total loss.
  • Obtain photographs of the accident scene, capturing any skid marks, debris, traffic signs or signals, and the condition of the road.
  • Seek legal counsel immediately to preserve your legal rights. Legal representation is important to ensure that key evidence is properly obtained. It is not uncommon for trucking companies to withhold key evidence, including driver’s logs and maintenance records. It is important to obtain this evidence as soon as possible to prevent it from being lost or destroyed.
