Truck accidents are among the most devastating types of vehicle collisions on the road. When a large commercial truck, such as a semi-trailer or tanker, collides with a smaller passenger vehicle, the results can be catastrophic, often resulting in severe injuries or fatalities. One of the most alarming causes of these accidents is when truck people drive while under the influence of drugs or alcohol, posing significant risks to everyone on the road.
When truck drivers are intoxicated and cause accidents, victims are typically entitled to compensation. To learn more about your legal options, reach out to a San Diego truck accident lawyer today.

The Dangers of Impaired Truck Drivers

Driving a commercial truck requires high skill, concentration, and quick reflexes. These vehicles are significantly larger and heavier than passenger cars, requiring longer stopping distances and greater care when maneuvering. When a truck driver is under the influence of drugs or alcohol, their ability to safely drive is severely compromised.
Alcohol and many drugs can impair a driver's judgment, reaction time, coordination, and vision. This can lead to a variety of dangerous behaviors, such as:
Swerving or Drifting Out of Their Lane
One of the most common signs of an impaired truck driver is swerving or drifting out of their designated lane. Alcohol and drugs can affect a driver's ability to focus, maintain proper lane position, and make smooth steering corrections. This can cause the truck to weave back and forth between lanes or even cross over into oncoming traffic.
Swerving or drifting can be particularly dangerous when a large commercial truck is involved. These vehicles have a much larger turning radius than passenger cars, requiring more time and space to make lane changes or corrections. When an impaired driver fails to maintain proper lane position, they increase the risk of sideswiping other vehicles or causing a head-on collision.
Failing to Maintain a Safe Following Distance
Another common mistake impaired truck drivers make is failing to maintain a safe following distance behind other vehicles. Alcohol and drugs can slow a driver's reaction time and impair their judgment, making it more difficult for them to respond quickly to changes in traffic or sudden stops.
When a truck driver follows too closely behind another vehicle, they may not have enough time to brake or take evasive action if the vehicle in front of them slows down or stops suddenly. This can result in rear-end collisions, which can be particularly devastating when a large commercial truck is involved.
To help prevent these types of accidents, the Federal Motor Carrier Safety Administration (FMCSA) has established guidelines for safe following distances for commercial trucks. Drivers must maintain a minimum following distance of one second for every 10 feet of vehicle length and should increase that distance in adverse weather or traffic conditions.
Running Red Lights or Stop Signs
Impaired truck drivers may also be more likely to run red lights or stop signs, putting themselves and others at risk of serious accidents. Alcohol and drugs can impair a driver's ability to perceive and react to traffic signals and can also lead to reckless or aggressive driving behaviors.

Running a red light or stop sign is a serious traffic violation that can result in devastating accidents. When a large commercial truck runs a red light, it can collide with vehicles traveling through the intersection from other directions, causing serious injuries or fatalities.
Truck drivers caught running red lights or stop signs can face severe legal consequences, including fines, license suspension, and criminal charges. In addition, if an impaired truck driver causes an accident by running a red light or stop sign, they and their employer may be liable for any resulting damages or injuries.
Speeding or Driving Too Slowly for Conditions
Impaired truck drivers may also have difficulty maintaining an appropriate speed for the road and traffic conditions. Alcohol and drugs can affect a driver's perception of speed and distance, causing them to drive too fast or too slowly for the circumstances.
Speeding is a major contributing factor in many truck accidents. When a large commercial truck travels at an excessive speed, it requires more time and distance to slow down or stop, increasing the risk of a collision. Speeding can also make it more difficult for a truck driver to safely navigate curves, hills, or other road features.
On the other hand, driving too slowly can also be dangerous, particularly on highways or other high-speed roads. A truck driver traveling significantly below the posted speed limit can create a hazard for other vehicles that may need to slow down or change lanes to avoid a collision.
Failing to Yield the Right of Way
Impaired truck drivers may also have difficulty recognizing and responding to situations requiring them to yield the right of way to other vehicles or pedestrians. Alcohol and drugs can impair a driver's judgment and decision-making abilities, causing them to misjudge the speed or distance of oncoming traffic or fail to see pedestrians or other vehicles altogether.
Failing to yield the right of way can result in serious accidents, particularly when a large commercial truck is involved. For example, if a truck driver fails to yield to oncoming traffic when making a left turn, they can cause a devastating head-on collision. Similarly, if a truck driver fails to yield to a pedestrian in a crosswalk, they can cause serious injuries or fatalities.
Truck drivers who fail to yield the right of way can face legal consequences, including traffic citations and civil liability for any resulting accidents or injuries. In addition, if an impaired truck driver causes an accident by failing to yield, they and their employer may be held responsible for any resulting damages.
Falling Asleep at the Wheel
Perhaps one of the most dangerous consequences of impaired driving for truck drivers is the risk of falling asleep at the wheel. Alcohol and many drugs, including prescription and over-the-counter medications, can cause drowsiness and fatigue, making it more difficult for a driver to stay awake and alert behind the wheel.
Falling asleep at the wheel is a major factor in many truck accidents. When truck drivers fall asleep, they lose control of their vehicles, putting themselves and others at risk of serious accidents. A sleeping truck driver can drift out of their lane, run off the road, or collide with other vehicles or objects.

To help prevent fatigued driving, the FMCSA has established hours-of-service regulations limiting the number of hours a truck driver can drive daily and weekly. Drivers are required to take regular breaks and to get adequate rest between shifts. However, impaired drivers may be more likely to violate these regulations or underestimate their level of fatigue, putting themselves and others at risk.
If a truck driver causes an accident by falling asleep at the wheel, they and their employer may be held liable for any resulting damages or injuries. Victims of these accidents can seek compensation for medical expenses, lost income, pain and suffering, and other damages through a personal injury lawsuit.
The Legal Consequences for Impaired Truck Drivers
Truck drivers who choose to drive while under the influence of drugs or alcohol face severe legal consequences. In addition to the criminal penalties for driving under the influence (DUI) or driving while intoxicated (DWI), which can include fines, license suspension, and even jail time, impaired truck drivers can also face civil liability for any accidents they cause.
Trucking companies must have liability policies to cover damages and injuries caused by their drivers. If a truck driver causes an accident while under the influence, the victims can seek compensation from the trucking company's insurance policy. This can include compensation for medical expenses, lost income, pain and suffering, and other damages.
A trucking company might be responsible for a crash caused by a drunk driver. This happens when the company neglects to hire, train, or supervise well. For example, it may not check a driver's background. Or, can hire a driver with DUI convictions. Additionally, if the company ignores a driver's substance abuse problem, it can be liable for any resulting accidents.
The best way for victims to hold drivers and trucking companies accountable is to retain a truck accident attorney as soon as they can after a truck accident.
The Role of Federal Regulations
The FMCSA has established strict regulations to prevent truck drivers from operating their vehicles while under the influence of drugs or alcohol.
These regulations include:
- A prohibition on driving with a blood alcohol concentration (BAC) of 0.04 percent or higher (the legal limit for most drivers is 0.08 percent)
- Mandatory pre-employment drug testing for all new truck drivers
- Random drug and alcohol testing for current drivers
- Post-accident drug and alcohol testing for drivers involved in certain types of accidents
- A requirement that drivers who test positive for drugs or alcohol or who refuse a test be immediately removed from duty and referred to a substance abuse professional for evaluation and treatment
Trucking companies must follow these rules. They must also keep records of their compliance. Failure to do so can result in fines, penalties, and even the loss of the company's operating authority.
The Importance of Holding Impaired Truck Drivers Accountable

Despite these regulations and the severe consequences of impaired driving, some truck drivers still choose to get behind the wheel while under the influence of drugs or alcohol. When these drivers cause accidents, they must be held accountable for their actions.
Holding impaired truck drivers accountable serves several important purposes:
- It provides a measure of justice for the victims of these accidents and their families.
- It strongly conveys that the trucking industry will not tolerate impaired driving.
- It encourages trucking companies to take proactive steps to prevent impaired driving, such as improved hiring and supervision practices and better employee education and support programs.
- It helps to make the roads safer for everyone by removing dangerous drivers from the road and deterring others from engaging in similar behavior.
