In 2022, the Federal Motor Carrier Safety Administration (FMCSA) reported 114,000 large-truck injury crashes, underscoring the significant dangers posed by 18-wheelers on our roads. Unlike passenger vehicle accidents, truck crashes often involve multiple parties and are governed by a complex set of federal regulations. The sheer weight of a truck—up to 80,000 lbs—coupled with black box (ECM) evidence, makes these incidents particularly severe and complicates the process of proving liability in personal injury claims.
In this guide, we’ll break down the most common causes of truck accidents in Georgia, why each is so dangerous, and who may be held liable depending on the circumstances.
Jackknife Accidents
A jackknife accident occurs when a truck’s trailer swings out to the side of the cab, forming a “V” or jackknife shape.
Common Causes:
- Sudden braking, especially when driving too fast for conditions.
- Slippery roads, particularly in wet conditions.
- Brake failure, either due to poor maintenance or faulty components.
- Improper braking techniques or excessive speed.
Local Relevance:
In Georgia, congested roads on I-285 and I-75 are prime locations for these types of accidents, especially during rainy weather.
Why It’s Dangerous:
When a truck’s trailer jackknifes, it can block multiple lanes of traffic, posing a danger to multiple vehicles at once.
Liable Parties:
- Driver: If the driver was speeding or used improper braking techniques.
- Trucking Company: If the company failed to maintain the vehicle or provide proper training for the driver.
- Cargo Loader: If the cargo was improperly loaded or the weight was not evenly distributed, the truck can lose stability.
Truck Rollover Accidents
Truck rollover accidents occur when a commercial truck tips onto its side or roof due to a collision, a sharp turn, or an external force such as high winds. Trucks are more prone to rollovers than passenger vehicles due to their high center of gravity.
Common Causes:
- Taking curves or exit ramps too quickly.
- Overloaded or improperly loaded cargo that shifts during travel.
- Wind conditions that affect the truck’s stability.
- Overcorrection during a maneuver or a sudden move by the driver.
Note:
Empty trailers are more prone to rollovers than fully loaded trucks because they weigh less and therefore have less traction.
Liable Parties:
- Driver: If speeding or improper turning caused the accident.
- Trucking Company: If the cargo was loaded improperly, or the driver was not adequately trained.
- Cargo Company: If the cargo was not properly secured and in violation of industry standards.
Rear-End Truck Collisions
Rear-end truck collisions occur when a truck crashes into the back of a slower or stopped vehicle. Due to their weight, large commercial trucks require approximately the length of two football fields to stop—significantly more space than a passenger car.
Common Causes:
- Following too closely behind other vehicles.
- Distracted driving, such as texting or looking away from the road.
- Speeding, which reduces the time needed to stop.
- Brake failure or lag, especially if the truck’s brake system is not properly maintained.
- Driver fatigue, which can impair reaction time and judgment.
Injuries:
Rear-end collisions involving trucks often result in severe injuries, as the force of impact can push smaller vehicles forward or crush them entirely.
Liable Parties:
- Driver: If they were following too closely, driving distracted, or speeding.
- Trucking Company: If the company failed to maintain the brakes or caused driver fatigue by violating hours of service regulations
Head-On Collisions
Head-on collisions are among the deadliest types of truck accidents, where the front of a truck strikes the front of another vehicle. The combined speed and mass of 18-wheelers make these collisions highly dangerous, often resulting in fatal or catastrophic injuries.
Common Causes:
- Wrong-way driving, such as entering a highway in the wrong direction.
- Drifting across the centerline due to driver fatigue or intoxication.
- Unsafe passing on two-lane roads.
- Driver fatigue, which can cause the driver to fall asleep at the wheel.
Note:
Head-on collisions often result in wrongful death claims due to the severity of the impact.
Liable Parties:
- Driver: If the driver was driving the wrong way or fell asleep behind the wheel.
- Trucking Company: If hours of service violations were found in the driver’s logs, indicating fatigue or overwork.
T-Bone (Side-Impact) Truck Accidents
A T-bone truck accident occurs when the front of a truck strikes the side of another vehicle, forming a “T” shape.
Common Causes:
- Running red lights or failing to yield at intersections.
- Distracted driving at intersections or failing to notice traffic signals.
- Fatigued or rushed driving.
Liable Parties:
- Driver: If they committed a traffic violation or were distracted.
- Trucking Company: If the driver was fatigued due to improper scheduling or negligent hiring.
Sideswipe Accidents
A sideswipe accident occurs when a truck’s side scrapes along the side of another vehicle, typically during a lane change or merge. Given the large blind spots of commercial vehicles, these types of truck accidents are fairly common.
Common Causes:
- Failure to check mirrors or use proper lane change techniques.
- Distracted driving, such as texting or engaging with in-cab technology.
- Fatigue-related drifting, especially during long-haul trips.
- Improper lane change technique, including cutting in too early or too late.
Liable Parties:
- Driver: If the driver failed to check blind spots or changed lanes improperly.
- Trucking Company: If the company failed to equip the truck with functioning mirrors or cameras, or if the driver received inadequate training on safe lane change practices.
Blind Spot Accidents
Blind spot accidents occur when a truck merges into a car that is located in its “no-zones”—areas where the truck driver cannot see the surrounding vehicles. Unlike passenger cars, semi-trucks lack rearview mirrors and rely entirely on side mirrors and cameras, which can fail or be misused.
Common Causes:
- A truck merges into an adjacent lane or drifts into another lane without noticing a vehicle in its blind spot.
- A truck backs up at a loading dock and strikes a vehicle that was in the blind spot.
Legal Duty:
Truck drivers have a legal obligation to check their blind spots before every lane change or maneuver. Failure to do so can result in serious accidents.
Liable Parties:
- Driver: If the driver failed to check blind spots before merging or changing lanes.
- Trucking Company: If the company failed to provide adequate mirrors, cameras, or training on safe driving practices.
Wide Turn (Squeeze Play) Accidents
Wide turn accidents, also known as squeeze play accidents, occur when a semi-truck must swing left to complete a right turn, trapping vehicles in the right lane between the truck and the curb. This maneuver often requires two lanes, and if the truck is not careful, its rear wheels can clip the curb or run over vehicles.
Common Causes:
- Failure to signal before the turn.
- Other drivers failing to recognize the wide turn setup.
- Taking the turn too fast or not positioning the truck correctly.
Liable Parties:
- Driver: If the driver failed to signal or made the turn improperly.
- Trucking Company: If the company’s training was inadequate or if they failed to emphasize the importance of proper turn techniques.
Underride Accidents
Underride truck accidents occur when a smaller vehicle slides under the rear or side of a truck’s trailer during a collision. This is one of the most catastrophic—in some cases, fatal— types of accidents, as the top of the passenger vehicle can be sheared off entirely.
Common Causes:
- Sudden braking by the truck, causing the smaller vehicle to slide underneath the rear of the trailer.
- Wide turns or unexpected lane changes that trap the smaller vehicle under the truck.
- Lack of rear or side underride guards.
Regulatory Note:
Federal law mandates rear underride guards (ICC bumpers) on trailers to prevent vehicles from sliding underneath. However, side underride guards are not federally required, creating a significant gap in safety standards.
Liable Parties:
- Driver: If the driver made a sudden stop or unexpected maneuver that caused the collision.
- Trucking Company: If the company failed to maintain or repair the rear underride guard, or if they didn’t properly train their drivers on safe braking practices.
- Manufacturer: If the underride guard was defective or non-compliant with federal regulations.
Tire Blowout Accidents
A tire blowout accident happens when a truck’s tire fails unexpectedly while in motion, leading to a loss of control. Commercial truck tires bear immense loads, so a single tire failure can have catastrophic consequences for the driver and surrounding vehicles.
Common Causes:
- Underinflated tires, which can cause the rubber to overheat and fail.
- Overloaded trucks put excessive strain on the tires.
- Worn-out tread or defective manufacturing that weakens the tire.
- Failure to conduct federally required pre-trip tire inspections.
FMCSA Requirement:
FMCSA mandates pre-trip inspections, including tire checks. Failure to inspect tires is considered negligence and could result in the trucking company being held liable for the accident.
Is a Tire Blowout an At-Fault Accident?
Yes – tire blowouts are considered at-fault accidents when caused by inadequate maintenance, improper loading, or failure to inspect before the trip.
Liable Parties:
- Driver: If the driver failed to inspect the tires or noticed signs of wear but continued to drive.
- Trucking Company: If the company did not maintain or properly inspect the tires before the trip.
- Tire Manufacturer: If the tire was defective and caused the blowout, the manufacturer may be held liable for product defects.
Cargo Spill and Lost Load Accidents
Cargo spill accidents occur when improperly secured cargo falls from a truck onto the road, creating hazards or striking other vehicles. Spilled cargo can cause other vehicles to crash or lead to dangerous road conditions that result in additional accidents.
Common Causes:
- Improperly securing the cargo, such as failing to use tie-downs or restraints.
- Inadequate loading practices, where the cargo is unbalanced or too heavy for the truck’s capacity.
- FMCSA violations of cargo securement standards, which are critical for preventing load spills.
FMCSA Regulation:
FMCSA outlines cargo securement standards under 49 CFR Part 393. Failure to adhere to these regulations is a direct basis for negligence.
Liable Parties:
- Driver: If the driver failed to properly secure the load or overlooked potential hazards during loading.
- Trucking Company: If the company’s loading practices were negligent, or if they failed to ensure that the driver was trained in cargo securement standards.
- Cargo Loading Company: If the cargo was improperly loaded at the origin, violating FMCSA regulations and creating an unsafe load.
What Causes Most Truck Accidents? Understanding Negligence
Negligence occurs when a party fails to exercise reasonable care, resulting in an accident and injuries.
What Causes Truck Accidents? And How Negligence Plays a Role:
- Driver Error: This can include fatigue, distraction, speeding, intoxication, and failure to obey traffic laws.
- Trucking Company Negligence: Unrealistic delivery schedules, hours of service violations, failure to maintain vehicles, or lazy hiring practices.
- Equipment Failure: Brake failure, tire blowouts, defective lighting, or faulty cargo securement equipment.
- Cargo Loading Negligence: Improperly loaded or overloaded freight that shifts during transit and causes a crash.
- Third-Party Manufacturers: Defective parts, such as tires, brakes, or hitches, can lead to loss of control and accidents.
What Is Negligence in Truck Accidents?
Negligence in truck accidents refers to a failure to exercise reasonable care, and it can apply to multiple parties—driver, company, loader, and even the manufacturer. In truck accident cases, FMCSA violations can serve as evidence of negligence.
