The types of accidents that are unique to commercial trucks include jackknife accidents, underride collisions, wide–turn accidents, and lost-load incidents. The size and weight of commercial trucks create risks that don’t typically apply to smaller vehicles.
As a result, the aftermath of a commercial truck accident can be overwhelming and stressful in very unique ways. If you or a loved one has been involved in a truck accident, it’s important to act quickly by contacting an Indianapolis truck accident lawyer as soon as possible.
A Closer Look at the Types of Accidents Unique to Commercial Trucks
Commercial trucks can be involved in a wide array of accidents that differ from typical vehicle collisions. The following types of collisions are unique to commercial trucks:
- Jackknife accidents
- Underride collisions
- Rollover crashes
- Wide turn accidents
- Lost load incidents
Jackknife Accidents
Jackknife accidents happen when the trailer of a commercial truck swings around the side of the vehicle and creates a “V” shape with the cab. Often caused by truck drivers who lose control of their vehicles, these accidents can block multiple lanes of traffic.
They often cause a chain reaction and result in a larger crash that involves other vehicles on the road. Not only does the need to brake suddenly contribute to jackknife accidents, but improper load distribution or failure to maintain the truck’s braking system can also play a role.
Underride Collisions
An underride accident occurs when a smaller vehicle crashes into the back of a commercial truck and slides underneath the truck’s trailer. The impact from an underride crash can be deadly because the force of the collision can crush the smaller vehicle beneath the truck.
This type of accident is particularly dangerous for occupants of the smaller vehicle because the impact typically results in property damage to the car’s roof and passenger compartment. In many cases, these accidents result in fatalities.
Underride collisions are especially common at night or in the face of poor visibility. These conditions can create a situation where smaller vehicles fail to see the truck’s brake lights, and in turn, they are more likely to crash into the commercial truck and become trapped.
Rollover Crashes
Rollover accidents involve a truck tipping over and landing on its side or the roof. Commercial trucks are particularly vulnerable to rollover accidents because of their high center of gravity, especially when they are carrying a heavy load.
Several factors can contribute to a truck rollover:
- Sharp turns
- High speeds
- Slippery roads
- Uneven weight distribution
Wide Turn Accidents
Wide turn accidents take place when a commercial truck makes a wide turn—either intentionally or unintentionally—and collides with other vehicles. These accidents are common when trucks are turning in busy intersections or trying to move through tight spaces.
Due to the large size of commercial trucks, they require more space to make turns than smaller vehicles. If a truck driver isn’t careful while making a wide turn, they may not see smaller vehicles in the blind spots, which can lead to a crash.
Lost Load Incidents
Brake failure accidents are another type of crash unique to commercial trucks. These accidents happen when a truck’s braking system malfunctions. As a result, the driver usually loses control of the vehicle.
Improper maintenance, worn-out brake pads, or excessive weight on the truck can all contribute to brake failure. It could also be caused by a lack of regular maintenance, including failure to check brake pads, fluids, and the overall brake system.
Additionally, trucks that are overloaded or carrying excessive weight may place too much stress on the brakes, leading to premature wear. When a truck’s brakes fail, it can be difficult for the driver to stop or slow the vehicle, leading to catastrophic collisions.

The Attention It Deserves

How Does Truck Size and Weight Contribute to Unique Accident Types?
The size and weight of commercial trucks contribute to unique accident types because these factors compound the severity of collisions. Commercial trucks are more dangerous than standard vehicles because their size and weight make it harder for drivers to stop quickly.
This is especially true when commercial truck drivers are traveling at high speeds. Commercial trucks require a greater stopping distance as well, but if a truck driver cannot brake in time to avoid the traffic ahead, rear-end collisions are common.
Additionally, the height and ground clearance of commercial trucks increases the likelihood of underride accidents. Meanwhile, jackknife accidents are common when drivers have to brake quickly and lose control in the process. The high center of gravity also contributes to rollovers.
What Role Does Cargo Play in Commercial Truck Accidents?
When cargo is incorrectly loaded or improperly secured, truck accidents are more likely. This is because overloaded or unevenly distributed cargo can affect the stability of trucks. These vehicles are at a greater risk of rolling over while in motion.
Furthermore, if the weight of the cargo is not safely balanced, trucks can become harder to control, especially when drivers are making sharp turns or braking suddenly. Additionally, exceeding legal weight limits can put excessive strain on the truck’s brakes and tires.
In turn, the likelihood of mechanical failures that could lead to an accident increases. Cargo can also pose a major threat to the safety of everyone on the road if objects fall off of trucks and hit other vehicles. Loose cargo inside trailers can make trucks more difficult to maneuver as well.
