California is home to some of the busiest and most dangerous highways in the country. Thousands of trucks are on the roads all the time. This is particularly dangerous when a car slides beneath a truck, known as an underride truck accident. Truck accidents are always serious, and you may wonder why underride truck accidents are among the deadliest in California.
Understanding the physics and mechanics of how these crashes occur and the forces they exert on victims during impact can help explain their severity. The following provides an overview of the circumstances and vehicle damage involved in underride accidents.

Easton & Easton has extensive experience handling complex truck accident cases for people who have suffered serious injuries or the loss of a loved one due to a collision with a commercial vehicle. The firm’s attorneys investigate these types of accidents through accident reconstruction, evaluation of regulatory standards, and other factors.
Easton & Easton has successfully represented injury victims in claims involving both federal trucking standards and numerous liable parties. As such, the firm has extensive legal and factual insight into the manner in which underride and other catastrophic truck accidents are investigated and litigated in California.
Why Underride Collisions Are Devastating
As mentioned above, one of the ways in which underride collisions are more devastating to passenger vehicle occupants is that the point of impact may be above the hood line. This completely circumvents the vehicle’s safety equipment, such as airbags, crumple zones, and reinforced frames.
The result of a collision with a truck’s trailer or moon-roof is occupants being subjected directly to the force of the trailer’s vertical face, which is often unyielding. This is in contrast to other types of rear-end collisions and can cause head, neck, and chest injuries, as well as roof intrusion or decapitation.
The fact that the dimensions of trucks and cars are not aligned is one of the primary factors that can lead to these collisions, producing a disproportionately high number of fatalities.
Why Truck Design and Guard Limitations Matter
Rear underride guards are not expected to stop a passenger vehicle from sliding beneath a trailer. Design variations in rear guards are an issue, and many aftermarket trailer underride guards will fail at highway speeds or in offset or angled collisions. Side underride protection is not required on trailers, leaving long areas along the trailer sides where passenger vehicles can slide underneath the trailer.
The structure of trailers and tractor-trailers themselves presents underride risks. Current requirements for truck underride guards may be met and still not provide proper protection against underride in a crash. Guard strength, mounting location, and crash conditions all affect the real-world efficacy of underride protection in a crash, and the potential for critical injury if a vehicle slides under a truck.
Injuries in Underride Accidents
Underride accidents are a cause of the severe and catastrophic injury patterns seen in large truck collisions. The National Highway Traffic Safety Administration reports that more than 114,000 people were injured in large truck crashes in the United States in 2023.
In the same year, 5,472 people were killed in large truck crashes, most of those in the other vehicle in the collision. The larger size and force of commercial trucks make collisions with these vehicles and their trailers life-altering or deadly, and underride is one cause of truck crash injuries.
Underride Injuries on California Roadways
Highways, freeways, congested commuter routes, and commercial truck traffic can all raise the likelihood of underride. California freeways, including Interstate 10, Interstate 5, and major truck logistics corridors, are all major routes for constant tractor-trailer traffic that can lead to underride accidents.
Cars and trucks are frequently using the same highway lanes at highway speeds, and congestion, unexpected stops, and blind spots at night can lead to rear and side underride accidents. In busy freight corridors, lane changes, stopped traffic, and pull-overs can also lead to underride crashes. Road design, lighting, and traffic flow all influence how underride crashes happen on California roads.
FAQs
Are Underride Crashes Riskier Than Other Types of Truck Accidents?
While all truck accidents present significant risks, underride crashes are more likely to result in catastrophic injuries or fatalities due to the mismatch in vehicle heights and the exposure of occupants to undeformed, rigid structures.
Underride accidents are particularly dangerous because the passenger vehicle can bypass critical safety features and structures designed to absorb energy and protect occupants during a collision. The vehicle often intrudes directly into the occupant space, leading to a higher risk of severe or fatal injuries.
Can Federal Standards Guarantee the Prevention of Underride Accidents?
Federal standards mandate rear underride guards on most trailers; however, these requirements do not guarantee prevention. The performance of these guards can vary based on factors like collision speed, angle, and the physical condition of the guard.
Side underride protection is not uniformly required, leaving many trailers without safeguards on their sides. Compliance with regulations does not always translate to effective crash protection in real-world scenarios.
Can Poor Visibility Be a Factor in Underride Collisions?
Yes, poor visibility due to inadequate lighting, lack of reflective markings, and driving conditions, such as nighttime driving, can contribute to underride collisions. Difficulty in seeing a trailer, especially if it’s stopped or moving slowly, can delay driver reaction time and increase the likelihood of a vehicle sliding underneath. These factors are often considered in investigations to determine how an underride crash occurred.
Why Are Underride Accidents Often Fatal Even at Lower Speeds?
Underride accidents can be fatal even at lower speeds because the point of impact often occurs at the windshield or roof level. This leaves occupants vulnerable to severe head and neck trauma before airbags or seatbelts can mitigate the effects. The lack of energy-absorbing structures at the point of contact significantly contributes to the severity of these crashes.
Contact a Truck Accident Lawyer
Underride truck accidents are among the deadliest crashes on California roadways, largely due to differences in vehicle height, structural design, and underride guard limitations. These collisions often result in catastrophic or fatal injuries because the passenger vehicle slides beneath the truck, bypassing airbags and other safety features and exposing occupants to extreme force.
Unlike other truck accidents, underride crashes involve unique mechanical and roadway factors that increase injury severity. Easton & Easton handles serious truck accident claims involving underride collisions and conducts detailed evaluations to determine how these crashes occur and whether safety standards or regulations were violated.
