SambaSafety’s 2026 Driver Risk Report analyzes millions of motor-vehicle records, telematics events, regulatory records, and insurance claims to identify trends in driver behavior and roadway risk.

For people involved in a serious truck accident, the report provides an important reminder: understanding why a commercial vehicle crash occurred often requires looking well beyond the accident itself.

Large Trucks Continue to Present Significant Safety Risks

One of the report’s most significant findings concerns large trucks.

According to the report, large-truck involvement in fatal crashes has increased substantially since 2009. The data demonstrates the continuing dangers associated with commercial motor vehicles and the enormous consequences that can result when a commercial driver makes a serious mistake.

A collision involving an 80,000-pound tractor-trailer is fundamentally different from an ordinary passenger-vehicle accident. The size and weight of commercial trucks can turn relatively small driving errors into catastrophic crashes.

That makes driver qualification, training, supervision, and compliance with safety regulations particularly important.

Speeding Remains a Major Problem

Speeding continues to be one of the leading driver violations identified in the report.

The report indicates that speeding accounts for approximately 36.5% of major violations and has remained the leading major violation since 2020.

Speed is particularly important in truck accidents because commercial vehicles require substantially more distance to stop and can cause devastating injuries when traveling at excessive speeds.

When a serious truck crash occurs, determining the truck’s speed before the collision can therefore be an important part of the investigation.

Electronic data, event data recorders, telematics systems, GPS information, onboard systems, video footage, and other evidence may help establish what the truck was doing immediately before the crash.

Distracted Driving Is Also Increasing

The report identifies another troubling trend: distracted-driving violations increased 31% over a two-year period.

Distraction can take many forms. A commercial driver may be looking at a phone, interacting with an electronic device, adjusting equipment, looking away from the roadway, or otherwise failing to devote the attention required to safely operate a large commercial vehicle.

For a truck driver, even a few seconds of inattention can have catastrophic consequences.

That is why an investigation of a serious commercial-truck collision should consider more than whether the driver received a citation. Evidence concerning cellphone use, electronic devices, onboard technology, dash cameras, and company policies may be relevant to determining what happened.

Fatigue and Poor Sleep Are Important Safety Concerns

Fatigue is another significant issue discussed in the report.

SambaSafety’s analysis identifies a relationship between poor sleep and increased accident risk, highlighting the continuing importance of driver fatigue as a roadway-safety issue.

Fatigue has long been a concern in the trucking industry. Commercial drivers operate under federal hours-of-service regulations designed, in part, to reduce the dangers associated with excessive driving and inadequate rest.

But compliance cannot always be determined simply by asking whether a driver was technically within the hours permitted by regulation.

In an appropriate case, investigators may need to examine electronic logging-device records, dispatch records, trip schedules, GPS information, communications between the driver and the company, and other evidence to understand whether fatigue played a role in the crash.

Trucking Violations Matter

The report also identifies hundreds of thousands of out-of-service violations involving commercial vehicles.

A violation by itself does not necessarily prove that a particular truck driver or trucking company caused an accident. But safety violations can provide important information when investigating a serious collision.

For example, an investigation may reveal issues involving:

• Driver qualification and licensing
• Hours-of-service compliance
• Vehicle maintenance
• Speeding
• Distracted driving
• Drug and alcohol testing
• Prior crashes
• Safety violations
• Driver training
• Company supervision
• Electronic logging records
• Telematics and vehicle data

The important question is often not simply “What happened in this crash?”

It is also:

“What did the trucking company know, what should it have known, and what did it do about the risks?”

A Truck Accident Investigation Should Go Beyond the Police Report

After a serious truck accident, the police report is important—but it is only one piece of the evidence.

A thorough investigation may require obtaining and examining records that are not available at the scene of the crash.

Those records can include the driver’s motor-vehicle history, commercial driver’s license records, inspection and maintenance records, hours-of-service information, electronic logging data, driver qualification materials, company safety records, communications, GPS data, telematics information, and available video.

Some electronic evidence can also be overwritten, lost, or otherwise become more difficult to obtain as time passes.

That is one reason early investigation and preservation of evidence can be so important in a serious trucking case.

What This Means for People Injured in Truck Crashes

The 2026 Driver Risk Report does not tell us why any particular truck accident occurred. Instead, it provides broader data showing that speeding, distraction, fatigue, regulatory violations, and other forms of driver risk remain serious safety concerns.

For someone seriously injured in a commercial-truck collision, those findings reinforce an important point:

The cause of a truck accident may not be apparent from looking at the vehicles or reading the initial accident report.

Understanding what happened may require a detailed examination of the driver’s history, the trucking company’s safety practices, electronic data, regulatory compliance, and the circumstances leading up to the collision.

At The Hamilton Firm, we believe serious truck accident cases require that kind of investigation. Our goal is not simply to determine what happened at the moment of impact, but to understand why the crash happened and whether the driver, trucking company, or other responsible parties failed to follow the safety rules designed to prevent it.

Unfortunately, those duties are not always followed.

Federal Regulations Require Immediate Action

The Federal Motor Carrier Safety Regulations (FMCSRs) recognize that a disabled commercial vehicle presents an extraordinary hazard to approaching traffic. Under 49 C.F.R. § 392.22, a commercial motor vehicle that is stopped upon the traveled portion or shoulder of a highway for any reason other than a necessary traffic stop must immediately activate its hazard warning flashers.

The regulations go further. Within 10 minutes, the driver generally must place warning devices to alert approaching motorists. Those warning devices typically consist of three reflective triangles (or other approved warning devices) strategically positioned to provide adequate notice to drivers approaching from both directions.

The placement requirements vary depending upon where the truck is stopped:

• On a two-lane roadway.
• On a divided highway.
• Near a hillcrest, curve, or other obstruction limiting visibility.
• On or near an entrance or exit ramp.

The regulations require the warning devices to be positioned differently in each situation because the goal is to maximize the distance from which approaching motorists can recognize the hazard.

The Duty Begins Before the Warning Triangles

The warning triangle requirements are only one part of the driver’s responsibilities.

Before a truck ever becomes disabled, federal regulations require drivers to operate safely and remain constantly attentive to roadway conditions. 49 C.F.R. § 392.2 requires compliance with applicable state traffic laws unless a specific federal regulation provides otherwise.

Drivers are also prohibited from operating commercial vehicles when their ability to do so safely is impaired by fatigue, illness, or other conditions. See 49 C.F.R. § 392.3.

These regulations often become relevant when investigators examine why a truck came to be stopped in the roadway in the first place.

Maintenance May Be the Real Cause

Insurance companies frequently characterize roadway stoppages as unavoidable mechanical failures.

A thorough investigation often asks a different question:

Was the breakdown preventable?

Federal regulations require motor carriers to systematically inspect, repair, and maintain their commercial vehicles. Under 49 C.F.R. Part 396, trucking companies must maintain their equipment in safe operating condition and document inspections and repairs.

Investigators often examine:

• Brake maintenance records.
• Tire inspections.
• Air brake system repairs.
• Driver Vehicle Inspection Reports (DVIRs).
• Annual inspection reports.
• Maintenance histories.
• Prior out-of-service violations.

What initially appears to be an unavoidable breakdown may actually have resulted from months of deferred maintenance.

Visibility Can Mean the Difference Between Life and Death

The placement requirements found in 49 C.F.R. § 392.22 become even more important when a truck is stopped near a curve, hillcrest, or other location where approaching drivers have limited sight distance.

In those situations, the regulations require warning devices to be placed farther from the truck because motorists need additional time to recognize the hazard, perceive the danger, and react safely.

A fully loaded tractor-trailer can occupy nearly an entire lane of travel. At interstate speeds, drivers may have only seconds to avoid a collision.

Electronic Evidence Often Tells the Story

Modern commercial trucks generate enormous amounts of electronic information that can help determine what actually occurred before and after a roadside stop.

Depending upon the truck, investigators may obtain:

• Electronic Control Module (ECM) data.
• Event Data Recorder (EDR) information.
• Electronic Logging Device (ELD) records.
• GPS location history.
• Qualcomm or satellite communications.
• Dash camera video.
• Collision mitigation system data.

Combined with maintenance records and driver testimony, this evidence can establish whether the truck could have been moved farther from the roadway, how long it remained stopped, and whether the driver complied with federal safety regulations.

Every Roadway Stopping Case Deserves Careful Investigation

Not every truck that stops on the roadway is operated negligently. Mechanical failures and emergencies do occur.

However, a breakdown does not end the legal inquiry.

The important questions include whether the truck was properly maintained before the breakdown, whether the driver acted reasonably after stopping, and whether the trucking company complied with the Federal Motor Carrier Safety Regulations designed to protect the public.

Answering those questions often requires obtaining evidence before it disappears. Electronic data may be overwritten, maintenance records may change, and witnesses’ memories fade. Prompt investigation is frequently the key to determining why the truck stopped and whether the collision could have been prevented.

Trucking companies and their insurers often dispatch investigators immediately after a serious collision involving a disabled commercial vehicle. Their goal is to preserve evidence that supports the defense.

Injured victims deserve lawyers who understand federal trucking regulations, know how to preserve electronic evidence, and are prepared to present complicated trucking cases to a jury if necessary.
