Snoqualmie Pass semi crash and a separate brush fire caused major traffic disruptions along Interstate 90 on Monday, affecting drivers traveling through Cle Elum and Snoqualmie Pass. The brush fire temporarily shut down westbound I-90 near Cle Elum, while hours later a serious semi-truck collision closed all eastbound lanes near the Snoqualmie Pass summit.

At least one person suffered serious injuries in the semi-truck crash and was reportedly airlifted from the scene. Emergency crews remained on the interstate as Washington State Patrol investigated the collision and worked to safely reopen the roadway.

The two incidents created hours of delays along one of Washington’s most important east-west transportation corridors.

Brush Fire Closes Westbound I-90 Near Cle Elum

The first disruption began at approximately 2:30 p.m. when a brush fire broke out near Cle Elum.

Heavy smoke was reported along the interstate, creating potentially dangerous driving conditions and forcing authorities to close westbound I-90 while firefighters responded.

Kittitas County firefighters quickly worked to contain the fire. Westbound I-90 remained fully closed for approximately an hour and a half before reopening around 4 p.m.

Smoke can create serious hazards on highways even when flames do not reach the roadway. Rapidly changing visibility, stopped traffic, emergency vehicles and drivers attempting to avoid smoke can all increase the risk of a collision.

Drivers traveling through the area can monitor official road conditions through the Washington State Department of Transportation’s Snoqualmie Pass travel information. WSDOT maintains cameras, restrictions and alerts for the I-90 corridor between Cle Elum and North Bend.

Snoqualmie Pass Semi Crash Closes Eastbound I-90

Several hours after the brush fire, another serious incident disrupted traffic near the Snoqualmie Pass summit.

At approximately 7:30 p.m., Washington State Patrol Trooper Rick Johnson reported that a semi-truck collision had closed all eastbound lanes of I-90 near the summit.

At least one person reportedly suffered serious injuries, and a LifeFlight helicopter was requested to assist with the emergency response. The injured person was airlifted from the crash scene for medical treatment.

One eastbound lane was eventually reopened, but significant delays continued while investigators and emergency crews remained at the scene.

Initial reports did not establish what caused the semi-truck crash. Until the investigation is completed, it would be premature to determine whether driver error, vehicle problems, roadway conditions or another factor caused or contributed to the collision.

Washington State Patrol Investigates Serious I-90 Crashes

The Washington State Patrol investigates serious collisions on Washington highways and maintains collision records for crashes investigated by troopers.

Drivers and injured parties can visit the Washington State Patrol for official information regarding traffic safety, collision investigations and public records.

WSP advises that collision reports may take approximately two to four weeks to become available after an investigation.

Obtaining the official collision report can be an important step following a serious accident, but it may not contain every piece of evidence relevant to a personal injury claim.

Semi-truck accidents can present legal questions that are substantially different from those involved in an ordinary passenger-vehicle collision.

Commercial trucks are large, heavy vehicles, and crashes involving them can result in catastrophic injuries. Determining why a collision occurred may require examining evidence held by the truck driver, trucking company or other businesses involved in operating and maintaining the vehicle.

Who May Be Responsible for a Semi-Truck Accident?

Depending on the circumstances of the collision, potentially responsible parties could include:

  • The semi-truck driver
  • The driver’s employer or trucking company
  • A company responsible for truck maintenance
  • A business responsible for loading or securing cargo
  • Another driver involved in the collision
  • A manufacturer if defective equipment contributed to the crash

Responsibility depends on the evidence. The presence of a commercial truck alone does not establish that the truck driver or trucking company was negligent.

Evidence That May Matter in a Truck Crash Investigation

Evidence in a serious commercial-truck collision may include photographs of the crash scene, witness statements, police reports, electronic logging records, onboard vehicle information, dash-camera footage, maintenance records and inspection documents.

A trucking company may also possess dispatch records, driver qualification information and other documents that could help establish what happened before the collision.

Preserving this information early can become particularly important when a crash results in severe injuries.

Can an Injured Person Recover Compensation After an I-90 Truck Crash?

A person injured because of another party’s negligence may be able to pursue compensation under Washington law.

Depending on the circumstances, damages in a personal injury claim can include medical expenses, future medical treatment, lost wages, reduced earning capacity, pain and suffering and other losses caused by the collision.

Washington follows a comparative-fault system. This means responsibility can potentially be divided among multiple people or entities rather than assigned entirely to one party.

For example, if evidence showed that more than one driver’s conduct contributed to a collision, fault could potentially be apportioned among those responsible.

Every case is different, and the amount of compensation available depends on the specific evidence, injuries and losses involved.

Why Serious I-90 Truck Accidents Require Careful Investigation

Interstate 90 through Snoqualmie Pass carries passenger vehicles and significant commercial traffic between Western and Eastern Washington.

A major semi-truck collision can shut down the interstate and require a substantial response involving Washington State Patrol, firefighters, tow operators, medical personnel and transportation crews.

When someone suffers serious injuries, the investigation should go beyond simply determining where the vehicles stopped.

Questions may include how fast the vehicles were traveling, whether a driver changed lanes, whether the truck was properly maintained, whether fatigue played a role and whether electronic information from the commercial vehicle provides additional evidence.

An attorney representing an injured person can investigate these issues separately from the law-enforcement investigation.

What to Do After a Serious Washington Truck Accident

People involved in a serious truck accident should make medical treatment their first priority.

When possible, injured people or their families should also preserve accident-related information, including medical records, photographs, witness contact information, insurance correspondence and documentation showing lost income or other financial losses.

It is also important to be cautious about providing detailed statements to an insurance company before understanding the nature and extent of the injuries and the circumstances surrounding the collision.

Speak With a Washington Truck Accident Attorney

A serious commercial-truck collision can create medical, financial and legal problems that continue long after the highway has reopened.

When substantial injuries are involved, determining who is responsible and obtaining the evidence needed to support a claim can require a detailed investigation.
