Lacey, WA (December 4, 2025) – Three people were injured on Thursday morning, December 4, after a serious multi-vehicle crash involving a car-hauling semi-truck and a school bus on northbound Interstate 5 near Martin Way East in Lacey.
The crash occurred around 7:29 in the morning near milepost 109 when a semi-truck carrying several vehicles jackknifed and blocked all northbound lanes. Investigators said the truck had been following a school bus too closely when the driver swerved to avoid a rear-end collision. The truck lost control, struck multiple vehicles, and caused a major traffic backup that stretched for miles.
Emergency crews from the Washington State Patrol and Lacey Fire Department arrived within minutes. Paramedics treated three injured victims at the scene before transporting them to nearby hospitals for further care. Officials confirmed that no children were on the school bus during the crash.
Troopers arrested the semi-truck driver for operating a commercial vehicle without a valid Commercial Driver’s License. Investigators documented the wreckage, collected debris, and interviewed witnesses before reopening all northbound lanes around 10 in the morning.
The Washington State Patrol continues to investigate this serious collision.
Multi-Vehicle Accidents in Washington
Multi-vehicle crashes are among the most dangerous and complex types of collisions on Washington highways. These chain-reaction crashes often occur within seconds, leaving drivers with little time to respond. Busy routes like Interstate 5 in Thurston County are particularly vulnerable, especially when large trucks are involved.
The injuries caused by these accidents can be severe and life-changing. Victims often suffer broken bones, spinal injuries, or brain trauma that require long-term medical care. The brain is a soft and delicate organ, and even a minor jolt can lead to serious complications. A sudden impact can disrupt memory, balance, and mood, with symptoms sometimes appearing hours or days later. Prompt medical evaluation helps identify these hidden injuries early and prevent long-term effects.
If you sustained injuries in a car accident, you may be entitled to compensation for:
- Medical expenses and hospitalization
- Rehabilitation and long-term therapy
- Lost wages or reduced earning ability
- Pain, suffering, and emotional distress
- Vehicle repairs or replacement
When multiple vehicles are involved, determining fault can be complex. With several drivers and insurance companies disputing responsibility, victims often face long delays in receiving fair compensation. That’s why it’s essential to work with an experienced personal injury attorney who understands car accidents. A skilled legal team can gather evidence, investigate the crash, and handle insurance negotiations.
