"Was your knee already bad before the crash?" That is the adjuster question coming, and your answer matters because Washington will pay for an aggravation of a pre-existing condition if the road-work crash made it materially worse.

Yes, it can absolutely be worth pursuing in Vancouver, especially with a shattered kneecap, torn ligaments, or a major loss of mobility after a lane-shift or flagger-zone collision. Washington has no cap on pain-and-suffering damages, so a strong claim is not limited just because your knee was imperfect before.

To prove it, lock down this evidence fast:

• Pre-crash records showing your baseline: old orthopedic notes, prior MRI/X-ray reports, physical therapy records, and how active you were before the wreck.
• Post-crash records from the ER, urgent care, orthopedist, and imaging that show what changed after the collision.
• Scene evidence from the first 24 to 48 hours: photos of cones, lane shifts, skid marks, heavy equipment, your vehicle, and any missing or confusing work-zone signs.
• Witness names and the road contractor or flagging company name if the crash happened in a construction zone near Vancouver.
• The police report from Vancouver Police, Clark County Sheriff, or Washington State Patrol, depending on where it happened.
• Wage-loss proof if you missed work or can't kneel, climb, drive, or stand like before.

The mistakes that kill value are predictable. Saying "I'm fine" at the scene. Waiting a week to get checked. Posting gym photos or vacation pictures. Letting the insurer record a statement before you know your diagnosis. Failing to mention your new symptoms clearly: swelling, instability, locking, inability to bear weight, missed shifts, trouble with stairs.

Washington's deadline for most injury lawsuits is 3 years. If a city or state agency helped create the hazard, extra notice rules can apply, so do not sit on it.
