A commercial vehicle accident happens fast, and the minutes right after can feel like a blur — especially on a busy Seattle-area roadway with traffic backing up around you. What you do in that first hour, though, can shape both your health and your ability to recover compensation later. Whether you were hit by a semi-truck, a rideshare driver, or a delivery van, here’s a practical, step-by-step guide to what to do immediately after the crash.

1. Check for Injuries and Get to Safety
Before anything else, check yourself and your passengers for injuries. If you’re able to move safely and your vehicle is drivable, get out of active traffic lanes — onto the shoulder or a nearby side street — to reduce the risk of a secondary collision. Turn on your hazard lights. If you’re on a freeway like I-5 or I-90 during rush hour, staying inside a stopped vehicle in a live lane is genuinely dangerous, so only move it if you can do so safely.
If anyone is seriously hurt or a vehicle can’t be moved, stay where you are and wait for help rather than risking further injury.
2. Call 911
Call 911 immediately, even if the damage looks minor. Washington State Patrol or local police will need to respond, especially on state highways and interstates, and a delivery driver, rideshare vehicle, or commercial truck involved in a collision typically triggers additional reporting requirements. An official police report becomes an important piece of evidence, documenting the time, location, parties involved, and initial observations about how the crash happened.
When officers arrive, answer their questions honestly but stick to the facts. Avoid speculating about fault or apologizing reflexively — a simple “I’m sorry” can later be misconstrued as an admission of fault, even when it’s just a natural human reaction to a stressful moment.
3. Get Medical Attention — Even If You Feel Fine
Adrenaline can mask pain for hours or even days after a crash. Injuries common in commercial vehicle accidents — whiplash, concussions, soft tissue damage, internal injuries — don’t always announce themselves right away. If paramedics are on scene, let them evaluate you. If you decline transport at the scene, still see a doctor or visit an emergency room, such as Harborview Medical Center or another Seattle-area hospital, within the following day or two.
This isn’t just about your health, though that’s the most important reason. A documented, timely medical evaluation also creates a paper trail connecting your injuries to the accident — something an insurance adjuster will scrutinize closely if you wait too long.

4. Document Everything at the Scene
If you’re physically able, gather as much information as possible before you leave the scene. Details fade quickly, and commercial vehicles often have their own investigators who move fast — sometimes within hours — to gather evidence favorable to the company.
- Take photos of all vehicles involved, from multiple angles, including license plates and any visible damage
- Photograph the road conditions, traffic signals, skid marks, and debris
- Get the truck, rideshare, or delivery driver’s name, license number, and insurance information
- Note the company name and any identifying numbers on the vehicle (DOT number, fleet number, rideshare platform)
- Collect contact information from any witnesses nearby
- Write down (or record a voice memo of) your own recollection of what happened while it’s fresh
5. Be Careful What You Say and Sign
Commercial trucking companies, delivery services, and rideshare platforms typically have insurance representatives who may contact you quickly after a crash — sometimes within a day. They may seem friendly and helpful, but their job is to minimize what the company pays out. Avoid giving a recorded statement, signing any documents, or accepting a settlement offer before speaking with an attorney. Once you sign a release, you generally can’t go back and ask for more, even if your injuries turn out to be more serious than they first appeared.

6. Preserve Evidence Before It Disappears
Commercial vehicles carry data that ordinary cars don’t — electronic logging device records, GPS data, onboard camera footage, and maintenance logs. This evidence can be routinely overwritten or discarded within days or weeks unless someone formally demands it be preserved. An attorney can send a preservation letter to the trucking company, delivery service, or rideshare platform right away, which is one of the most time-sensitive steps in these cases.
7. Contact an Attorney Early
Commercial vehicle accidents are almost always more complicated than a typical two-car collision. There may be multiple liable parties — the driver, the company that employs them, a maintenance contractor, even a vehicle manufacturer — and multiple insurance policies involved. Reaching out to an attorney early, before evidence disappears and before you’ve said anything to an insurance adjuster, puts you in a much stronger position from the start.
The moments after a commercial vehicle accident are overwhelming, but taking these steps — prioritizing safety, documenting the scene, seeking medical care, and getting knowledgeable legal guidance early — protects both your health and your rights. If you or someone you love has been involved in a truck, rideshare, or delivery accident in the Seattle area, you don’t have to sort through the next steps alone.
