No, you should not let your manager talk you into "just handling it" through auto insurance if you were working when the crash happened.

That pressure is about the employer's interests, not yours.

And if you hold a CDL, this gets touchy fast. Your driving record, your DAC report, and your ability to get hired again can all be affected by how the crash is documented. So the first job is not arguing with the adjuster. It's locking down evidence before it disappears.

Start with the part nobody photographs

SI joint dysfunction after a rear-end crash usually doesn't look dramatic at the scene.

No bone sticking out. No big windshield spiderweb. Sometimes you walk away thinking your lower back is just tight.

Then 24 to 72 hours later, the pain settles deep near one side of the low back or buttock, starts shooting into the hip, and sitting or climbing in and out of a vehicle becomes miserable. On I-70 near Jefferson City, with all the stop-and-go around the Missouri River bridge, Highway 54 interchange, and truck traffic pushing through central Missouri, rear-end wrecks happen exactly this way.

Photograph what people usually miss:

• the rear bumper and hitch area, even if damage looks "minor"
• the inside of the vehicle: twisted seatback, broken headrest posts, items thrown forward, floor mats shifted
• your body over several days: bruising, swelling, uneven posture, any limp
• the exact crash area, lane markings, skid marks, traffic cameras nearby, mile markers, weather, and road conditions
• your work gear in the car: badge, uniform, schedule printout, delivery sheet, or text showing you were on the clock
• the odometer and dashboard if the vehicle had warnings after impact

That last part matters because employers love to blur the line and act like you were "just commuting" when you were actually running an errand, transferring stock, making a bank drop, or driving between store locations.

Save proof before your phone eats it

Your phone is evidence, and it's also a shredder if you do nothing.

Take screenshots of call logs, texts from your manager, dispatch messages, clock-in records, schedule apps, GPS history, and any message where somebody says not to report it through workers' comp. Save them somewhere outside the phone too. Email them to yourself. Upload them to cloud storage. Back them up.

If there were hands-free calls right before or after the crash, preserve that too. Phone carriers don't hold detailed records forever, and some app-based communications disappear even faster.

Don't edit videos. Don't trim them. Keep the original file with the metadata.

If your store has a fleet app, telematics, or route-tracking system, write down the system name now. Same for any in-store scheduler that proves you were working.

Witnesses vanish quicker than pain shows up

The witness who stopped on the shoulder near US-63 and said, "Yeah, I saw the whole thing," may be useless by next week if you didn't get the name and number.

Same with the guy in the pickup behind you. Same with the employee from the QuikTrip or gas station where you pulled off after the wreck.

Get full names, phone numbers, and where they were positioned. Then write a short note for yourself: what they said, what lane they were in, whether they mentioned brake lights, speed, traffic slowdown, or distraction. Missouri is a pure comparative fault state. That means the other side will happily argue you stopped too fast, drifted, or contributed somehow, even in a rear-end crash.

Dashcam footage is not automatically waiting for you

If your vehicle had a dashcam, secure that file immediately.

If the other vehicle was a company truck, there may be forward-facing video, inward-facing video, telematics, and hard-braking data. The bad news: companies overwrite that stuff all the time. Sometimes in days.

If MODOT cameras caught traffic flow near the scene, don't assume the footage sticks around.

You do not need to know every legal trick here. You do need to act like electronic evidence is on a countdown clock, because it is.

Get the crash report, then read it like your job depends on it

In Jefferson City, the investigating agency might be Jefferson City Police, Cole County deputies, or the Missouri State Highway Patrol if it happened on I-70. Get the report as soon as it's available and read every line.

Not skim. Read.

If it says you were not working when you were, that matters. If it lists the location wrong, that matters. If it leaves out a witness, that matters. If the officer noted "no injury" because your SI pain had not fully kicked in yet, that does not mean you weren't hurt. It means the report captured one moment, not the whole medical picture.

The employer pressure is part of the evidence too

If your manager says filing workers' comp will "make things harder," "hurt the store," or "mess with insurance," save that communication.

Because here's what most people don't realize: when you were doing job duties, workers' comp may be in play even if another driver caused the crash. Missouri is an at-fault auto insurance state, but that does not erase a work-related injury claim. One system doesn't cancel the other just because your boss wishes it would.

And with an SI joint problem, delay is poison. The insurer will say your pain came from stocking shelves, an old back issue, your weekend yard work, or getting in and out of a truck. The longer you wait, the uglier that argument gets.

So preserve the timeline now: crash photos, report number, names, texts, work assignment, symptoms day by day, and every medical visit from the first complaint forward.

That paper trail is what keeps a rear-end collision from being rewritten as "just soreness" and a work injury from being buried because a manager didn't want the claim on the books.
