I did actually have that happen. Never did figure out why
It's a combination of physics and geometry when it does that. You can be on an incline, or level surface and make it do the bucking bronco dance if the conditions are set up just right---speed, weight, angle of steer tires, and measured distance from drives to the trailer axles. I'm not going to put you to sleep explaining the theory and formula.
Quickest fix is to immediately get off the fuel, and purposely apply the brakes. Change one part of the ingredients above, and it should go more easily.
Next time that happens, try to get a POV video of yourself getting slammed around, please.

I'm thinking my company needs to install drivecams just so I could have seen how foolish I looked getting thrown all over
I had an incident once where I hooked up to my load out in the shippers yard on fairly smooth, level gravel (paper rolls) and when I started to drive straight with it the truck bucked hard enough to trigger an event recording on my Qualcomm. Still dont know what caused it. Just a single giant buck. Strangeness.

We’re your tandems locked? That will scare the crap out of you. Don’t ask how I know.

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

I'm not really sure, but I think they were locked, it happened back in December. Though when i was with trainer i was coming to a stop at a red light and heard and felt a loud crashing. I thought i was rear-ended. He sat there for a minute and started laughing, I pulled over after I got through the intersection. Sure enough he forgot to lock the tandems when he hooked up to the trailer which is why it was funny to him, scared the poo out of me though.

Yep. I forgot mine once, and another time they broke loose in a panic stop. An experienced driver told me if the spring is weak that could happen. I knew they were locked when I loaded, I was convinced someone pulled them at a truck stop I took my break at.

When a violation by either a driver or company is confirmed, an out-of-service order removes either the driver or the vehicle from the roadway until the violation is corrected.
Better pay as much attention to those tandems being locked as you do the fifth wheel being locked. I've seen tandems break out the back end of the trailer and leave a big mess and a big ticket fine for the x-driver more than a few times.

Yep. I check mine every time now. That’s how I know it was locked the second time. The first time was enough to scare the crap out of me.

Last Sunday I took a load to one of our stores in Independence (KC) MO. I've been there before twice without issues but the strangest thing happened this time. As I was pulling in the truck began to buck to the point I was sitting low in the seat and hit my head on the ceiling. My phone was also resting on the dash and that got thrown to the floor.
I turned left into the store and needed to hook an immediate right to hit the dock next to the big blue compactor up top. Tandems were all the way forward due to previous store being pretty tight. All I can think is maybe with the angle I came in mixed with with tandems all the way up it lifted drives off the ground just enough that I lost traction? Anything like that ever happen to anybody? Truck was great before, and after this happened.
Of course the warehouse stacked the front pallet for this store like crap and had a pallet tip over which ended up breaking some eggs and breaking the strap I had in place. It was one of the most frustrating weeks I've had with this job, as I'd also had a pallet tip over at first store of the day(Liberty MO) and the day prior at Lee Summit due to how the warehouse stacked pallets with product partially off the pallet causing it to fall when I pull it off. Always seems I have problems when I go to KC, think I'll steer clear for a bit even though it could happen anywhere.

TWIC:
Transportation Worker Identification Credential
Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.
Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.
