General Discussion What is this truck carrying?

It doesn’t appear to have a license plate either 🤔

If you're real curious, the Emergency Response Guidebook is available for free as an app or pdf and contains info on all of the UN numbers. More often than not when we're driving somewhere I ask my wife to pull it up and look up a UN number.

What’s the wildest one you’ve seen?

Class 1 (explosives), 4 (flammable solids), and 8 (corrosive) transported together. I forget what they were specifically but regs prohibit them being transported in the same vehicle. I called it in to highway patrol.

Ever seen a Walmart truck? Those things are fucking bombs on wheels. They will load it up with ammo, fertilizer, lithium batteries, camping propane canisters, tires, clothing, etc. All of it is under the legal declaration weight of each product. None of it needing markings due to quantity. And send it down the highway.

Oh yeah, and they know full well what they're doing.

Yeah. They do. Absolutely insane to think about.

1.4s, 4.1s and 8s CAN be transported together. The 4.1s and 8s just have to be segregated.

However, if it's anything other than those 3 SPECIFIC hazard classes, then no. They can not be transported together. 4.2s and 4.3s can't be with corrosives and 1.1-3 and 1.5 can't be transported with anything else.

Literally on the way to my hazmat tech class I saw a trailer filled with gel explosives. Probably on the way to a quarry so not that weird, but it was the first time I've seen explosives not on a military convoy.
