Severe winds in Texas have wreaked havoc on big rigs … and some harrowing video got them toppling over!

Here’s the deal … wind gusts are blowing faster than 80 miles per hour in the Texas Panhandle … which is also kicking up a crap-ton of dust, making for awful visibility.

All this has been a wicked combination, as seen in wild vids like these — but the weather’s made it hell for truck drivers and motorists, too … causing several crashes — and creating an aftermath right out of “Mad Max.”

And it’s not just pictures … there has been some video of semis being blown around as though they weighed next to nothing.

It’s not clear how many people were injured in the crashes … but if that wasn’t bad enough, the high winds are also to blame for wildfires in Texas and Oklahoma, with several evacuations ordered.
