If someone hits my vehicle and that person's insurance company writes me a check and I keep the money rather than get my vehicle repaired, is that insurance fraud?

The insurance company didn’t total my truck but issued a me a check that, in my opinion, is for about what the truck is worth considering the oil leak and the rust damage to the frame. I am considering just pocketing the check and junking the truck. I was paid essentially what it was worth, I have another vehicle, and keeping it costs me in insurance payments.
