Bad News ... someone lost control of their car Tuesday night and smashed through the front gate of Bautista's gym in Florida.

Good News ... miraculously, no one was hurt!!!

It all went down outside of Dave's boutique gym in Tampa -- which looks like a house from the front -- where a black SUV crashed into the outside fence of the property in the middle of the night.

Bautista personally went down to the gym to check out the damage -- and admits he was in a "sh*tty mood" when he saw what happened.

But, the former WWE superstar says, "Thankfully no one was hurt."

Several Tampa Police Dept. officers also responded to the crash scene -- and Bautista says they couldn't have been nicer and more understanding.

So, what did Bautista do next? He took pics with everyone!!!
