Kim Zolciak -- Garage Fire Emergency

A fire truck raced to the home of "Real Housewives of Atlanta" star Kim Zolciak this morning after an ATV in her garage went up in flames -- but thankfully, no one was hurt.

A rep for the Roswell Fire Department in Georgia tells TMZ, they received a call about a garage fire at 9:35 AM and dispatched a truck to the scene.

We're told the 4-wheeler fire was successfully extinguished and did not spread to other areas of the home. Everyone in the house is fine.

Kim just tweeted, "Shout out to Roswell Fire Dept for their quick response this morning!"
