Patrol spokeswoman Kim Montes said Asia Walker, 30, was at the wheel Friday when her car hit the house in Daytona Beach, WESH-TV, Orlando, Fla., reported Monday.
Walker was injured by falling debris and taken to Halifax Medical Center to be checked out; her boyfriend, Charles Phillips, was not hurt, the spokeswoman said.
"She told the investigating trooper that her and the boyfriend were getting a little amorous and the trooper suspects that's probably why she lost control of the vehicle," Montes said.
Police said the vehicle went all the way through the unoccupied house, causing major damage.
Walker was charged with careless driving.
