An unintended big splash has left a vehicle in a private swimming pool in South Texas.

Investigators in San Antonio are trying to determine what caused a woman to lose control of her car Wednesday night. The vehicle crashed through a rock wall and a privacy fence before landing in the backyard pool.

The driver was transported to a hospital to be checked out, as a precaution. Her name wasn't immediately released.

Homeowner Nelda Zuniga says maybe the car needed a good wash.
