St. Louis (KSDK) - Two men were rescued by St. Louis firefighters Tuesday morning after they did something not very smart, while driving along a walking path in a Smart Car.

Officials say the pair drove through an opening in the flood wall where Mullanphy Street meets the river. The car continued along a pedestrian trail until it could go no further.

The driver of the Smart Car tried to cut a U-Turn and the car ended up sliding and flipping into the river.

The two men were able to free themselves from the submerged car, and when firefighters arrived they helped them up a steep embankment to safety.

The two men were being treated, and questioned at the scene.
