Saddlebagged

When your car is stuck due to a material pushing on the bottom preventing the wheels from getting traction.

A wedge pressing against the under carriage of a car.
Imagine a teeter totter only with a car for the board and seats.

A snow plow came past the drive way making a mound of snow. I tried to ram it but my car got staddlebagged. I tried to jump the curb now I'm saddlebagged.
