A large, unexpected speed bump appears on a highway.

The video shows a series of cars driving on a highway. A large, rough-looking speed bump is placed across the road. A cannon is visible on the side of the road. First, a black car drives over the speed bump and is fine. Then, a taxi drives over it and its front bumper breaks off. Next, a yellow car drives over it and flips upside down, crashing. A police car then drives over it and jumps over it, landing safely. Finally, a fire truck drives over it and jumps over it, landing safely. A school bus is shown in the distance at the end.
