Two cars were towed for trying to start a sideshow on Interstate 880 in Oakland over the weekend.
Sideshows are becoming a dangerous trend in the Bay Area.
And on Monday night, we are seeing the benefits of police stepping up their patrols.
Officers in Oakland were able to stop a sideshow before it started.
Oakland police tweeted out pictures of the cars being loaded onto tow trucks.
The drivers will not be able to get their cars back for 30 days.
It is not clear if the drivers were arrested.
