These signs are popping up in California. On the 15 Freeway between Vegas and Los Angeles for example as well as along I40.

The Prank California highway signs 'welcome' felons, illegal immigrants and MS-13 and explain 'Democrats need the votes'.

According to Fox News California Department of Transportation (Caltrans) spokesman Mark Dinger said one of the signs was taken down yesterday and a crew has been dispatched today to remove another.

“For safety reasons, Caltrans does not permit any unauthorized signs in the state right of way," the agency said in a statement. "If we haven’t done so already, Caltrans crews will take steps to remove them.”

California became a “sanctuary state” on Monday after a bill Democratic Gov. Jerry Brown signed into law in October officially took effect.
