Starting Jan. 1, 2012, police in California can no longer impound vehicles from DUI checkpoints when the driver's only offense is driving without a license. The impounds have been controversial where critics say they are used to drive out illegal immigrants. The American Civil Liberties Union has questioned how much Escondido is making from illegal immigrants whose cars are impounded because they do not have drivers licenses. (AP Photo/Lenny Ignelzi)
