Rancho Cucamonga Courthouse — court & DMV details
Why your case is here
The Rancho Cucamonga courthouse at 8303 Haven Avenue is the designated criminal court for the West Valley, the western, freeway-laced end of San Bernardino County. DUIs from Rancho Cucamonga, Ontario, Upland, Montclair, Chino, Chino Hills, Fontana, Rialto, and Bloomington are heard here. Notably, although Fontana has its own courthouse, its criminal cases route to Rancho Cucamonga. DUI enforcement here is heavy on the I-15, I-210, and I-10 and around Ontario International Airport.
The 10-day DMV deadline
A West Valley DUI means two cases at once: the criminal case at Rancho Cucamonga and the DMV's separate case against your driving privilege, with a 10-day deadline to request a hearing. How the DMV hearing works →
