DRIVING IN CALIFORNIA
Nonresident persons do not need to get a California driver license. The state
recognizes out of state and foreign driver licenses for nonresident individuals.
Section 12502 and 12505 (reported below) of the vehicle code defines
nonresident based on the individual's state of domicile which is defined as: "the
state where a person has his or her true, fixed, and permanent home and
principal residence and to which he or she has manifested the intention of
returning whenever he or she is absent."
Vehicle Code
Section 12502
(a) The following persons may operate a motor vehicle in this state without
obtaining a driver license under this code:
(1) A nonresident over the age of 18 years having in his or her immediate
possession a valid driver license issued by a foreign jurisdiction of which
he or she is a resident, except as provided in Section 12505.
Section 12505
(a) (1) For purposes of this division only and notwithstanding Section 516,
residency shall be determined as a person’s state of domicile. "State of domicile"
means the state where a person has his or her true, fixed, and permanent home
and principal residence and to which he or she has manifested the intention of
returning whenever he or she is absent.
Prima facie evidence of residency for driver licensing purposes includes,
but is not limited to, the following:
(A) Address where registered to vote.
(B) Payment of resident tuition at a public institution of higher education.
(C) Filing a homeowner’s property tax exemption.
(D) Other acts, occurrences, or events that indicate presence in the state
is more than temporary or transient.
(b) The presumption of residency in this state may be rebutted by satisfactory
evidence that the licensee’s primary residence is in another state.

Grounds Requiring Refusal of License
Section 12805 The department shall not issue a driver license to, or renew a
driver license of, any person:
(f) Who holds a valid driver license issued by a foreign jurisdiction unless the
license has been surrendered to the department, or is lost or destroyed.

If you are in California with a J-1 visa and you drive without a California driver
license, it could be a good idea to keep a printout of the above information in
your vehicle at all times. Foreign drivers should also keep with them a copy of
their visa. Hopefully, these documents might help you explain why you do not
have a California driver license in the event the police question you.
International Driving Permits
The State of California does not recognize an International Driving Permit (IDP)
as a valid driver license. California does recognize a valid driver license that is
issued by a foreign jurisdiction (country, state, territory) of which the license
holder is a resident.
The IDP is only a translation of information contained on a person's foreign driver
license and is not required to operate a motor vehicle in California. Citations
issued to a person in California who has an IDP, but does not have a California
driver license will be placed on the Department of Motor Vehicles database.
The IDP is also called an International Driver License, International License, etc.
