§ 23154 Driving Under the Influence of Alcohol While on Probation for Prior DUI

23154.

(a) It is unlawful for a person who is on probation for a
violation of Section 23152 or 23153 to operate a motor vehicle at any
time with a blood-alcohol concentration of 0.01 percent or greater,
as measured by a preliminary alcohol screening test or other chemical
test.

(b) A person may be found to be in violation of subdivision (a) if
the person was, at the time of driving, on probation for a violation
of Section 23152 or 23153, and the trier of fact finds that the
person had consumed an alcoholic beverage and was driving a vehicle
with a blood-alcohol concentration of 0.01 percent or greater, as
measured by a preliminary alcohol screening test or other chemical
test.

(c) (1) A person who is on probation for a violation of Section
23152 or 23153 who drives a motor vehicle is deemed to have given his
or her consent to a preliminary alcohol screening test or other
chemical test for the purpose of determining the presence of alcohol
in the person, if lawfully detained for an alleged violation of
subdivision (a).

(2) The testing shall be incidental to a lawful detention and
administered at the direction of a peace officer having reasonable
cause to believe the person is driving a motor vehicle in violation
of subdivision (a).

(3) The person shall be told that his or her failure to submit to,
or the failure to complete, a preliminary alcohol screening test or
other chemical test as requested will result in the suspension or
revocation of the person's privilege to operate a motor vehicle for a
period of one year to three years, as provided in Section 13353.1.
