(c) (1) Any person under the age of 21 years 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 was 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.
