Within the jurisdictional limits of his or her appointing authority, any peace officer shall stop and detain any person found violating Section 442.05 without obtaining a warrant. When there is reasonable ground to believe that a violation of Section 442.05 has been committed and a test or tests of the person's blood, breath or urine is necessary, the peace officer shall take the person to an appropriate place for testing. If a person refuses to submit to a test after being warned as provided in Ohio R.C. 4506.17(C), or submits to a test that discloses the presence of a controlled substance or an alcohol concentration of four hundredths of one percent or more, the peace officer shall require that the person immediately surrender his or her commercial driver's license to the peace officer.
As used in this section, "jurisdictional limits" means the limits within which a peace officer may arrest and detain a person without a warrant under Ohio R.C. 2935.03, except that the Superintendent and the troopers of the State Highway Patrol may stop and detain, without warrant, any person who, in the presence of the Superintendent or any trooper, is engaged in a violation of any of the provisions of this chapter.
