Ohio Rev. Code § 4506.23
Within the jurisdictional limits of the appointing authority, any peace officer shall stop and detain any person found violating section 4506.15 of the Revised Code, without obtaining a warrant. When there is reasonable ground to believe that a violation of section 4506.15 of the Revised Code has been committed and a test or tests of the person's whole blood, blood plasma or blood serum, 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 division (C) of section 4506.17 of the Revised Code or submits to a test that discloses the presence of a controlled substance or an alcohol concentration of four-hundredths of one per cent or more by whole blood or breath, an alcohol concentration of forty-eight-thousandths of one per cent or more by blood serum or blood plasma, or an alcohol concentration of fifty-six-thousandths of one per cent or more by urine, the peace officer shall require that the person immediately surrender the person's 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 section 2935.03 of the Revised Code, 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 the violation of this chapter.
