Okla. Stat. tit. 70, § 70-19-124: Student drivers as passengers

A. Except as provided in subsection B of this section, each

commercial driver training school as defined in Section 801 of Title

47 of the Oklahoma Statutes or school district providing driver

education training or classes shall only allow a student driver

receiving instruction to operate the motor vehicle when there are no

other student drivers in the motor vehicle as passengers.

B. The parent or legal guardian of a student driver may sign a

waiver which would allow the student driver to ride as a passenger

in a motor vehicle that is being operated by another student driver.

The waiver shall be on a separate form and include the following

statement: "I understand if my child is a passenger in a motor

vehicle operated by a student driver, there is a risk of death,

serious injury, or collision." If the parent or legal guardian

refuses to sign the waiver, the commercial driver training school or

school district shall not refuse to admit the student driver.

C. As used in this section, "student driver" shall mean any

person receiving driver education training who is younger than

eighteen (18) years of age.
