Is there a copy of the specific law that I can read somewhere?
TITLE 21 § 1280.1.C.6
A handgun carried in a motor vehicle pursuant to a valid handgun license authorized by the Oklahoma
Self-Defense Act onto property set aside by a public or private elementary or secondary school for the
use or parking of any vehicle; provided, however, said handgun shall be stored and hidden from view in a
locked motor vehicle when the motor vehicle is left unattended on school property.
