Although Oklahoma does not have a law specifically prohibiting use of handheld cell phonesdrivers can be cited under the 2010 law against "inattentive" driving, which states that drivers must give their full time and attention to operating the motor vehicle (OK Stat. Tit. 47 Sec. 11-901c),
Law enforcement officers may stop drivers whose inattentiveness is deemed a safety hazard. They may also cite drivers under this law who have had accidents or who have violated other traffic laws and are suspected of talking on a cell phone or texting when the incident occurred.
Note that some municipalities have passed legislation that allows its officers to stop drivers for texting and other distractions while a vehicle is in motion that classify them as being inattentive under the state law.
