text: Most states in U.S. have prohibited cellphone use to a certain extent. In an article by the National Conference of State Legislatures, the author states "20 states... prohibit all drivers from using hand-held devices while driving. No state bans all cellphone use for all drivers, but 38 states and D.C. ban all cellphone use by novice or teen drivers, and 21 states and D.C. prohibit any cellphone use for school bus drivers. 48 states ban text messaging for all drivers." This demonstrates that states are taking action on the use of cellphones while driving.
