Is it illegal to talk on a cell phone while driving in Indiana?

Indiana law bans the use of cellphones while driving for those under 18, and bans texting while driving for all drivers. The offense is a primary offense, which means you do not have to have another offense to be stopped. Ohio law bans the use of cellphones while driving for those under 18 and texting while driving is banned for all drivers. The offense is a primary one for those under 18 and a secondary offense for those 18 and older.
