We are referring to it as the "new" law just to avoid confusion. We all know it's been around for a few years, and is just now becoming truly enforceable, although there are new elements with the teen restrictions.
RCW 46.61.667 is the law concerning talking on a cell phone and driving which is $124 fine.
RCW 46.61.668 is the law concerning texting while driving which is $124 fine.
RCW 46.20.055 is the law concerning violations of an instruction permit which is a $124 fine.
RCW 46.20.075 is the law concerning violations of an IDL which is a $124 fine.
The HB6345 makes it a primary offense for a person with an instruction permit or Intermediate Drivers License to be talking on a cell phone. The rest of the statutes remain the same, which are secondary violations.
Officers will be stopping drivers for talking or texting under those laws no matter what their ages are. Then once stopped and they hand over an instruction permit or IDL, they could be cited in addition to the cell/text law for violating their instruction permit or IDL.
