The state of Washington bans the use of hand-held cellphones while driving.
Hands-free cellphone use is allowed. But enforcement of the hand-held ban in Washington was strengthened with a law that went into effect in June in which drivers can be pulled over if they are seen speaking on a hand-held device.
Pulling over the side of the road to make a call is also illegal.
Drivers under the age of 18 may not use any kind of mobile device while driving. Texting is also banned for all drivers.
