One of my old GF's got a ticket for pulling onto the shoulder of the freeway to talk on her cellphone, she didnt want to talk while driving, and had to make a call. The highway patrol gave her a $110 ticket, luckily the judge dismissed the ticket when we fought it.
Personaly, i think the states should do as englad has done and ban cell phones when driving. Cell phone users cause just as may traffic accidents as drunk drivers do now!
