Who is making these laws?
State legislators will continue to create laws that limit or ban hand-held cell phone usage while driving in their states.  New York was the first state to do so, in 2001, starting a trend that continues all across the nation.  California and Washington are the most recent states to ban cell phones while driving – both enacted laws in July 2008. 
What states currently have driving laws that ban hand-held phones?
New York, New Jersey, California, Connecticut, Washington and the District of Columbia each have enacted a state-wide ban on driving while talking on a handheld cellular phone.  Novice drivers are banned from using cell phones in 18 states, plus DC.
What are the fines if I am caught using a cellphone while driving?
The fines vary by state, from a starting fine of $20 in CA for the first time ($50 the 2nd), to $100 (plus fees) in NJ, DC, CT and NY, but in NY and NJ the fine goes to $250 the 2nd time.  So the possibilities of losing lots of money are great, if you rely on your phone while driving.
Are there states that are considering this legislation?
Several states (including Pennsylvania) currently have proposals in their legislatures to enact similar limitations or bans on cell phones while driving. The list above will get longer! 
What about text messaging?
While this is the most dangerous activity involving a cell phone, it is harder for legislators to define, and therefore to create a law addressing it.  There are 9 states that have outright bans on texting (6 that ban hand-held usage, plus AR, GA, NM), and more are likely to follow.  Since texting takes the most concentration, you should expect that this will be a hot topic with lawmakers in the near future.  (Friendly advice from EasyHandsFree – Don’t Text while Driving!)
Can cities and towns enact laws about driving with cell phones?
Six states (Illinois, Massachusetts, New Mexico, Michigan, Ohio and Pennsylvania) allow localities to ban cell phone use. Localities that have enacted restrictions on cell phone use include: Chicago, IL; Brookline, MA; Santa Fe, NM; Brooklyn, North Olmstead and Walton Hills, OH; and Conshohocken, Lebanon and West Conshohocken, PA.
With these being enforced, how does a hands-free system fit into the legal picture?
The good news is that hands-free systems will always be legal. Installing a high-quality, integrated hands-free system will allow you to conduct business and hold necessary conversations while keeping your hands on the wheel - improving your safety and keeping you legal.
