As of the moment of this writing, Maryland is less than five hours away from joining the states where the non hands-free usage of a cell phone is illegal. As of midnight tonight, driving while using a cell phone in a manner which utilizes your hands (and yes, between the cocked head and shoulder counts) is illegal.
That said, you can't get pulled over for it. However, it is a secondary offense, which means that if a cop pulls you over for something else, if he/she also saw you using the phone in a non hands-free manner, you'll get a ticket for that too.
Longtime readers of this blog know how I feel about this. It's a good idea. I don't know how many ignorami I see not watching the road, but rather way too obsessed with talking with their whatever on the damn cell phone. I know some comments to my prior post on this topic challenged me on this, but I can't help but think that hands-free use of a cell phone is safer.
Additionally, as of midnight it will be illegal to do any texting-related activities while driving a car. You can no longer read as well as write messages.
