The Maryland law prohibiting the use of a handheld phone or communication device while driving a car has been amended to assess more severe penalties in the event of a serious accident. If you are texting while driving and cause an accident which directly results in the death or serious bodily injury of another, it will be considered a misdemeanor. Conviction carries a possible sentence of up to one year in prison, or a fine of up to $5,000, or both.
For your own safety, as well as the safety of passengers and other drivers, you should never talk or text on a mobile phone while operating a moving vehicle. If you need to make a call or send a text, park in a safe place before doing so.
