Maryland vehicle law makes it illegal for all drivers to text while driving, regardless of age or learner's permit status.
Step-by-step explanation:
According to Maryland vehicle law, it is illegal to text while driving for all drivers. This law is not limited to any particular age group or driving status. It encompasses everyone from new drivers with a learner's permit to those over the age of 21. Texting while driving is a significant safety concern, as it distracts the driver and can significantly increase the risk of accidents.
