Which action may result in criminal charges for a Massachusetts driver?

Answer: B — Refusing to sign a traffic citation

The action that may result in criminal charges for a Massachusetts driver is refusing to sign a traffic citation. When a police officer issues a citation, signing it is not an admission of guilt but rather a promise to appear in court or pay the fine. If a driver refuses to sign, it can lead to further complications, including potential criminal charges, as this refusal is often interpreted as non-compliance with lawful authority. In contrast, refusing to wear a seatbelt, while it may carry fines, does not typically result in criminal charges. Refusing to pay a fine can lead to additional fines or penalties but does not automatically result in criminal charges either. Similarly, not buckling in a minor can lead to fines or penalties but is not generally classified as a criminal offense in Massachusetts unless there are aggravating factors involved.
