What constitutes a "serious injury" under Massachusetts driving regulations?

In Massachusetts driving regulations, a "serious injury" is defined as an injury that necessitates immediate medical attention. This definition highlights the severity of the injury, indicating that it poses a significant risk to the individual's health and often requires urgent care to address the medical needs resulting from an accident.

While injuries requiring a hospital stay or causing minor pain might also indicate a need for medical intervention, they do not specifically capture the urgency and seriousness recognized in driving regulations. Similarly, injuries described as causing temporary discomfort do not meet the threshold for serious injury, as they are generally not life-threatening and may not need immediate medical attention. Thus, the requirement for urgent care makes the first option the correct characterization of what constitutes a serious injury in the context of Massachusetts driving laws.
