Define "aggressive driving" under Massachusetts law.

The definition of "aggressive driving" under Massachusetts law highlights the significance of dangerous driving behavior that poses a threat to the safety of others. This encompasses actions such as tailgating, weaving through traffic, excessive speeding, and other reckless maneuvers that increase the risk of a collision or harm to other road users.

The emphasis on endangering others is crucial because it shifts the focus from mere annoyance or frustration on the road, which could be subjective, to measurable behaviors that are distinctly hazardous. In the context of enforcing motor vehicle laws, identifying aggressive driving requires recognizing specific actions that violate traffic safety norms, rather than relying solely on the feelings or perceptions of those involved in a traffic situation.

This understanding stands in contrast to the other options, which either too broadly define aggressive driving by focusing on emotional responses and subjective experiences, or limit it to specific behaviors like speeding without addressing the overall risk to public safety that characterizes aggressive driving. Thus, the correct choice encapsulates the comprehensive nature of aggressive driving as it pertains to endangering others on the roadway.
