Key legal question
Whether using the emergency lane to pass slower traffic is a prohibited right-side overtake and how the offense should be classified administratively.
Extracted holding
The maneuver was a prohibited right-side overtake and not merely a minor lapse; it constituted a moderately serious traffic offense.
Extracted reasoning
The emergency lane is not a traffic lane. The respondent used it to gain ground past queued vehicles without any established exceptional authorization. The risk to traffic safety was real and could materialize at any time, so the fault was not benign.
