Two government snowplows are working in a diagonal formation with their warning lights on. May you pass the formation?
Two working government snowplows occupy both lanes in diagonal formation with warning lights on. No following learner vehicle appears.
Correct answer: No. Stay behind and give the working plows space.
Why
Do not pass an authorized government snowplow displaying warning lights and working in a diagonal, or echelon, formation with another plow. Snow clouds and ridges between the plows can hide hazards. Stay back and be patient.
