“ASK A TROOPER” by Sgt. Jesse Grabow of the Minnesota State Patrol
Question: What is the law (if there is one) concerning the farmers irrigation system spraying water on the highway and having to drive through it. To me it is a hazard for automobiles (hydroplaning etc.) and extremely dangerous for motorcycles.
Answer: This is a good one; as I received three similar questions on this very topic this week. Through my research, I was unable to locate any law or statute that specifically states that it is illegal for an irrigation system to spray water on a highway; however, I did find this in Minnesota State Statute 160.2715:
(1) obstruct any highway or deposit snow or ice thereon;
(2) plow or perform any other detrimental operation within the road right-of-way
Violation of this statute is a misdemeanor. It is my opinion that if enough water was deposited onto the highway, this statute may apply. “Obstruct any highway” does not only mean “to block” but “to hinder from passage” and “impede.” As for “detrimental” meaning “obviously harmful,” if the water standing on the road caused more than a wet roadway - enough to hydroplane and thus cause a crash - this too would be an issue.
I would encourage anyone that observes a safety issue on a roadway to report is as quickly as possible so the proper road authority can address it as soon as possible.
