Farm equipment legal on interstates under Idaho law

After a tractor traveling on I-15 near Blackfoot led to a crash involving a semi and a car Friday, many have asked if it’s even legal for tractors and other farm equipment to travel on the interstate.

It turns out, it is.

Idaho Statute Title 49, Chapter 6 outlines few restrictions for slow-moving vehicles. Among them, they must have lights if traveling after dark, obey the maximum posted speed limit and bear a sign identifying them as slow-moving.

But Bannock County Sheriff Lorin Nielsen said there’s no minimum speed limit on Idaho’s roads.

“It’s not regulated other than how fast you can go, not how slow you can go,” said Nielsen.

Friday’s crash occurred when a semi was attempting to avoid a tractor traveling in the right lane of I-15. It struck a Chevy Cobalt and knocked it into the median.
