JUNEAU, Wis. (AP) -- The summer months bring new hazards to Wisconsin highways from farm tractors using the roadways to travel from field to field.

Dodge County sheriff's Capt. Molly Soblewski says rules of the road still generally apply when encountering a tractor. You can't pass in a no-passing zone. And, even when passing, motorists might not have a full lane to maneuver around the tractor and farm equipment.

Soblewski says a motorist might be driving at 55 mph, but a tractor on the other side of a hill might be going 5 or 10 mph. The Beaver Dam Daily Citizen says tractors don't have to be licensed if they're used for farm work and are traveling between farms.

Last Tuesday, a motorcyclist was killed in Grant County when he collided with a tractor pulling a haybine at an intersection in Glen Haven Township.
