A 2-minute lesson from the Oklahoma course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
In rural Oklahoma you'll meet tractors, combines and other farm equipment moving between fields on state highways. They can be very large, may use more than one lane, and usually travel under 25 mph. Expect the unexpected.
Know the rule
Be alert for slow-moving vehicles, especially in rural areas. Farm equipment may use more than one traffic lane.
Used on agricultural equipment, highway and roadside construction equipment, and highway maintenance equipment traveling on public highways at 25 mph or less.
Coming over the top of a hill at 65 mph to find a large, slow tractor in front of you is frightening and dangerous. Be prepared to protect yourself and your passengers.
In some areas you may share the road with animal-drawn vehicles. They have the same rights to use the road as a motor vehicle and must follow the same rules of the road.
Cresting a hill on a two-lane state highway, you see a combine displaying the Slow Moving Vehicle emblem ahead doing about 20 mph. Slow down right away and stay back. Pass only where it's legal and you can see enough clear road.
