On a two-lane highway, you come up behind a farm tractor that shows an orange slow-moving vehicle triangle. A solid yellow line is on your side of the center line. What should you do?
A follows a farm tractor displaying an orange slow-moving-vehicle triangle. The center line beside A is solid yellow.
Correct answer: Slow down, stay back, and pass on the left when it is legal and clear
Why
Farm tractors and other slow vehicles often travel at 25 mph or less, so you close the gap on them very fast. Spot them early so that you can slow down smoothly; a sudden stop can cause a crash behind you. In rural South Dakota, farm machinery also moves across the road and along state highways, so watch for it.
