A slow-moving vehicle, such as a tractor or other piece of large farm machinery is unable to travel at highway speed. It is identified by an orange and red triangular sign mounted on the rear of the vehicle. These signs help motorists recognize the vehicle ahead more quickly. The sooner you can identify a slow-moving vehicle the more time you have to respond by reducing your speed. Slow-moving vehicles may make wide turns at unmarked entrances to the right or left of the roadway. Some farm equipment is wider than the road itself. Some wagons, or equipment, may sway on the roadway and you might not be able to see the driver.
When driving a slow-moving vehicle causes traffic delays, it may pull over to the side of the road, if and when it is possible and safe to do so, in order to let others go by safely. Agricultural vehicle operators have a right to drive their vehicles on the road. Keep a safe following distance behind slow-moving vehicles so the operator can see you, or you can see them, if possible. It may be necessary to allow for more than a four-second following distance. Yield to wide equipment on narrow roads. Pass slow-moving vehicles cautiously, and only if conditions are safe, and there is no oncoming traffic. Be patient and be alert to possible turning vehicles. Share the road safely with large and slow-moving vehicles.
