Plymouth County, IA – Drivers across northwest Iowa should prepare to share rural roads with more tractors, combines and other slow moving farm equipment as the fall harvest season gets underway.
According to the Plymouth County Sheriff 's Office, motorists should expect an increase in farm equipment traffic and take additional precautions when approaching or attempting to pass machinery.
Deputies recommend reducing speed when coming up behind farm equipment and leaving plenty of following distance. The extra space can help equipment operators see approaching motorists and keep vehicles out of machinery blind spots.
Drivers should also watch closely for turn signals and other communication from operators. Although a farmer may move toward the side of the roadway, motorists should not assume that means it is immediately safe to pass.
The sheriff's office advises passing only when conditions are safe and in a legal passing zone. Motorists should check carefully for oncoming vehicles and other drivers who may already be attempting to pass.
Farm equipment operators are also being urged to check slow moving vehicle signs, lights and turn signals before traveling. Reflectors and reflective marking tape can make large equipment easier to see around dusk and dawn.
When possible, operators are encouraged to avoid busy traffic periods and find a safe location to allow backed up vehicles to pass.
Extra caution is particularly important around turns. Large agricultural equipment may require significantly more room to maneuver than a passenger vehicle, and motorists may not anticipate how wide an operator needs to swing before completing a turn.
With harvest traffic increasing, the sheriff's office is asking both motorists and equipment operators to stay alert and give one another additional room on the road.
