For this reason, the third week of September is recognized as National Farm Safety and Health Week. PassingIt is typically illegal to pass farm equipment in a no-passing zone, regardless of speed. Farm equipment often has two flashing amber or yellow lights on the cab or fenders. Equip all equipment operators with road safety training, plan routes to avoid high-risk areas and review local permit requirements before operating. Attentiveness is a constant requirement on the road but being prepared and exercising caution during peak times are vital to a successful harvest.
