Compliance with Implements of Husbandry law kicks in Nov. 1

Compliance with Implements of Husbandry law kicks in Nov. 1
Here's a brief overview of the law

What's so special about Nov. 1? One of the main provisions in the Implements of Husbandry law deals with what are statutorily defined as "wide" IOH.

If not already installed on original equipment, additional lighting and marking features will be required for IOH that exceed 15 feet in width or operate over the centerline of a roadway when traveling. The legislature gave farmers 18 months after Act 377 was signed to come into compliance. That 18-month period ends Nov. 1.

Here is a brief overview of what the additional lighting and marking requirements are:

Compliance with Implements of Husbandry law kicks in Nov. 1

* For self-propelled IOH, including farm tractors, in excess of 12 feet they must be equipped with a 360-degree yellow or amber rotating strobe or beacon mounted at the highest practicable point, or two flashing amber lights visible to the front and rear.

* All "wide" IOH must have: 1) at least two amber flashing lights, visible from both the front and rear, mounted to mark the lateral extremities; 2) red retroreflective material, visible to the rear, placed to mark the lateral extremities; 3) yellow retroreflective material, visible to the front, placed to mark the lateral extremities; 4) at least two red tail lamps mounted to the rear (hardwiring is not required) and; 5) one slow moving vehicle (SMV) sign.  At times other than hours of darkness, a wide IOH may be operated without additional lighting and marking if it has an escort vehicle with hazard lights activated and has two orange or red flags at the rear to mark the lateral extremities.   

* All IOH wider than 22 feet must meet the wide IOH lighting and marking requirements, in addition to having at least one escort vehicle with the hazard lights activated when traveling distances more than a half mile.

* During hours of darkness each vehicle in an agricultural train (three-vehicle IOH combination) must have at least one red or amber light or one red or amber reflector on each side, and the rearmost vehicle should have an SMV sign.

* An IOH of any width can be transported via a trailer or semitrailer during hours other than hours of darkness from farm-to-field, farm-to-farm or field-to-field. During hours of darkness the width is limited to 8.5 feet. An IOH that is being trailered must comply with the same lighting and marking requirements as if it were being operated on the road (excluding headlamps). Self-propelled IOH and farm tractors exceeding 12 feet must also have the beacon/strobe light or the flashing amber warning lights activated.
