Road Safety Need Is Heightened At Harvest

Road Safety Need Is Heightened At Harvest

As harvest gets underway, motorists will be encountering slow-moving agricultural equipment on Iowa roadways. All drivers need to keep in mind road safety is a shared responsibility.

Getting the harvest moved from the field to your grain bins or to the elevator in town can be dangerous work, but doing it in traffic on Iowa's highways and county roads extends the hazards to other drivers and their passengers.

Various conditions can create additional risks on Iowa roadways during harvest.

Those conditions include drivers who don't understand how to avoid collisions with ag equipment, and motorists who are driving distracted and also the heavier than normal traffic on rural highways due to flooding and construction detours.

Charles Schwab, an Iowa State University Extension farm safety specialist, says highway safety is a shared responsibility for both the motor vehicle operators and ag equipment operators. Both have reasons and rights to be on those roads.

Farm equipment operators need to watch out for motorists on roadways

Agricultural equipment operators need to remember that vehicle drivers, especially those rerouted to rural highways, may not have the necessary understanding to avoid collision with agricultural equipment: how to approach a slow moving vehicle (SMV), left turns of equipment and how to pass oversized equipment and unique shapes of combines. Schwab reminds operators of agricultural equipment to make sure all SMV emblems are properly mounted, not faded, and to always signal before making turns.

"Motorists may be unfamiliar with the outlines of farm equipment, especially at dusk when operators are returning from fields or moving between fields," he says. "Unfamiliarity can cause a split-second delay in reaction that, in many cases, can lead to a collision."

Schwab says proper lighting and marking for farm vehicles is only half of the solution. Motor vehicle drivers also must be attentive, watch for farm traffic and heed the signs especially in the weeks ahead.

"Motor vehicle operators need to be patient, show understanding and not drive distracted – rushing and not paying attention to the road causes opportunities for collisions," he warns. "It is important to understand the issue about coming upon a SMV when traveling at a high rate of speed."

Follow these defensive driving tips for use on rural roads

Schwab offers the following defensive-driving tips for rural roads this fall:

As soon as you see a slow-moving vehicle (SMV) emblem, brake as if you were approaching a stop sign.

Look for hand or turn signals from the farm vehicle operator, indicating a left turn.

When passing, make sure you can see the farm vehicle in your rearview mirror before you get back in your lane.

While farm tractors and other farm equipment comprise a small percent of total motor vehicles nationally, the percentage of fatal motor vehicle collisions involving farm equipment is almost five times higher than other vehicle collisions. In crashes involving farm vehicles, the farm vehicle operator was killed nearly twice as often as an occupant of the other motor vehicle.

Most likely types of collisions are left-turn and rear-end collisions

The most likely types of collisions are left-turn and rear-end collisions. The left-turn collision happens when the farm vehicle is about to make a wide left turn and the vehicle behind begins to pass. The second most common incident is the rear-end collision, where another vehicle approaches farm equipment and is unable to slow down to avoid a collision. This happens because of large difference in travel speeds of these two types of vehicles.

"Vehicle drivers must stay alert, especially in areas where rural roadways are experiencing heavier than normal traffic due to flooding and construction detours," Schwab cautions. "Higher speeds used on rural roads, changeable conditions and a variety of traffic all contribute to injuries. Motorists must stay attentive and watch for farm traffic, which can be difficult to spot, recognizing it travels at much slower speeds than normal traffic."

Schwab also reminds vehicle drivers that agricultural equipment operators in these areas will be limited in their ability to use the shoulder as they move down the road, since shoulder conditions could have changed considerably this summer because of flooding (washed away, weak or steeper than before).
