Sharing the Road with Farm Equipment in Illinois
Every fall, tractors, combines and farm trucks move between fields on the same roads Central Illinois drivers use every day. Here is what the Illinois State Police (ISP) and University of Illinois Extension say drivers should do when they come up behind farm equipment, from the orange slow-moving vehicle sign to when you can legally pass.
The short answer
Slow down as soon as you see farm equipment or the orange slow-moving vehicle triangle, leave extra following distance and be patient. Pass only where it is safe and legal, never in a no-passing zone or within 100 feet of an intersection, railroad crossing or bridge, and watch for the farmer's turn signal or hand signal before you go.
Watch for the orange triangle
Illinois Extension says to watch for the Slow-Moving Vehicle (SMV) sign, a bright orange triangle trimmed with red reflective tape. The emblem warns drivers that the vehicle they are approaching is only capable of moving up to 25 mph and poses a hazard. It is required by law on all "implements of husbandry," including tractors, combines and other farm equipment, and flashing lights or rotating beacons do not take its place.
The ISP adds that flashing amber lights mean caution, and orange and red reflective triangles warn motorists that farm equipment travels at slower speeds. A fully loaded tractor, combine or truck moves much slower than the average car or truck, Illinois Extension says: a car going 55 mph takes 5 seconds to brake 300 feet, the length of a football field, to avoid rear-ending farm equipment traveling 15 mph.
From University of Illinois Extension, "Stay aware, safely share rural roads during fall harvest" (October 15, 2019), and ISP harvest safety releases (September 2023 and September 2025), read October 29, 2026.
Driving tips for harvest season
The ISP encourages motorists to follow these tips:
Be patient
Share the road and be patient. Allow extra travel time.
Back off
Increase your following distance to improve sight lines when you drive behind wide, slow-moving vehicles.
Slow down
Reduce speed when you encounter farm equipment on public roads.
Read the warnings
Flashing amber lights mean caution, and orange and red reflective triangles warn that farm equipment travels at slower speeds.
Watch for turns
Newer equipment may have turn signals, but older equipment may not, so watch for the farmer's hand signals.
Make room
Be prepared to yield to wide equipment.

Passing farm equipment safely
The ISP says it is illegal to pass in a no-passing lane or within 100 feet of an intersection, railroad crossing or bridge. Improper passing, including around farm equipment, can be deadly, so be cautious when you pull back into your lane.
Before you try to pass, Illinois Extension says to make sure the farmer is not preparing to turn, and to assume the driver of the farm equipment may not see you. Operators cannot see drivers who follow closely or travel close to the side of the equipment. Modern farm equipment is often wider than a traffic lane, particularly on bridges and raised roadways, so oncoming traffic should be prepared to let wide equipment pass.

What farmers are asked to do
Sharing the road goes both ways. The ISP and Illinois Extension ask farm equipment operators to:
| Tip | Source |
|---|---|
| Avoid rush hours and busier roadways when possible. | ISP |
| Avoid driving tractors on roadways in bad weather, in low visibility and after dark. | ISP |
| Wipe dust, mud and debris off reflectors, flashing lights and other warning devices before entering the roadway. | ISP |
| Watch for traffic backing up and, when road and shoulder conditions are safe, pull over to the right to let it pass. | ISP |
| Reduce the width of combines by removing the harvesting heads when possible. | ISP (2023) |
| Use hazards and turn signals diligently, and replace faded SMV emblems and reflective material. | Illinois Extension |
The ISP 2023 release also notes that farm machinery cannot be driven or towed on controlled access highways.

Farm equipment on the road FAQ
What does the orange triangle on a tractor mean?
It is the Slow-Moving Vehicle (SMV) emblem, a bright orange triangle trimmed with red reflective tape. University of Illinois Extension says it warns drivers that the vehicle ahead can only move up to 25 mph, and that the emblem is required by law on all farm equipment, including tractors and combines.
When is harvest season in Illinois?
The Illinois State Police (ISP) says the fall harvest season typically begins in early September and can last into November, and farmers move equipment along roadways throughout those months.
Can I pass a tractor on a two-lane road?
Only when it is safe and legal. The ISP says it is illegal to pass in a no-passing zone or within 100 feet of an intersection, railroad crossing or bridge, and that improper passing, including around farm equipment, can be deadly. Illinois Extension adds: before you pass, make sure the farmer is not preparing to turn.
How fast does a car close in on farm equipment?
Quickly. Illinois Extension says a car going 55 mph takes 5 seconds to brake 300 feet, the length of a football field, to avoid rear-ending farm equipment traveling 15 mph.
Why does the farmer not pull over right away?
Illinois Extension says farmers will pull off the road to let drivers pass when it is safe, but they cannot move aside immediately, because soft, wet, rutted or steep shoulders can cause farm vehicles to tip over.
What do flashing amber lights on farm equipment mean?
The ISP says flashing amber lights mean caution, and orange and red reflective triangles warn drivers that farm equipment travels at slower speeds.
