Tractor Operation & SafetyDriving a Tractor on Public Roads
A tractor on a public road is slow, wide and hard to see. Preparation and patience make the trip safer for you and for the drivers behind you.
Key points
- Check lights, brakes, SMV emblem and hitches before leaving the yard.
- Look up your state's rules for farm equipment on roads.
- Drive defensively, pull over to let traffic pass and avoid low-light hours.
- Consider trailering for long or busy routes.
What should you check before taking a tractor on the road?
Do a quick walk-around. Check that tires are in good shape, brake pedals are latched together, steering is tight and every light works. Confirm the slow-moving vehicle emblem is clean, visible and mounted as the manufacturer and your state require.
Remove or raise anything that extends beyond the machine: loader buckets, forks, sprayers or mower decks. A loader bucket should be lowered only as far as is safe and secured as the manual describes. Check the hitch and safety chain on anything you tow.
- Latch brake pedals together for road travel
- Clean the SMV emblem, mirrors and lights
- Secure or remove loaders and wide attachments
- Fill the fuel tank before leaving
Which laws apply to tractors on public roads?
Rules differ by state and sometimes by county. Topics include lighting, SMV emblems, maximum width and length, speed limits for farm equipment, licensing and towing limits. Do not rely on a neighbor's memory or old advice.
Check with your state department of transportation, the department of motor vehicles, the state highway patrol or the state agriculture department. Your extension office can often point you to a plain-language guide for farm equipment on roads.
If you are not sure what applies, a call to a state agency before the first trip is quicker than explaining yourself roadside afterward.
How do you make a tractor easier for drivers to see?
Drivers approach quickly and often misjudge the speed of a slow vehicle. Use the lights the manufacturer and your state require. Keep reflectors clean and consider daytime lighting, such as flashing amber lights, if your tractor offers them and your state allows them.
Avoid roads at dawn, dusk and in fog where you can. Pick routes with straight stretches and good sight lines, and avoid blind hills and curves when there is a choice.
How should you drive on the road?
Stay as far to the right as is safe. Signal early with your lights or hand signals if you have no turn signals. Watch mirrors and look behind before turning, because traffic may be trying to pass. Do not pass other vehicles on a tractor unless the law and conditions plainly allow it.
Slow down for bridges, narrow shoulders and railroad crossings. Pull over at a safe spot when a line of traffic builds up, and let drivers by. A courteous pull-off is better than driving with impatient cars on your tail.
- Do not carry passengers
- Keep speed within what the machine, load and brakes can handle
- Never coast out of gear
- Look for overhead lines before raising any implement
What about towing implements and wide loads?
Towed equipment adds length, width and braking demands. Use the proper hitch, pins and safety chains. Check that the implement is raised, locked and carrying no loose material. A 30-acre hay operation moving a baler or a wagon between fields should plan a route with room to pass.
If an implement is wider than the lane, state rules may require escort vehicles, flags or permits. Check before you go, not after.
Keep your insurance agent informed if you use farm tractors on roads regularly, since coverage questions after a collision are much easier to settle beforehand.
When is it better to trailer than drive?
For long distances, busy highways or older tractors with limited brakes and lighting, loading the tractor on a properly rated trailer may be safer. Use a tow vehicle and trailer rated for the weight, with working brakes and lights.
If you are unsure about the legal and mechanical side, ask your state DOT or a qualified equipment hauler.
Plan the return trip too. Loads, light and traffic change over a day, and a route that was easy at midmorning can be hard at dusk. Leave time to get home before dark.
What should you know about railroad crossings, bridges and hills?
Cross railroad tracks at a right angle and only when you are sure you will not stall on them. Do not shift gears on the tracks. If you do stall, get away from the tractor and follow the posted emergency contact instructions on the crossing sign.
On bridges, watch for posted weight limits and narrow lanes. Downhill, use a low gear and let the engine help with braking rather than relying on brakes alone, and keep both brake pedals latched. Tractors with a loaded wagon behind need extra stopping distance.
