Escort Vehicles for Wide Loads

When equipment is too wide or too slow for a typical lane, an escort vehicle can give other drivers extra warning. The rules and best practices depend on where you are driving.

What is an escort vehicle?

An escort, or pilot, vehicle travels with oversize equipment to warn other drivers and help the operator manage traffic. It may travel ahead, behind or both, depending on the situation and local rules.

An escort also helps the equipment operator, who may not see traffic behind or beside a wide machine. A second set of eyes can spot trouble before it reaches you. Some farms hire an experienced local service and others use a trained family member or employee. Either way, the people involved need clear instructions and an understanding of local rules. Ask the official agency what qualifications, if any, they require.

When might I need one?

Whether you need an escort depends on the width, length and height of your load and on state and local rules. Those rules vary a lot, so I am not stating any measurement here.

Check with your state department of transportation, the state highway patrol, your county road office and your extension service before moving wide equipment.

• Width, length and height of the load
• State and county permit rules
• Time of day and traffic conditions

What should the escort vehicle be like?

It should be reliable and well maintained, with working lights and a clear way to communicate with the equipment operator. Some states require specific signs or lights, so confirm the requirements with the official agency.

Do not assume that a farm truck with flashers is enough. Ask the state office what they expect, and follow the manufacturer's guidance for any added lighting.

Treat the escort vehicle as part of the safety system, not a formality. Lights must be tested, tires and brakes checked and the driver fully briefed before the trip begins.

• Working headlights, brake lights and flashers
• Clear communication with the operator
• Required signs or lights as set by the state
• A driver who is rested and focused

How do the driver and escort work together?

Before the trip, agree on the route, the speeds, hand or radio signals and what to do if you must stop. The escort driver should know the plan for bridges, turns and where to pull over.

During the move, keep radio talk short and clear. If anyone is unsure, stop in a safe place and sort it out rather than guessing.

If you cannot reach your escort on the radio, stop in a safe place and sort it out. Never continue a move without communication just to save time.

What route planning helps most?

Look for narrow bridges, tight corners, overhead wires, construction and school or event traffic. Choose times when roads are quieter and the light is good.

Have a backup route, and make sure local authorities or road crews know if the move affects them. Check the weather before you go.

Consider local events, harvest traffic and weather. Fog, rain and low sun can make even a well-marked load hard to see, so build in the option to wait.

• Narrow bridges and tight corners
• Overhead wires and low clearances
• Fog, rain and low sun

What should I do if something goes wrong?

If the equipment breaks down or a crash occurs, get everyone to a safe place away from traffic and call 911 if anyone is hurt or traffic is in danger. Use hazard lights and warning devices as your training describes.

Review your plan with everyone involved, and keep contact numbers for the sheriff, a tow service and your insurance agent on hand.

After the move, talk about what went well and what was difficult. A short review helps you refine the plan for the next trip and lets everyone feel heard.

Who should I ask for help planning?

Start with the agencies that set the rules in your area, such as your state transportation department and the county road office. They can explain permits, route limits and whether a particular movement needs an escort.

Extension educators, your insurance safety adviser and neighboring farmers who move large equipment often are also good sources. Learn from their experience, but always verify any rule with the official agency before you rely on it.
