A pilot car is required when your load goes over the width, height or length limits set by the state you’re driving through. As a rough guide, most states call for one escort once a load passes about 12 feet wide, 14 feet 6 inches tall, or 90 to 100 feet long. Many states require two escorts (front and rear) once a load passes about 14 feet wide. The exact numbers change at every state line, and your oversize permit always has the final say.
That last part is where most carriers get caught. A load that is legal with one escort in Oklahoma can need two in Kansas and a height pole in Kentucky. Below, we break down the rules state by state so you can plan your escorts before the truck rolls.
Why Escort Rules Differ in Every State
There is no single federal pilot car law. The federal government sets the standard legal width of 8 feet 6 inches on major highways. After that, each state decides:
- When an oversize load needs an escort
- How many escorts it needs, and whether they run in front, behind or both
- When a height pole car is required
- Whether the escort driver must be certified
- What equipment the escort vehicle must carry
Road type matters too. Most states treat a two-lane highway more strictly than a four-lane divided highway or interstate, because oncoming traffic has nowhere to go. That’s why you’ll often see a front escort required on two-lane roads and only a rear escort on the interstate for the same load.
The Three Triggers: Width, Height and Length
Width is the most common reason for an escort. Wide loads cross into oncoming lanes, cover shoulders, and hit mailboxes and signs.
Height usually calls for a high pole (height pole) car in front. The pole is set slightly above the load’s height, so the escort hits a low wire or bridge before your load does.
Length and overhang usually call for a rear (chase) escort, because long loads swing wide on turns and are hard for passing traffic to judge.
If your load goes over limits in two dimensions at once, for example both wide and long, many states require escorts in front and behind.

— | Over 14′ wide (all highways) | Over 16′ | Superloads: front + rear | |
Over 12′ wide (rear, four-lane) | Over 12′ on two-lane; over 14′ on four-lane | Over 14’11” | Over 75′ (two-lane); over 110′ (four-lane) | |
Over 10′ wide (front, two-lane) | 13’6″+ wide | 15’1″+ | 90’1″–120′ (rear); 120’+ (front + rear) | |
Over 12’4″ wide | 14’4″–17′ wide on undivided roads | Over 14’6″ | Over 110′ | |
Over 14’6″ wide | Over limits in two dimensions | Over 14’6″ | Over 110′ | |
Over 14’6″ wide (front, two-lane) | Depends on road and width | Over 14’4″ | Over 120′ (rear) | |
12’–14′ (escort or amber lights) | Over 14′ wide | May be needed over 14’6″ | Over 100′ on interstate | |
12’–14′ (front, non-divided roads) | Over 14′ on non-divided roads | Over 15′ | 100’+ (1 escort); over 115′ (2 on roads under four lanes) |
These are general guidelines from state DOT rules as of 2026. Your permit may add or change requirements, so always follow the permit.
State-by-State Breakdown
Texas
Texas moves more oversize freight than almost any other state. On two-lane highways, a load over 14 feet up to 16 feet wide needs one front escort. Loads over 16 feet need escorts front and rear. Anything over 17 feet tall needs a front escort with a non-conductive height pole. If a load goes over escort limits in two dimensions, such as 16 feet wide and 112 feet long, you need both a front and a rear escort.
Oklahoma
Oklahoma is strict on width. On two-lane roads, loads over 12 feet up to 14 feet need a front escort, and loads over 14 feet need front and rear. On multi-lane highways, loads over 12 feet need a rear escort. Over 16 feet, you need two escorts on every road. Loads 15’9″ or taller need two escorts plus advance contact with utilities and railroads. Oklahoma also requires escort drivers to be certified, and it accepts certifications from a limited list of partner states. Watch for rush-hour curfews on interstates in Oklahoma, Tulsa and Cleveland counties.

Kansas
Kansas keeps it simple: loads over 14 feet wide need one front and one rear escort on all highways. Loads over 16 feet tall need a height pole. Escort drivers working superloads in Kansas must register each year and hold training from an approved certification state.

Kentucky
Kentucky’s rules change sharply by road type. On two-lane roads, anything over 12 feet wide needs a front and rear escort. On four-lane roads, over 12 feet needs a rear escort, over 14 feet needs front and rear, and over 16 feet needs two front and two rear. Loads over 14’11” tall need a height pole, and any rear overhang over 10 feet needs a rear escort.

Tennessee
Tennessee triggers escorts early. Loads over 10 feet wide need a front escort on two-lane routes. Wider loads add a rear escort on interstates and four-lane roads, and city-limit travel restrictions also apply. Loads 15’1″ and taller need a front escort with a height pole. Length triggers start at 90 feet (rear escort), and loads over 120 feet need front and rear.

Indiana
Indiana requires escorts for loads over 12’4″ wide, 110 feet long or 14’6″ tall. One escort runs in front on undivided roads and in the rear on divided highways. Between 14’4″ and 17′ wide, you need a rear escort on divided highways and front and rear everywhere else.

Illinois
Illinois uses a tiered system:
- One escort: over 14’6″ wide, 110′ long, or 14’6″ high
- Two escorts: over limits in two of those dimensions
- Three escorts: over 16′ wide, 145′ long, or 18′ high
- State Police escort: over 18′ wide, 200′ long, or 18′ high
Illinois also requires a separate escort for each load and generally doesn’t allow convoys.

Iowa
Iowa’s width rules depend on lane width and shoulders. On two-lane roads, loads over 14’6″ need a front escort. On four-lane roads, loads over 16’6″ need a rear escort. Loads over 120 feet need a rear escort. Height pole cars are required from 14’4″ up to 20 feet.

Nebraska
In Nebraska, loads over 12 up to 14 feet wide can use either one pilot car or amber warning lights. Loads over 14 feet need two escorts. Tall loads over 14’6″ may need a height pole depending on the route, and loads over 16 feet need a route survey filed in advance. Lincoln and Omaha have weekday rush-hour curfews.

Arkansas
On roads that are not divided four-lane highways, loads over 12 up to 14 feet wide need one front escort, and loads over 14 feet need front and rear. On divided four-lane highways, loads over 14 feet need one rear escort. Loads over 15 feet tall need a front escort with a clearance bar. Over 17 feet, you need sign-off from utility owners along the route.

Real Example: One Load, Three Different Rule Sets
Say you’re moving a 15-foot-wide, 15-foot-tall piece of equipment from Kansas City to Dallas on I-35:
State on Route | What Published Guidelines Require |
Kansas | Front and rear escorts (over 14′ wide) |
Oklahoma | Rear escort on the interstate (over 12′ up to 16′ on multi-lane) |
Texas | Escort coverage based on road type (over 14′ wide); no height pole needed until 17′ |
One load can need three different escort setups in a single trip. Your escort team has to know where the rules change, be certified where certification is required (Oklahoma is on this route), and still be in position when you cross the next state line.
This is the problem 365 Pilots solves: one dispatch call covers the whole route.
Which States Require Certified Pilot Car Drivers?
Some states require escort operators to complete a state-approved course and pass a test. States with certification programs include Arizona, Colorado, Florida, Georgia, Louisiana, Minnesota, Nevada, New Mexico, New York, Oklahoma, Utah, Virginia and Washington, among others. Some states accept each other’s certifications and some don’t. New York, for example, generally requires its own.
If your route crosses a certification state, your escort must hold a valid certification for it. Using an uncertified escort can lead to fines, delays or a load being shut down at the scale house.
What Happens If You Run Without a Required Escort?
- Fines, which can reach thousands of dollars depending on the state
- Out-of-service orders, where your load sits until compliant escorts arrive
- Permit violations that can affect future permits
- Liability exposure if an accident happens without the required escort
A pilot car costs far less than any of these.

How to Plan Escorts for a Multi-State Move
- Get exact dimensions: width, height, length and overhang, all measured with the load secured.
- Pull permits for every state on the route. Each permit lists its escort conditions.
- Map road types. Two-lane sections usually need more escorts than interstates.
- Check certifications for every state that requires them.
- Plan for tall loads. Book a high pole car, or a full route survey for very tall loads.
- Check curfews and holidays. Many states restrict oversize travel at rush hour and on holidays.
- Book one nationwide team instead of handing off between local escorts at every state line.

Frequently Asked Questions
Q. At what width do you need a pilot car?
In most states, one pilot car is required somewhere between 12 and 14 feet wide, and two are required once a load passes about 14 to 16 feet wide. Tennessee starts earlier (over 10 feet on two-lane roads), while Illinois and Iowa start later (over 14’6″).
Q. When is a height pole required?
It depends on the state. Common triggers are 14’4″ (Iowa), 14’6″ (Illinois, Indiana), 14’11” (Kentucky), 15′ (Arkansas), 16′ (Kansas) and 17′ (Texas).
Q. Do I need a pilot car on the interstate?
Often yes, but usually fewer than on two-lane roads. Many states require only a rear escort on interstates for loads that would need a front escort on two-lane highways.
Q. Who decides how many pilot cars I need?
The state permit office. Your oversize permit lists the exact escort requirements for your load and route, and it overrides general guidelines.
Q. Can one pilot car company cover a multi-state trip?
Yes. A nationwide company like 365 Pilots can assign escorts certified for every state on your route, so you don’t need to swap escorts at state lines.
Q. Do pilot car drivers need to be certified?
In many states, yes, and Oklahoma is one of them. Some states accept other states’ certifications. Always confirm your escort is certified for every state on the route.
