Most states require one pilot car over 12 feet wide. Of the 36 states that set a two-escort width, 24 require two, front and rear, from 14 to 16 feet. In 21 of the 42 states that set a height, a front height pole car starts between 14 feet 5 inches and 15 feet 6 inches. Length escorts start near 90 to 110 feet, and police escorts near 16 feet wide. Each state differs; the table below has all 50.

This page covers when a load needs a pilot car. To get certified as an escort driver, see Pilot Car Certification by State.

Pilot car requirements in all 50 states

Each row comes from the state’s own rule, manual or DOT page, linked in the Sources column. “1” means one escort and “2” means front and rear. “See permit” means the state’s published rule gave no clear number, so the issued permit and the permit office decide.

When do you need a pilot car?

You need a pilot car when any dimension passes your state’s trigger or the permit names one. Common triggers are over 12 feet wide, over 90 to 110 feet long, or over about 14 feet 6 inches high. Road type changes the count: two-lane roads usually need a front escort, divided highways a rear one.

• Width, height and length are separate triggers. The most demanding one sets the crew.
• Road type changes the position. Utah, for example, starts at 12 feet on secondary roads and 14 feet on freeways in daylight.
• Route maps decide in some states. Arizona, California, Idaho and Oregon set escorts by route, so read the permit.

Start with the four numbers that decide whether you need a permit, then compare the load with your state’s row above.

When do you need two pilot cars?

Of the 36 states that set a two-escort width, 24 add the second escort, front and rear, between 14 and 16 feet wide. Some require two far sooner on two-lane roads: Washington over 11 feet, and Kentucky and Virginia over 12 feet. Illinois skips straight from one escort over 14 feet 6 inches to three over 16 feet.

Two escorts also come from length. Alabama, New Jersey, Rhode Island and Tennessee each have a length where one escort becomes two.

When do you need a height pole car?

In 21 of the 42 states that set a height, a front escort with a height pole or measuring device starts between 14 feet 5 inches and 15 feet 6 inches. Texas, Montana, Wyoming and Alaska start at 17 feet. The pole is set slightly above the load, so a strike warns the truck before the load reaches the wire or bridge.

The pole car drives far enough ahead for the truck to stop. Pennsylvania sets that at 1,000 to 3,000 feet. Florida and Utah require a non-conductive pole.

“Communication over the CB is crucial to our role.”

When is a police escort required?

Police escorts usually start at 16 to 18 feet wide. Maryland, Maine, Louisiana, New York and South Carolina start at 16 feet; Illinois and Tennessee at 18 feet. Many states set no size and require police only when the permit office says so, as in Texas, Ohio and Connecticut.

Some triggers are length, not width: Florida over 250 feet and Alabama over 150 feet. Book police early; they work to their own schedule.

Do pilot car drivers need a certification?

In at least 15 states, every escort driver needs state-approved training or certification. They include Colorado, Florida, Georgia, Minnesota, New York, North Carolina, Oklahoma, Utah, Virginia and Washington. Texas, Missouri and Oregon require training for escorts who flag traffic. New Jersey’s permit guide says it has no certification.

“See permit” in the certification column means we did not find a certification rule in the state’s published sources. It does not mean none applies. The pilot car certification guide covers courses and reciprocity.

How do you check one load?

Measure the loaded width, height and length, then read each state’s row for the route. Count escorts per state, because the number changes at every state line and often when you leave the Interstate. Finally, compare that count with the permit, which wins.

1. Measure the load as it will travel, including overhang.
2. List every state and road type on the route.
3. Read each state’s row above and its linked rule.
4. Match the crew to the issued permit before you book.

How does the pilot car get the route?

The escort needs the road-by-road route, the dimensions and the curfews before the first mile. Whitney’s own ask to a driver is one sentence.

"Send me the permit so I can look over the route."

A shared RouteAll route opens for the escort with no account and no charge. Check the route against the issued permit before sharing it. Your escort driver should not need a subscription explains why.

Before you roll

The escort count changes at every state line and often when you leave the Interstate. Read the permit for each state, agree the radio channel with the pilot car, and confirm who runs the pole. If the permit and this table disagree, the permit wins.
