When escorts are required

Escort requirements key off load width, height, and length — and every state draws the lines differently. As a rule of thumb, loads over 12′ wide need at least one pilot car in most Western states, with a second escort and high pole car coming in as dimensions grow. Your permit states the final word.

California requirements

California spells escort duties out on the permit itself. The basics every escort needs on a CA move:

✓
"OVERSIZE LOAD" signs front and rear, red or orange flags on all corners of the load.
✓
360° amber beacon and two-way radio contact with the truck at all times.
✓
The Caltrans permit lists escort count and position for the exact route — positions can change mid-route.

Certification & equipment

Frequently asked questions

Can I use my own pilot cars?

Yes, if the drivers carry the certification and equipment each state requires. We can also supply certified escorts with your permit.

Do requirements change at night?

Often — some states add an escort or prohibit night moves for wide loads entirely. Check the permit for your travel window.

What does a high pole car actually do?

Runs ahead with a pole set slightly above your load height, calling back wires, signals, and low structures before the load reaches them.
