Any front or rear overhang must be flagged or lighted. Up to 10′ overhang may travel at night, but must be lit and flagged.

Note on Overweight Permits in AZ:

Arizona scales expect permit weights to be very close to actual weights and dimensions. You can buy the permit at the scales to avoid problems, or else make sure you are ordering accurate weights!

Permits are not issued for tow-aways without an inspection report on the tow-away unit, or CalTrans permission and inspection appointment. If the tow- away unit is not registered, it also needs a temporary CA registration, which will be ordered when the permit is ordered. Four- axle tractors must have a CA inspection report or permission and inspection appointment. Single axle jeeps and boosters must have a Caltrans inspection before they can be permitted in California.

Trailers exceeding 48 feet in length are not legal in California unless the kingpin to center of rear axle does not exceed 40 feet! Longer trailers can be permitted only when justified by length of the load.

Los Angeles County also requires the amber lights at all protrusions and at 5-foot intervals completely around the load (and red in the rear), not over 5 feet above ground level. When a rear overhang is 4′ or greater, it requires at least two lights or rear light bar at night. Rear light bar not needed on long load in daylight unless turn signals and brake lights are hidden by load.

Red flags must be placed at the extreme rear end of overlength loads or when there is over 4′ rear overhang. No sign or flag requirements are listed for overheight only loads. For overweight-only loads, you still need Oversize Load signs according to a scale officer, but the rules and regulations do not specify this.

When you get the load on, measure it to confirm dimensions.

Make sure your weights are legal, or accurate if overweight.

Some states require a clear load description (“machinery” does not work), load make, model and serial number if applicable.

Always check your permits for accuracy when you receive them.

Trucking permits usually refer to heavy haul trucking and overweight or over dimensional freight. Permits are required by law for any freight that exceeds the weight or dimensions specified on the state’s website. Permits are required for each state that a truck travels through.

Permits can be bought at the appropriate state agency or through a permitting company. The duration of a permit depends on the state and kind of permit, some are temporary and last only a few days, others can be bought that last a year. You can learn more about permits by watching the video below, reading the transcript, or reading the more detailed discussion below the video.

More Information

What are the rules and exact measurements for trucking permits?

Each state has different rules, regulations, and exact measurements for when a permit is required. Weight is usually broken up into gross, steer, single, tandem, and tridem, which each having different exact weights for each state. For trips that span many states, this can get quite complicated and overwhelming for anyone not familiar with permitting. Additionally, if a load is especially large, depending on the state, there are restrictions on the times of day that that size freight can drive on their roads. Some states even restrict especially large freight to certain roads at specific times.

What about pilot cars?

Pilot cars are usually required for extra large freight, however, the exact measurements when pilot cars become necessary depends on the state. Some states also require police escort for especially large or dangerous freight.

What if a truck doesn’t have the proper permits?

If a truck, which is overweight or overdimensional, drives through a state without the proper permits, they will be fined and forced to obtain the proper temporary permits. Usually the truck is stopped until those permits are acquired which can mean long delays, or missed pick ups. This is why it is important to get all the required permits for each trip before actually making the trip.
