*(Tandem and Tridem weights may vary depending on axle spacings, and axle width. For example, a tridem with 9′ of axle spacing (4’6 + 4’6) and 8’0 axle width gets 51,450).
Note: A “Class C Tridem Permit” can now be obtained to allow 59,168 pounds at 9′ of Tridem axle spacing (57,960 at 8′, 60,000 at 10′). However, this is only for travel on Interstates 10, 19 and 40, and for the portions of SR68 and US93 connecting I-40 and the Nevada line.  Any other (including detour) routes will disqualify you.

Dozer blades shorter than 14′ wide may be hauled without being detached provided the dozer is firmly supported. If buckets, blades, counterweights, etc., are easy to remove, they must be removed, but can be hauled with the load. Blade can be detached and hauled with the dozer on same trailer if the load would be overweight with or without the blade, but it must be stated on the permit. On wide loads, side mirrors must extend far enough to avoid view being blocked by the load.
SIGNS, FLAGS & LIGHTS: All overwidth vehicles or loads exceeding 9′ in width shall display “Oversize Load” signs. All overwidth loads and vehicles must be flagged with red flags 12″ square or larger on extremities. Any front or rear overhang must be flagged or lighted. Up to 10′ overhang may travel at night, but must be lit and flagged. There are no sign or flag requirements for overheight only or overweight only loads.
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!

Buckets, blades, counterweights do not need to be removed. Blade can be detached and hauled on same trailer with an overweight dozer, but permit must state it (“blade detached and reloaded”). 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.
SIGNS, FLAGS & LIGHTS: Signs and flags are required on vehicles over 8’6″ wide, over 80′ long, or with over 10′ overhang. Signs are also required when overweight only. For night running, amber marker lights are required at front corners of load and one on left outside extreme edge, visible from front and sides, and red at rear corners visible from rear and sides. 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.
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.

Beams, poles, pipes, structural material don’t need permit up to 85 feet long, daylight only, on Interstates and designated roads.
Multiple pieces rule: NC does not allow or permit for multiple pieces on an overlength vehicle/load (over 60’ overall length) on “non-designated” highways. If you are hauling two farm tractors end-to-end and your overall length is 70 feet, we cannot get a NC permit except for Interstate and “designated” US routes (mainly 4-lane US highways). If your route is on other highways (including most US Highways), NC will not give us a permit unless we claim that it is for a single piece.
SIGNS, FLAGS & LIGHTS: “Oversize Load” signs are required at front and rear for all loads exceeding 10 feet wide. Flags are required on each corner and at the widest point of the load for all loads over 8’6″ wide, but the flags “…shall be so mounted as to not increase the overall width of the load.” Rear overhang in excess of 4 feet requires a flag, or at night a red or amber light visible for at least 200 feet.

Permit Ordering Tips:
If you have a computer, temporary restrictions for many states can be accessed via the Safe Travel USA website (www.safetravelusa.com)
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.
