External Bridge:

Maximum legal weight may be determined by measuring the external/outer (distance from the center first axle to the center of the last axle) and locating that distance in the left-hand column of TABLE 2. Read the weight under the correct column for the number of axles on your vehicle.

Internal Bridge (inner bridge):

  • There are three requirements which cause a vehicle to be subject to internal bridge:
  • Operation on an Interstate highway
  • Vehicle or combination is subject to Table 2 o 4 axles and 47' or more wheel base; or o 5 axles and 41' or more wheel base; or o 6 axles and 33' or more wheel base
  • Vehicle or combination weighs over 73,271 pounds
  • On Interstate highways, your vehicle’s legal weight will also be subject to the internal bridge weight limits found in Table 2 (the distance between the centers of two or more axles, but not the entire external/outer bridge). For example, the internal bridge can be both sets of tandem axles (4-axle bridge) or the axles of the tractor (3-axle bridge).
