Current through August 31, 2023
Annual Disabled Vehicle permits will be issued to heavy duty
				wrecker trucks or other vehicles used for the removal and secondary movement of
				disabled trucks and/or trailers or combinations and their unladen return,
				subject to the following rules: (3-31-22)
01.
Permitted Vehicle
. The
			 permitted vehicle involved in the removal of disabled vehicles shall be the
			 proper class of vehicle and shall have adequate gross vehicle weight and
			 traction to control the combination of wrecker and attached vehicles, and shall
			 provide brakes to the trailer axles and stop signal and clearance lights to
			 such towed disabled vehicle or vehicle combinations. (3-31-22)
02.
Loaded Weight
. Loaded weight
			 of the permitted vehicle's drive axle(s) will be permitted up to the basic
			 allowable unit weight as shown on the current Idaho Transportation Department
			 Route Capacity Map for the corresponding colored route, unless the highway
			 route is posted with a weight restriction. The current Route Capacity Map is
			 maintained by the Special Permit Office and is available to the public from the
			 Special Permit Office at the address listed in rule
			 39.03.03, and Idaho Ports of
			 Entry or on line at itd.idaho.gov. Length of the combination will be limited to
			 the legal or permitted length of the disabled combination plus forty-five (45')
			 feet. Width will be limited to ten (10 ') feet or to the permitted width of the
			 permitted disabled over-width vehicle/load. All VLS axles must be fully
			 deployed when exceeding legal axle weights. (3-31-22)
a. Disabled Vehicle and Snowplow permits
			 involving overweight loadings will be available at the following levels:
			 (3-31-22)
i. Red Routes - The red routes
			 contain posted bridges and require approval or analysis from the Department. A
			 vehicle configuration may be issued an annual Disabled Vehicle and Snowplow
			 permit for travel on red routes, upon completion of an analysis verifying the
			 requested weights are acceptable. The annual permit will be issued for a
			 specific vehicle configuration, operating on a specific route, at specific
			 weights. All information will be listed on the annual permit and will be
			 subject to revocation at such time the vehicle configuration changes (such as
			 axle spacings), the approved weights change, or a bridge rating changes.
			 (3-31-22)
ii. Yellow Routes - The
			 yellow overweight level is based on a single axle loading of twenty-two
			 thousand five hundred (22,500) pounds, a tandem axle loading of thirty-eight
			 thousand (38,000) pounds, and a tridem axle loading of forty-eight thousand
			 (48,000) pounds or the equivalent loading as determined by spacings and number
			 of axles and computed by applying the formula W = 560 ((LN/N-1) + 12N + 36).
			 (3-31-22)
iii. Orange Routes - The
			 orange overweight level is based on a single axle loading of twenty-four
			 thousand (24,000) pounds, a tandem axle loading of forty-one thousand (41,000)
			 pounds, and a tridem axle loading of fifty-one thousand five hundred (51,500)
			 pounds or the equivalent loading as determined by spacings and number of axles
			 and computed by applying the formula W = 600 ((LN/N-1) + 12N + 36).
			 (3-31-22)
iv. Green Routes - The
			 green overweight level is based on a single axle loading of twenty-five
			 thousand five hundred (25,500) pounds, a tandem axle loading of forty-three
			 thousand five hundred (43,500) pounds and a tridem axle loading of fifty-four
			 thousand five hundred (54,500) pounds or the equivalent loading as determined
			 by spacings and number of axles and computed by applying the formula W = 640
			 ((LN/N-1) + 12N +36). (3-31-22)
v.
			 Blue Routes - The blue overweight level is based on a single axle loading of
			 twenty-seven thousand (27,000) pounds, a tandem axle loading of forty-six
			 thousand (46,000) pounds, and a tridem axle loading of fifty-seven thousand
			 five hundred (57,500) pounds or the equivalent loading as determined by
			 spacings and number of axles and computed by applying the formula W = 675
			 ((LN/N-1) + 12N + 36). (3-31-22)
vi. Purple Routes - The purple overweight
			 level is based on a single axle loading of thirty thousand (30,000) pounds, a
			 tandem axle loading of fifty-one thousand five hundred (51,500) pounds, and a
			 tridem axle loading of sixty-four thousand five hundred (64,500) pounds or the
			 equivalent loading as determined by spacings and number of axles and computed
			 by applying the formula W = 755 ((LN/N-1) + 12N + 36). (3-31-22)
vii. Black Routes - The black overweight
			 level is based on a single axle loading of thirty-three thousand (33,000)
			 pounds, a tandem axle loading of fifty-six thousand (56,000) pounds, and a
			 tridem axle loading of seventy thousand five hundred (70,500) pounds or the
			 equivalent loading as determined by spacings and number of axles and computed
			 by applying the formula W = 825 ((LN/N-1) + 12N + 36). (3-31-22)
viii. Vehicles or loads exceeding the axle
			 weights, groups of axle weights, or total gross weights allowed on any of the
			 overweight levels must operate by single trip permit only. (3-31-22)
ix. Weight Formula. "W" is the maximum weight
			 in pounds (to the nearest five hundred (500) pounds) carried on any group of
			 two (2) or more consecutive axles. "L" is the distance in feet between the
			 extremes of any group of two (2) or more consecutive axles, "N" is the number
			 of axles under consideration and "F" is the load factor most appropriate based
			 on the most critical bridge on the highway route. (3-31-22)
