Note 1: No overall length limitation applies to a semi-trailer unit with a semi-trailer up to 53 feet
in length. For purposes of 700 CMR 7.07(4): Table 8, the combination of a motor vehicle
designed for towing and a vehicle or combination of vehicles being towed because of
disablement or emergency does not constitute a vehicle combination and thus is not subject as
a vehicle combination to the length limitations of 700 CMR 7.07(4)(a)3., but a Massachusetts
State Police officer or an official of the Department designated to make such decisions may
preclude such a towing motor vehicle and towed vehicle or vehicle combination from using a
way for reasons of safety.
Note 2: The vehicle length includes front and rear bumpers, but does not include a load
overhang up to three feet beyond the foremost part of the front transporting vehicle or more than
four feet beyond the rear bed of the rear vehicle.
Note 3: A number of vehicles may be transported in combination by means of saddlemount
combination or fullmount mechanism. Vehicles using these mechanisms must conform to
M.G.L. c. 90, § 19F.
Note 4: Subject to the restrictions that 700 CMR 7.07(4)(e) and 7.08 impose, a tandem unit may
operate on a way without a special permit with respect to its length, provided that:
1. the overall total number of semi-trailers or trailers in the tandem unit is no greater than
two;
2. each semi-trailer or trailer of the tandem unit does not exceed 28 feet in length, without
regard to the overall length of the tandem unit; and
3. a tandem unit with semi-trailers or trailers that do not exceed 28½ feet in length, if such
semi-trailers or trailers were actually and lawfully operating on December 1, 1982, as part
of tandem units within a 65 foot overall length limit in any state, may similarly operate on
a way without a special permit with respect to its length.
(b) Circumstances under Which a Special Permit Is Required. A motor vehicle, vehicle, or
vehicle combination requires a special permit with respect to its size only when compliance
with the maximum size limitations specified in 700 CMR 7.07(4)(a)1., 2., or 3. is impossible
or impractical.
(c) Type of Special Permit Issued (Over-size). The Department issues special permits for
over-size vehicles in accordance with the following provisions:
1. Irreducible Load Permit. A vehicle requires an irreducible load permit if the vehicle
width exceeds the maximum vehicle width permitted under 700 CMR 7.07(4)(a)1.; the
vehicle height exceeds the maximum vehicle height permitted under 700 CMR
7.07(4)(a)2.; or, the vehicle length exceeds the maximum vehicle length allowed for a
vehicle of its type as specified in 700 CMR 7.07(4)(a)3.
The Department does not issue an irreducible load permit if it believes that a load can
be divided or arranged so as to conform with the limitations on its width, height, or
length. The Department may prohibit an over-size vehicle from using a way if, in the
opinion of the Chief Engineer, safety or the public convenience warrants the prohibition.
The Department may issue, upon the approval of the Chief Engineer, an irreducible
load permit in accordance with the procedures and subject to the terms of 700 CMR
7.07(2) and (4)(f).
The applicant must pay the fee that is specified on the permit application and in
700 CMR 7.07(3): Table 5. This fee is in addition to the regular toll charge based on the
classification of the vehicle under 700 CMR 7.03(1). In the case of multiple trips of a
single vehicle or a convoy of vehicles, the fee represents the total fee due up to a
maximum number of trips of two or more as determined by the Chief Engineer, provided
that the applicant specifies on the application referred to in 700 CMR 7.07(2)(a) the
number of anticipated multiple trips, the time period in which they will be completed,
and any other information that the application or the Chief Engineer requires.
2. Use of the Ted Williams Tunnel, Including the South Boston Bypass Road. A
vehicle that exceeds any of the applicable maximum dimensions specified in 700 CMR
7.07(4)(a)1., 2., or 3. requires an irreducible load permit for use of the Ted Williams
Tunnel, including the South Boston Bypass Road for construction equipment. An
original annual permit for construction equipment issued by the Department must be kept
in an accessible place in the vehicle for which it was issued and must be presented to an
official or employee of the Department, or Massachusetts State Police officer on demand.
The operator of the vehicle is responsible for the regular toll charge based on the
classification of the vehicle under 700 CMR 7.03(1).
(d) Pilot Car.
1. When Required. A pilot car must follow an over-size vehicle if: the overhang is four
or more feet and the load consists of poles, masts, booms, or similar shapes or if the
overhang is ten feet or more; the over-size vehicle is a drill rig with boom, a shovel, or
a crane; the over-size vehicle is odd-shaped or has an odd-shaped load; or the over-size
vehicle is not a tandem unit or a semi-trailer unit with a semi-trailer of not more than 53
feet and has a length of more than 90 feet up to and including 100 feet or a width of more
than 12 feet up to and including 13'6".
2. When Required – Vehicles Traveling on the MHS. A pilot car must follow an
over-size vehicle traveling on the MHS if: the overhang is four or more feet and the load
consists of poles, masts, booms, or similar shapes or if the overhang is ten feet or more;
the over-size vehicle is a drill rig with boom, a shovel, or a crane; the over-size vehicle
is odd shaped or has an odd shaped load; or the over-size vehicle is not a tandem unit or
a semi-trailer unit with a semi-trailer of not more than 53 feet and has a length of more
than 80 feet and up to and including 95 feet, or a width of more than 12 feet.
3. Convoy Pilot Car. If two or more over-size vehicles are in convoy, one may be pilot
for the other, but a separate pilot car must follow the last over-size vehicle. MassDOT,
in its sole discretion, may allow for convoys. MassDOT may place any restrictions in the
permit it deems necessary for the safe travel of such vehicles including, but not limited
to, time of travel, dimensional restrictions, and/or escort requirements.
4. Preceding and Following Pilot Cars. If an over-size vehicle is not a tandem unit or
a semi-trailer unit with a semi-trailer of not more than 53 feet and has a length of more
than 100 feet up to and including 135 feet, or width of more than 13'6" up to and
including 16 feet, it must have pilot cars preceding and following it.
5. Preceding and Following Pilot Cars - Vehicles Traveling on the MHS. If an over-size
vehicle traveling on the MHS is not a tandem unit or a semi-trailer unit with semi-trailer
of not more than 53 feet and has a length of more than 95 feet, or width of more than
13'6" up to and including 16 feet, it must have pilot cars preceding and following it.
6. Requirements for a Pilot Car. A pilot car must be a truck with two axles and four
wheels or a private passenger motor vehicle and must have two flashing amber lights
visible from front and rear; 24 inch by 24 inch red flags on the right and left rear of the
pilot car; and a sign reading: "Oversize Load".
7. State Police Escort. In addition to the requirements with respect to a pilot car as
specified in 700 CMR 7.07(4)(d), an over-size vehicle, with its load, that is wider than
16 feet or longer than 135 feet must be escorted by two motor vehicles of the
Massachusetts State Police. Any vehicle that, in the opinion of t he Chief Engineer, may
be incapable of operating at a minimum speed such that it may pose a danger to
individuals, property, or the safe operation of a way, may be required to be accompanied
by motor vehicles of the Massachusetts State Police.
8. Oversize Load Sign. An oversize vehicle that is not required to be accompanied by
a pilot car must have a sign on the rear reading: "Oversize Load".
(e) Tandem Units and Certain Saddlemount Combinations Not Permitted in the Tunnels.
Subject to 700 CMR 7.07(3)(c)4., and notwithstanding any other provision of 700 CMR 7.07
to the contrary, and irrespective of their length, tandem units, double saddlemount
combinations, and triple saddlemount combinations are not permitted in the Tunnels.
(f) Height Indication. No vehicle that has a total height exceeding ten feet, excluding the
height of its load, may be operated on a way unless the measurement of the total height is
painted or printed in letters and numerals at least four inches high in a conspicuous place
upon the side or front of the vehicle.
(g) Responsibility of Operator. The operator of an over-size vehicle is responsible for
checking the clearance of the vehicle and its load through any toll lane or canopy and for
checking structures on a way for available clearance with respect to movements by the
oversize vehicle or by load movements. The operator is subject to the penalty provided in
700 CMR 7.13(3)(a) for failure to exercise this care. The Department imposes this penalty
in addition to holding the operator liable for the damage resulting from failure to exercise this
care.
