Overhead Clearance

When height of load exceeds legal limit (14 ft.) it becomes the responsibility of the permittee to check all underpasses, bridges, overhead wires or other structures for impaired vertical clearance and to bypass or arrange clearance at such locations.

Reducible Loads

This permit is issued for the movement of an “extralegal load” as defined in CVC 320.5 when loaded at its least dimensions. This permit may be hauled provided they do not exceed the dimensions of the vehicle or permitted item and the loaded vehicle is of legal axle and gross weights. Overweight permits shall not be issued for items transported on a conventional flat deck trailer unless the deck is needed to support a long fragile load or a long load that would cause unbalanced axle group weights.

Tire Capacity

Permitted axle or axle group weights shall not exceed the rated capacity of vehicle tires except as allowed by Title 13, Article 14, Section 1085 of the California Administrative Code. After January 1, 1988, said weight shall not exceed the rated capacity of vehicle tires.

Booster Type Axles

A booster type axle is an axle, generally, having an air hydraulic cylinder suspension system that can be actuated independent to assume a portion of the weight that would otherwise be carried by adjacent axles. Booster axles and add-on or “Joe Dog” axles shall not be used in the movement or overweight loads.

Travel Way

Where practical, the vehicle shall be kept in the far right lane of the highway and shall not encroach on highway shoulders except where necessary to allow trailing traffic to pass.

Movement during Darkness

“Darkness” is defined in Section 280 of the CVC as being “…any time from one-half hour after sunset to one-half hour before sunrise…”

Holiday Movement

Unless authorized on the face of this permit, movement is prohibited on the following holidays:

  • New Year’s Day
  • Washington’s Birthday (3rd Monday in February)
  • Memorial Day (Last Monday in May)
  • Independence Day
  • Labor Day
  • Veteran’s Day
  • Thanksgiving Day
  • Christmas Day

Moving in Inclement Weather

Movement shall not occur in snow, fog, rain or wind when visibility is restricted to less than 1,000 feet. Movement is prohibited when road surfaces are hazardous to rain, ice, snow or frost, or when use of tire chains is mandatory. No moving shall be done when the velocity  of the wind is such that it causes the vehicle being towed to whip or swerve from side-to-side or fail to flow substantially in the path of the towing vehicle. Any accident caused by excessive wind or weather conditions shall be considered a prima facie violation of this condition.

Pilot Car and Equipment

It shall be the responsibility of the permittee to ensure that pilot car vehicles and operators are equipped and briefed as to their duties prior to movement. Pilot cars shall be single vehicles with a minimum of 60 inches in width, and may operate with a nondestructive vertical clearance measuring device with height in excess of 14 feet. Pilot cars shall be equipped with:

  • One each stop/slow sign paddle;
  • One each orange vest, shirt or jacket;
  • One each red hand flag (18 in. x 18 in. minimum);
  • Two-way radio communication between the pilot car(s) and the transporting vehicle;
  • Top-mounted flashing amber warning light(s). The light(s) shall be visible to the front when leading and to the rear when following, and shall be operated at all times when escorting a permit load. Lights shall be removed or covered with opaque material when not escorting a permit load. Lights shall be removed or covered with opaque material when not escorting movement described on Permit (CVC 25270).
  • Neat, clean and legible sign(s) visible from straight ahead or behind and to 45 degrees either side thereof. The bottom of the sign(s) shall be a minimum of 48 inches above the ground. The sign shall read “OVERSIZE” when viewed from the front or rear. The more definitive signs reading “OVERSIZE LOAD”, “WIDE LOAD”, or “LONG LOAD” may  be substituted for the “OVERSIZE” sign when appropriate. The sign shall be a bright yellow background with black lettering and have a minimum projected area of 440 square inches. The lettering shall have a one-inch minimum brush stroke with a 6′ minimum projected letter height.

Pilot Car Location and Responsibility

A pilot car shall:

  • Precede the load on two or three-lane conventional roads and follow on four or more lane conventional highways and divided highways.
  • Remain right of the centerline of the roadway at all times except when prevented by the physical limitations of the highway. When it becomes necessary because of the physical limitations of the highway. When it becomes necessary because of the physical limitations of the highway to use a portion of the opposing traffic lane, the permit move shall not occupy that lane until it has been advised by the pilot car that the lane is clear of all oncoming traffic. Opposing traffic is not to be stopped, except in extreme emergencies. It shall be the responsibility of the permit move to stop safely and wait until the opposing lane is free of traffic before processing;
  • Maintain proper interval between load and the pilot car to allow passing by other traffic;
  • Accompany the permitted load over all operational California Highway Patrol/Orange Police Department facilities.

A pilot car shall not:

  • Pre-empt opposing traffic;
  • Tow another vehicle while being used as a pilot car;
  • Display the stop/slow sign paddle out of the window of a moving vehicle;
  • Stop opposing traffic except on extreme emergencies;
  • Convoy more than one load at the same time.

When necessary to post a flagman in order to warn and direct traffic, the flagging shall be done in accordance with Title 8, Sections 1598 and 1599 of the California Division of Occupational Safety and Health Construction Safety Orders and Caltrans “Manual of Traffic Controls”. Flagman shall not be younger than 18 years of age.

Axle weights for “Manufactured Housing” (CVC 387) shall not exceed 6,000 pounds per axle.

Tractor units towing manufactured housing as defined in CVC 387 that exceed legal width and up to 12 ft. in width shall be equipped with dual rear wheels and shall have an unladen weight as defined in CVC 660 of not less than 6,500 pounds. Tractor units towing manufacturing housing exceeding 12 ft. in width shall be equipped as required above with an unladen weight as defined in CVC 660 of less than 9,500 pounds.

Open Side Covering

Open sided units shall be covered by plywood, hard board or other rigid material. In lieu of rigid material, suitable plastics, or other flexible material may be used. Billowing or flapping of plastic or flexible side covering in excess of 6 inches in any one place will not be permitted. Units open on both sides, such as used for temporary schools, warehouses, offices, etc., may be moved empty with no side covering.

Scales and Inspection Facilities

Every driver of an extra legal vehicle when operating on a city highway shall be subject to CVC 2813 and stop at all operational scales and inspection facilities.

Tow Cars

Disabled legal vehicles or legal combination of vehicles may be towed on City highways to the nearest appropriate place to repair, or to the nearest secure storage area that is appropriate for the vehicle or load, whichever is closest and most accessible. It is not the intent of this permit to allow these vehicles to be towed to their ultimate destination for convenience, unless that destination meets the above criteria. Disabled legal vehicles or combination of vehicles, when connected to a tow car, the drive axles, the tow car and/or the drive axle or axles of the disabled vehicle may exceed legal axle or axle group weight limitations. If any axle or axle group exceeds legal weight, movement is limited to the approved city truck route(s) or a route approved by the City Traffic Engineer.

Towing Permit Leads and/or Vehicles

Disabled vehicles or combination of vehicles whose movement is authorized by a transportation permit or any disabled vehicle or combination of vehicles, which because of damage has incurred distortion in width or height thereby causing an excess in legal dimensions may only be moved at the direction of a peace officer or single trip permit issued by the City of Orange.
