Anything of this nature will require special ALDOT approval. Detailed drawings will be required and need to include shop drawings of the item being shipped, the truck, and trailer axle weights and spacings for both truck tractor and trailer. A letter from the manufacturer is required to certify the shipment is reduced to the lowest possible size and weight configuration and explain why it can not be shipped by other means, such as by barge or port. Loads exceeding 150,000 pounds (68038.8 kilograms)are subject to a full-scale structural bridge analysis if bridges are along the route. In addition, a special weight authorization (SWA) is required from the permit office to initiate the necessary bridge rating section investigation. Night travel (9 PM – 6 AM) may be required with a state trooper or police escort (minimum of 2 when traveling). A route survey will probably be required. The Alabama State Troopers Association handles all police/trooper escorts scheduling after issuing your super load permit. A lighting system configured from strobe warning lights must be placed on each extremity of the shipment in addition to basic requirements such as flags and oversize load signs. All railroad crossings have to be identified, and the railroad notified of the date and time you intend to cross. ALDOT will more than likely verify this with the railroad and not issue a super load permit until verified. It’s the carrier’s responsibility to notify the railroad of each intended crossing. You will find a small plaque with a phone number and a “crossing number” that identifies each crossing for submitting cross requests at each rail crossing. A bucket truck is required to accompany loads that exceed 16 feet and 5 inches (5.0 meters) in height, and it’s the carrier’s responsibility to show proof of “utility notification” for shipments above 16 feet and 6 inches (5.02 meters) in height. City or county approval is required for Alabama super loads as well.

    1. The state requires your load to be accompanied by escort vehicles when it’s above certain dimensions to guarantee its safety and that of other motorists. Escort vehicles are the eyes of truck drives when shipping oversize loads exceeding the legal dimensions.

  1. So you’re saying if I bought a center console boat that was over 8’6” but less then 12’ wide I wouldn’t be able to tow it to the beach on Friday and come home Sunday night? Most center console boats that are 23’ or over are already 9’ beam and to leave them at a wet slip dock is like over $500 a month. That’s crazy. Boats with a beam of no more than 12’ should get an exemption like RVs do.

    1. Anything over 8’6″ in width requires a permit. You are only permitted to move during the specified hours on this (Florida) page. Always refer to your permit before moving as travel times may be modified.

      1. Could you please further explain your question please? At the moment we have not heard about any laws that involve measuring “wind” speeds and have assumed this up to the discretion of the driver. We’ll be happy to further research it for you but want to make certain we clearly understand the question. Thank you for your time.

  2. What are the calculations for oversized loads on steep mountain grade roads for rate of speed and time to stop at a red light placed at bottom of steep grade? What should the length of a yellow light? What type of safety notifications for changing lights are required?

    1. Well, firstly pardon the delay as you got caught in a huge amount of posting spam. However once cleared out, there you were Dr. Richards. So, to be direct as possible this is a pretty isolated incident however does occur. So, “oversize” wouldn’t have a huge effect on the capabilities of the vehicle to stop. However, weight would. And this is yet another reason besides creating stress cracks in roads that extra axels are required in most of the world in order to be eligible to ship heavy haul items (in NA over 80,000 lbs GVW). With the extra axels you get that many more brake pads and shoes as well. Any experienced driver which is usually what it takes to set behind the wheel of something so drastically expensive (some over 1 mil overall) would know what speed to take the approach with which would probably be very slow. The brakes combined with the axles are designed to accommodate the maximum weight allowed on the trailer so failure would be an extreme. In certain circumstances either the state would require or the carrier may request a traffic control officer at the light. In the event one was not requested or required the driver would simply call a yellow (and probably even a green) light a red one and come to a complete stop before continuing. Yet another reason newbies drive $100,000 rigs and heavy haul drivers are well seasoned with most over 20-30 years in the industry. It’s a pecking order that is determined by either how much money you have saved (which takes a lot of years) or how much verifiable experience you have as word of mouth probably couldn’t get you in the passenger seat let alone behind the wheel. I hope this helps you.
