General intrastate operations

See the Michigan Vehicle Code (MVC) for complete rules on intrastate operations.

  • A vehicle shall not be operated unless it is so constructed or loaded to prevent it's contents from dropping, sifting, leaking, blowing off or escaping from the vehicle
  • The load shall either be:
    • Covered with firmly secured canvas or similar devices of covering (tarp), or
    • Secured to the body or frame with adequate binders of adequate strength
  • Logs or tubular products must conform to the rules found in the MVC
General intrastate and interstate operations
  • Each CMV transporting cargo must be loaded and equipped to prevent the cargo from leaking, spilling, blowing off or falling from the motor vehicle
  • Cargo must be contained, immobilized or secured to prevent shifting upon the vehicle to the extent that the vehicle's stability or maneuverability is not adversely affected
Intrastate and interstate operations - general tiedown devices
  • All devices and systems used must meet the performance criteria of FMCSR, Part 393.102
  • All vehicle structures, systems, parts and components used to secure cargo must be in proper working order when used to perform that function with no damaged or weakened components that will adversely affect their performance:
    • This includes reducing the working load limit and not having any cracks or cuts
  • Repairs must comply with applicable standards of 393.104 or the manufacturer's standard
  • Tiedowns must be attached and secured in a manner to prevent them from unfastening, opening, releasing or becoming loose
  • Tiedowns and other components must be located inboard of the rub rails whenever practicable
  • Vehicle structures and anchor points must meet the performance criteria of FMCSR, Part 393.102
  • Materials used as dunnage or dunnage bags, chocks, cradles or shoring bars must not have damage or defects which would compromise the effectiveness of the securement system
  • The aggregate working load limit (WLL) of the securement system must meet or exceed half the weight of the article or group of articles (See FMCSR, Part 393.106(d) for complete explanation)
  • Tiedowns not marked by the manufacturer with a WLL will be given the WLL found in FMCSR, part 393.108
Intrastate and interstate operations - general length
  • When an article is not blocked or positioned to prevent forward movement, it must be secured by at least:
    • One tiedown for articles 5 feet or less in length and 1,100 pounds or less in weight
    • Two tiedowns if the article is:
      • 5 feet or less in length and more than 1,100 pounds in weight, or
      • Longer than 5 feet but less than 10 feet regardless of weight
    • Two tiedowns if the article is longer than 10 feet, and one additional tiedown for each 10 feet of article length, or fraction thereof, beyond the first 10 feet
  • When the article is blocked or braced to prevent forward movement, it must be secured by at least one tiedown for each 10 feet of article length or fraction thereof
  • Some cargo securement rules do not apply to "special purpose vehicles". See the FMCSR for complete information.
  • Tiedowns must be adjustable so the driver of an in-transit CMV can tighten them
  • Front-end structures , if used, must meet the criteria found in FMCSR, Part 393.114
