Updates to Regulations in DE, GA and NM concerning Tandem Axle Spreads

During a regular review of data, if was found that some spread axle dimensions and weights were not correct on the website. Changes were made to Delaware, Georgia, and New Mexico.


Code can be found here: https://delcode.delaware.gov/title21/c045/index.shtml

As it applies to Non-Interstate roads in Delaware, there are three axle classifications that must be followed:

  • Spread less than 40″ – 20,000 lbs
  • Spread not less than 40″ and equal to or less than 96″ – 36,000 lbs
  • Spread exceeds 96″ (count as 2 single axles) – 22,400 lbs


Updated the measurements to accurately depict what the code says: https://law.justia.com/codes/georgia/2018/title-32/chapter-6/article-2/section-32-6-26/

(5) “Tandem axle” means two or more consecutive axles, excluding the steering axle, which extend across the full width of the vehicle and whose centers may be included between parallel vertical planes spaced more than 40 inches apart but not more than 216 inches apart. (216″ = 18′)
