When running doubles the heavier trailer is in front BUT... what if the set is made for you and the lighter trailer is up front. In my scenario, there was only a 3000lb difference between the trailers so I took off with no issues. The question I have is... if a lighter trailer is in front, is there a DOT rule on the allowable maximum weight difference between the two trailers?

Been a while since I hooked a set, I want to say you have a 5% window? Someone else may correct me
Boulevard Thanks this. -
that 3,000 pound difference CAN BE the difference on snow, ice, wet roads, when that tail cracks like the whip it'll be.
you wanna face that?
i always read the bills, and checked the weights, and did the proper hook up. that always avoided any issues that "might arise" during the haul.
best thing to do is, NOT BE LAZY, and break them down, and set 'em up CORRECTLY.
then inform the dispatch, load supervisor, terminal manager, WHOMEVER that they were set up wrong.
at least, i valued my CDL that much to have done that.
but what do i know, after only a mere 48 years..??? -
Preferably you want the heavier up front. 3-4k lbs won't make a difference.
So long as axles scale out , you're fine.
Hope this helps.YardMule89, Boulevard, God prefers Diesels and 3 others Thank this. -
Just answer the question, like you were in the situation, without it going to an armageddon situation.
3K lbs difference in a hooked set ain't nothing to fret about - if it scales, roll.YardMule89, Trucker61016, Truckermania and 7 others Thank this. -
"Safety first" in this business, right ? 3000 should be ok heavier on rear trailer, I mean you can legally axle a 3000 difference between axle 4 and 5 on the same trailer, 17k axle 4 and 17k axle 5, or up to 20k axle 4 but only 14k axle 5 ( gross 34k 1 trailer)
