Double trouble?

If you're ALREADY pulling twins you really should know your specs on your set.

A pup is 28'
Two of them are 56'
Add your dolly and your cab and you're easily 75-82ft + depending upon day cab or sleeper cab.

Some routes are restricted to single combination vehicles lengthwise but not to sets. I see this all the time.
The longer SINGLE trailer has a longer turning radius, while the set will follow closely like a train... thus often being allowed when a 53' is not.
What you described is opposite and is rare.. I suppose they have their reasons.

Rand McNally makes a book with road restrictions detailed in the front for all highways in a state. It will list weight, length, and clearance.
Don't trust that GPS or you'll not be driving as a pro for very long.
GET AN ATLAS.

Lots of municipalities will restrict HM routes.
It is vital that you take note of this.
They won't accept.. "I'm sorry".

As a general rule you can rely on 12k for your steers
17k for each axle.. 34k for a tandem.

States will sometimes allow a little more on a single axle than the 17k.

READ THE ATLAS STATE RESTRICTIONS AND GUIDELINES.

 

Steer 12.5k 20k per single axle. 34k tandems. 80k max unless you have a permit for overweight.

No tunnels for Haz. Read the signs it will tell you to go around on a belt route. GPS might not tell u crap might want to invest in a Truckstop atlas. I used that a lot when running OTR with Hazmat. It’s old school but the best way. Go to the wrong area and get a ticket will be very bad.

 

If you pull HazMat Google & bookmark the National HazMat Route Registry. It links to every state's HM restricted routes. BTW very, very few routes prohibit HM. Sevetal states have zero restrictions, while many states only have 1 or 2.

Beware of Arizona & Ohio if you pull HazMat & have PrePass. You still have to cross the scales, if they are open, regardless if PrePass green light. I think AZ fine is $600.

 

AZ PrePass means go in AZ.

 

Hmmmm. I asked bear at the scale house, and he told me follow signal lol.

 

no dont listen to him. get 4 cats,2 dogs, family size bags of chips, and 2 7" gps and cell phone holder. oh and 4 outward and inward facing cameras. 3 94oz truckers mugs with free refills at pilot,loves. when you have spent your whole paycheck and used all your points. Then place all of the above items on the windshield and dash. then create a youtube channel and make trucker videos.
