wondering if I need dot numbers.

That would be a commercial vehicle

 

A cargo van for an HVAC company is technically a commercial vehicle yet they don't need DOT numbers.

 

maybe,
1. if you transport passengers or haul cargo across state lines then yes,
2. If you transport hazardous materials that require a safety permit, you must also register for a number.
3. [h=2]State Requirements[/h]

• These states require every trucker to have a DOT number before entering the state: Alabama, Alaska, Arizona, Colorado, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, New York, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Washington, West Virginia, Wisconsin and Wyoming
  
  

 

I have the same setup, bar the chlorine.
Would chlorine be class 8 hazmat, and require placards?

 

You need a tanker and hazmat endorsment. I was thinking a ton truck and up had to have dot numbers. But the weight of your trailer is going to exceed 10,000 pounds with 800 gallons of liquid.

 

GVW over 26,000, pulling trainer over 10,000, read the rules. Your local DMV will have them for you.

 

well the reportable quanity for the table 8 is 1001

 

Hey now as a trainer I may be a little chunky but come on
