Do I need a Hazmat endorsment?

If you don't have HM on your CDL then your company won't give you a HM load.But if you're in doubt then ask your company.

 

I would ask your company just to be on the safe side.

 

You need placards at 1000 lbs. But it is iirrelevant. you said it is 330 lbs and that is about 40 gallons, so not even close to1000 either way.

 

then yes you do that is well over 1000 lbs

 

On further research motor oil is not hazmat, you can haul all you want

 

I believe used motor oil is classified is a hazardous waste material, which needs to be 1,001 lbs or more to require placards.

 

Lbs or gallons?

Lately I'm hauling HazMat and to go through the tunnels on the PA TPK materials I haul have to be in "Non-Bulk Packaging" which is less than 118 gallons or 884 lbs. per package

I don't have my table handy but I believe the used oil would be combustible, not flammable. Doesn't matter if it's less than 1000 lbs, but if the container holds 118 gals. or more, then you may need an endorsement and placards. You would need shipping papers to show what the material is and if the container holds more than the aforementioned gals., then how much exactly is in there? Follow?

You need to know what it is, how much there is and some docs from shipper. You can look up particulars online or get a handbook at your DMV. Hope this helps.
