Question:
I never did get a chance to check back to what the answer was on when you had to have a tanker endorsement for a CDL. Will you enlighten me please.
Answer:
Ok since John Q seems to be absent does anyone else know the actual answer to that question he posed about the tanker? I was just curious.
Answer:
either a permanant liquid or gas tank or a portable with a rated capacity of 1,000 gallons or more.
BTW, dry bulks are not tanks.

Answer:
The answer was covered in detail, however since the old topics are gone and CJ has some misconceptions we will cover it again.
CJ says:

Under federal standards, this is the wrong answer.

In regard to CDL’s this is correct.

Notice the words in bold letters.

Cargo Tanks
Portable Tanks
Part 171

If a cargo tank is mounted in the back of a truck such as a 550 gallon water tank and a CDL is required the driver would be required to have a “N” or “X” endorsement for any tank over 119 gallons."If men were angels...No government would be necessary."
