2 years ago, a flatbed driver would have said the same thing about the tanker endorsement...."I just bought a flatbed and will NEVER pull tankers, why get the endorsement??"
Not saying triples are needed, or ever will be. But with this govt, lord only knows
Doubles and triples are the same endorsement. If your license says you can pull doubles, you can pull triples anyplace its legal. There is no separate triples endorsement.
