Question from the HazMat transportation community (01.13.17):

Is it stated anywhere that the placards have to be mounted to the vehicle? If I’m carrying job site bulk tanks on a high flat can the tanks be visibly placard on 2 sides and front and rear or do placards need to be mounted on sides and rear and front of high flat?

My reply that same day:

Thank you for contacting me.

The quick answer is that as long as the placards are visible on all four sides of the vehicle it is not necessary to placard the vehicle as well.

I hope this helps.

Please don’t hesitate to contact me with any other questions.
