Sign post ftg above frost line
(OP)
I have designed a sign post footing 12inch dia concrete and 3 feet deep. Frost line is 6.5 feet deep. Can I ignore it here?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Have you thought about a 6.5' deep caisson instead? This tends to be cheaper.

If so, I would be a bit careful. It is often recommended not to count on passive resistance of soil in the frost zone as the freeze/thaw action tends to break the soil up, particulalrly when subjected to cyclic loads.
JMHO.
