Frequently Asked Questions
Where can I place political signs?
You can place your signs anywhere so long as they are:
1) not in the highway right of way;
2) not in a location that poses a safety hazard (e.g. blocking sight to a driveway); and
3) placed with the landowner’s permission.

It also doesn't appear as if there's a disclosure statement on the sign, which is required by Texas law.
