Other Important Rules
Polling Places
No political advertising on public property within 250 feet of the entrance to a voting place on Election Day (21-A M.R.S. §682).
Removing Signs
Taking, defacing, or disturbing a properly placed temporary sign is a civil violation with a fine up to $250
(23 M.R.S. §1917-B).
Noncompliance
MaineDOT (and municipalities in urban compact areas) may remove non-compliant signs. Signs that create hazards are removed regardless of other compliance.
Cemeteries
Though not a rule, out of respect, place no signs in graveyards or on roadsides abutting them.
Best Practice
Whenever possible, place signs on private property outside the right-of-way. Always label every sign with the required information and the date. When in doubt about the right-of-way line, contact your local MaineDOT region office.
