(WHTM) — Campaign signs are a popular way for candidates and voters to boost awareness and show support within communities, but PennDOT has guidelines for where they should go and when they should be taken down.

PennDOT says they are responsible for removing signs within the highway right-of-way. In that case, they will send a removal notice and hold signs for at least 30 days for retrieval.

Many municipalities have ordinances regarding removal timelines. In Harrisburg, political signs shouldn’t be placed on a lot for 60 days before the election and should be removed seven days after, according to the City of Harrisburg.

In Lancaster County, political signs should be removed one day after an election, and York and Lebanon County residents should remove their signs within 14 days.

In Berks County, some communities, like Fleetwood and Maidencreek Township, require signs to be removed within a week. Longswamp Township near Topton requires signs be removed “one hour after closing of polls.”

According to PennDOT, the public should not place any sign on PennDOT’s right-of-way as political signs near the highway may cause a distraction to motorists.

For candidates with signs placed around the region, it’s best to check with your municipality to find out how soon you have to collect your signs.
