The Minnesota Department of Transportation is reminding drivers of oversized loads and farm equipment to not to remove traffic signs placed at railroad crossings.

Signs that are removed so loads and equipment can clear the roadway and pass over the tracks pose a safety threat to other motorists, MnDOT said in a news release.

Signs at rail crossings may include a cross buck, stop signs and stop ahead signs.

The location of the signs are dependent on the width of the road crossing the railroad. They are offset from the edge of the traffic lane so they are off the roadway, but remain within the driver’s cone of vision, giving them both notification of the crossing and time to react, the release said.

Drivers of these loads and equipment should plan their route to avoid damaging signs and structures adjacent to the railroad.
