Abstract
A low profile snowplowable road marker and method of installation is disclosed. The snowplowable road marker has a circular dome section having a pair of deflectors which wrap/encircle a signalling device along a circumferential edge of the marker. The deflectors are separated by a gap to permit drainage. The deflectors have wedge shaped ends to lift the snowplow over the signalling device. The circumferential edge is radiused and mounted in a bore as to be below the level of the road surface.
