ABSTRACT:
A normally upstanding road marker including a conical body is provided with a special base formed of an elastomeric material for inducing self-righting movements to return the road marker to an upstanding position subsequent to its having been tipped over. The base is provided with a peripheral edge of undulatory configuration which allows the base to be large enough to induce the self-righting movements without being excessively heavy.
