Abstract: A knockover roadway marker post has a base fixable to the ground by means of a stake or the like and having a flat upper surface provided with an upwardly tapering prismatic formation with a non-regular polygonal cross-section at its base. An upright post element comprises an outer reflector-carrying tube snugly fitted over an insert forming at the lower end of the outer tube a downwardly open recess which is congruent to and fittable over the formation of the base with the lower end of the post engaging the flat upper surface of the base around the formation thereof. A tension spring is hooked between the apex of the upwardly tapering formation and the upper end of the insert and is constantly under tension so as to pull the upper post part tightly down onto the base, and to return it to this position should it be knocked over.
