Abstract
A vehicle (10) carries an ejector means (17) which is mounted for reciprocating movement on the vehicle and is operable to eject discrete blobs of a viscous road marking material onto a road surface to be marked. The ejection means is arranged to move relative to the vehicle during ejection of the blobs so that its outlet moves at approximately the same speed as the vehicle and in the opposite direction, the arrangement being such that the speed of the blob relative to the roadway is approximately zero.
