- (a) a detector mounted at a detection location required to be passed by the vehicle before reaching the service location and at an elevated level selected so as to be able to detect any vehicle of a height in excess of said clearance and to actuate an associated switch in response thereto;
(b) first signalling means dependent on actuation of said switch and operative to produce a first selected signal perceptible by the driver of the vehicle at a location prior to reaching the said service location to warn the driver of an overheight condition when so detected;
(c) second signalling means dependent on actuation of said switch and operative to produce a second selected signal at said service location perceptible to said attendant to simultaneously warn said attendant of said overheight vehicle; and
