As safety lock for locking a pivot connection of an articulated vehicle for servicing, shipment, and the like, characterized by a sector disc means rigidly affixed to one section of the vehicle with engaging means such as notches or protrusions disposed about its periphery; and a lock member pivotally mounted on the other section of the vehicle and pivotal into a normal position out of contact with the sector disc means, into an armed position, and into a locked position. The operator can pivot the lock member into the armed position, where the lock member is in interference with the sector disc so as to be drawn into the locked position upon further steering in a predetermined direction. The operator may then operate from the operator's console the steering switch to effect the locked position, in which the lock member engages at least one of the engaging means in the sector disc. Also disclosed are specific preferred embodiments in which the lock member is movable in a plane parallel with the plane of the sector disc and has a holding pin for holding its free end in either the normal position or the locked position.
