The present invention provides an advance warning traffic safety device for warning pedestrians, members of a road work crew, and other persons adjacent a road that a vehicle has strayed from the proper traffic path on the road and may endanger such persons. The advance warning safety device provides an audible alarm which serves as an advance warning to such persons downroad of the traffic safety device. The traffic safety device includes a pressurized fluid container for supplying compressed air to a plurality of horns in response to a vehicle collision with the traffic safety device. An initiator mechanism for initiating the audible alarm includes a frangible gas cap which prevents release of the compressed air to the horns until broken by a plunger-type component, which is moved into glass or other breakable materials breaking contact with the cap by a pendulum device which pivots in response to displacement of the traffic safety device from its generally free standing position adjacent the road in response to a vehicle collision with the traffic safety device.
