A safety net that includes at least one illuminating element. The safety net is intended to be stored in a rolled-up fashion (similar to a roll-up window shade) in the trunk of a vehicle. When illuminated, the safety net provides a completely new and unique means of alerting oncoming traffic to a road hazard or other situation requiring traffic control. The safety net provides a warning means that will not be knocked over by the wind, as wind blows freely through the voids of the net. In addition, the safety net screens the scene from the view of those in oncoming traffic. The device may include a solid state controller that provides a variety of patterns or symbols to further enhance the visual safety features of the device. This can be accomplished by placing fiber optic strands in the net voids, or within the side illuminating fiber optic conduit itself.
