The present invention provides a device for displaying hazard indicia, having a stanchion defining a first end and a second end, whereby the first end defines a first cross section that is smaller than a second cross section of the second end; a base adapted to removably receive the second end of the stanchion so as to maintain the stanchion in a vertical position; and a means for allowing the device to be collinearly stacked on top of a second device such that only the second end of the device and the second end of the second device contact.

A Traffic Handheld Control Warning Sign including a first and second display sign which are fastened together and have the capability to display different traffic control warnings and commands simultaneously. The invention is battery powered and can be controlled by a separate or built in remote control. The invention can be hand held or can be used hands free by placing it in a tripod or pole and operating it with a remote control from a distance of up to 40 meters.

A self-propelled warning device used for road safety includes a bracket, a warning sign mounted to an upper side of the bracket, and at least one driving mechanism. The driving mechanism includes a supporting leg, a driving unit, and a wheel. The supporting leg includes a receiving portion, the receiving portion defines an accommodating space. The driving unit is accommodated in the accommodating space. The wheel is mounted on the receiving portion and is drivingly connected to the driving unit. The wheel is driven by friction of the driving unit. The driving mechanism is also disclosed.

A remote-controlled warning system embodying a light emitting device is provided. The systemic device may include an elongated member providing first and second pluralities of light-emitting outputs oriented in opposing directions, respectively. The elongated member extends from a conic base for increased visibility. Having a microprocessor configured to operate the first and second pluralities of light-emitting outputs at different intensities and patterns through a remote control raises the awareness of motorist beyond the immediate vicinity of the unsafe driving conditions.

Disclosed is a concrete block, preferably made of fiber-reinforced concrete, including a body and anchor intended for lifting the block. The anchor is secured to the body and arranged in blind cavities without protruding out of these cavities, particularly arranged at the level of one of the faces of the body of the block such as the upper face of the block when the block is in the installed position on the ground. The body includes reservations and/or attachment/association components, the reservations and the attachment/association component being intended for attaching, preferably removably, or associating, technical equipment that is to be associated with the block. The concrete block is intended to constitute an access-denial bollard and, as a secondary function, a block for supporting and to which to fix technical equipment.
