Embodiments of safety trucks incorporate multiple connection points to which a variety of attachments, or combinations of attachments, can be releasably and interchangeably coupled to enable their use with increased effectiveness to safeguard roadway construction, maintenance and repair personnel as they perform tasks within or relatively near to roadway workzones and worksites. Also, methods of operation of the safety truck embodiments enhance their ability to guard and protect roadway construction, maintenance and repair personnel while they work within or relatively near to roadway workzone and worksite locations.

The present invention relates to a vehicle emergency safety device using a selfie stick, the device comprising: a support which comprises a plurality of poles with different diameters, including first, second, third, and fourth poles, wherein the poles are successively nested in the first pole with the largest diameter and withdrawn therefrom up to a desired length in a telescopic manner; two fixing brackets installed in the lower portion of the support; a joint part installed in the upper portion of the support; a cradle which is installed in the upper portion of the joint part and can be rotated 360 degrees by a second adjusting screw; and a flashing light inserted into and fixed to the cradle.

Portable traffic message signs configured for use on or near roadways, highways, sidewalks, and/or other travel routes. The portable traffic message sign may be configured to provide instructions, warnings, alerts, and/or other information for travelers. In some embodiments, the portable traffic message sign may be configured to be adaptive in response to sensed weather, traffic, and/or other conditions. For example, the portable traffic message sign may have a controller determining suitable message content to display, the message content reflecting a present traffic and/or weather condition. Moreover, the message sign controller may select, based on a speed of travel of traffic, words, phrases, and/or pages to display the message content such that the message may be perceivable by oncoming travelers. The controller may control height, angle of rotation, and/or other orientation parameters of the message sign toward a point of aim in order that the message may be perceivable by travelers.

A trailer-mounted system and apparatus are provided to improve safety at road construction sites and other locations by allowing drivers to be signaled, and one or more lanes of traffic blocked, without having a flagger stand in or immediately adjacent to a road that is carrying traffic. The system and apparatus may have extensive data and audio and video networking capabilities to allow for remote control of the system and/or observation of the construction site. These networking capabilities may allow the system to further serve to enhance collaboration among remote worksites.

A variant apparatus may be mounted on a highway divider such as a K-rail instead of a mobile trailer. Another variant provides a portable kiosk containing apparatus to supply the data networking and collaboration functions without the mechanical apparatus used to block traffic.

The safety tripod includes a tripod, a flight driving machine mounted on the tripod to enable the tripod to fly, a landing base for seating the tripod on the ground when the tripod lands, and a standing guide mounted on the tripod to enable the tripod to stand up.

A safety truck includes: an over-cab storage rack to store nested stacks of barrel-type safety barriers (traffic delineators); a man basket (safety module) mounted within an inset formed in a flat bed of the safety truck along the left or right side thereof to provide a support platform below the flat bed to enable personnel to ergonomically place the barrel-type safety barriers on a roadway; a sign cage mounted to the flat bed to store components of warning signs; a display board that includes speed detection radar to detect a speed of a vehicle approaching the safety truck, at least one display device to display a message readable from behind the safety truck, and a camera to capture an image of the approaching vehicle; and/or a truck-mounted attenuator (TMA) connected to the rear of the safety truck to absorb kinetic energy of the approaching vehicle colliding with the TMA.
