A Safety Warning Device which when the visual tape and laser mechanisms are components of vertical posts (both primary and corresponding), can be mounted to a base (permanent or portable) or customized to fit on a flatbed trailer, which when the visual tape is extended and the laser mechanism is activated provides both an audible and visual warning, notifying person(s) when they are in danger or in a restricted/unauthorized area. The tape is a visual warning which is high enough to be seen by person(s). The height can be adjusted on both the primary and corresponding posts. The laser is both a visual warning (as the light/laser beam is visible) and an audible warning when the laser connection is disturbed or interrupted. This can be an immediate warning as well as a signal sent to an alternative warning mechanism.
