A traffic sensing alarm assembly includes a motion sensing unit that emits a focused beam of electromagnetic energy to detect a vehicle that passes through the focused beam. The motion sensing unit broadcasts an alert signal when the focused beam is interrupted. A first mount is removably attachable to the motion sensing unit to engage an edge of a road sign. A second mount is removably attachable to the motion sensing unit to rest on a dashboard of a service vehicle that is parked on a roadside. An attachment is removably coupled to the motion sensing unit to engage a rear view mirror on the service vehicle. A remote alert is worn on a service worker's clothing and the remote alert is in wireless communication with the motion sensing unit. The remote alert emits an audible alarm when the motion sensing unit broadcasts the alert signal to alert the service worker to the potential hazard of oncoming traffic.
