Retroreflective yellow lines outlined with yellow or orange rectangular flags on a taxiway indicate what?

Hazardous area boundaries on taxiways are marked with retroreflective yellow lines outlined by yellow or orange rectangular flags. This signaling shows the limit of a work zone or other temporary hazard, and pilots or ground vehicles should not enter beyond it unless explicit clearance is given. The retroreflective property helps visibility at night, making the boundary clear from a distance. This differs from no-entry signs or barriers, which use different indicators; hold positions are shown with specific hold-short markings, and an emergency lane has its own dedicated markings.
