Running on empty means continuing despite exhaustion, depleted resources, emotional numbness, or lack of fuel. In poetry, the idiom is valuable for modern life, caregiving, grief, illness, overwork, poverty, and creative burnout. The vehicle image suggests forward motion without adequate power, making survival feel mechanical and precarious. A speaker may still move, speak, or serve while inwardly spent. Poets can use it to honour endurance while revealing the danger of systems that demand motion after vitality is gone.

Running on empty means continuing despite depleted energy, resources, hope, or emotional strength. The phrase comes from fuel gauges and vehicle travel, giving exhaustion a modern mechanical image. In poetry, it suits burnout, poverty, caregiving, grief, creative block, and long journeys. Students should notice that movement continues, but unsustainably. It pairs well with roads, engines, night driving, dry tanks, and the courage or danger of going on.
