Signal workers to move loaded cars.

“Signal workers to move loaded cars.” is a supplemental task performed by Loading and Moving Machine Operators, Underground Mining. Among the occupation's 28 rated tasks, workers place it 14th by importance (#15 most important). About 59% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.
