guide rails
Path-limiting safety bars
Guide rails are protective barriers along the edges of roads, bridges, or elevated paths, designed to prevent vehicles or pedestrians from going over the side.
In machinery, guide rails are tracks that direct movement along a fixed path.
Figuratively, guide rails are constraints that keep behavior or processes within acceptable bounds: The company put guide rails on employee spending.
Also spelled as one word: guardrails.
