No Entry Sign with Person Ducking - Clearance Warning Symbol #1982759 (License: Personal Use)

The image shows a modified prohibition sign: a standard red oval with a white horizontal bar (indicating “no entry”), overlaid with a black stick figure crouching beneath the bar, suggesting insufficient vertical clearance. The design conveys both access restriction and physical hazard, commonly used in tunnels, garages, or industrial zones where height limits apply. The high-contrast colors ensure visibility and immediate recognition.

Used on roadways, parking garages, warehouses, or construction sites to warn of low-clearance hazards or restricted entry; matches user intent for safety compliance, traffic regulation, or facility navigation guidance.
