Which color is commonly used to indicate caution in safety signage?

• A. Yellow
• B. Red
• C. Blue
• D. Green

Answer: (A)

Yellow is used to indicate caution because it quickly signals you to slow down and be careful about a potential hazard. In safety signage, colors convey risk levels at a glance: red denotes danger or prohibition, blue signals a required action, and green shows a safe condition or exit. So a yellow sign tells you to proceed with awareness and take preventive precautions, such as watching for slippery floors or moving equipment.
