What does the W-002L 'Side Road - Left' sign mean?

What action should I take when I see the W-002L sign?

When you see the W-002L sign, you should immediately reduce your speed and increase your scanning of the road ahead and to your left. Be prepared to yield to any traffic coming from the side road, as they may not see you or may be entering the road without yielding to you.
