Combination Curve and Side Road (Left)

Alerts drivers that the road curves to the left and that a side road intersects from the right within the curve. Watch for vehicles entering or crossing your path inside the curve, where sight distance and lane position are already compromised. Reduce speed and stay in your lane.
