Match each standard warning sign description on the left with its correct hazard meaning and required driver response on the right.
- Yellow diamond sign displaying a red octagon symbol with a black arrow pointing upward above itStop Ahead (W3-1): Prepare to decelerate and come to a complete stop at an upcoming regulatory control sign.
- Fluorescent yellow-green diamond sign depicting a walking human silhouettePedestrian Crossing (W11-2): Watch for pedestrians and yield the right-of-way at crosswalks ahead.
- Yellow diamond sign showing a straight vertical lane line on the left and a right lane line slanting inwardRight Lane Ends (W4-2): Prepare to merge left as the right lane terminates ahead.
- Yellow diamond sign depicting a vehicle tilted sideways with its right wheels lower than its left wheelsUneven / Low Shoulder (W8-9): Exercise caution along pavement edges to prevent steering control loss if tires drop off.
Answer
The standard yellow warning signs correspond to their actions as follows: Red octagon with upward arrow matches Stop Ahead (W3-1); Walking human silhouette matches Pedestrian Crossing (W11-2); Straight left line with inward slanting right line matches Right Lane Ends (W4-2); Car tilted sideways on an edge drop matches Uneven / Low Shoulder (W8-9).
Each matching pair accurately reflects MUTCD standard warning sign symbols: the red octagon arrow symbol indicates an upcoming Stop sign requiring advance deceleration; the walking pedestrian silhouette indicates crossing zones requiring driver vigilance and yielding; the slanting right line indicates a lane reduction requiring a timely merge; and the tilted vehicle graphic warns of a drop-off between pavement and shoulder requiring steady wheel control.
