Question

Difficulty: MediumWarning Signs

Match each standard yellow warning sign description on the left with its correct hazard meaning and required driver action on the right.

  • Yellow diamond sign with top and bottom arrows pointing inward toward a dimension clearance measurementWarns of an overhead structure with limited vertical height; drivers of tall vehicles must verify clearance before proceeding.
  • Yellow diamond sign showing two opposing traffic arrows split by a median barrier symbol at the topWarns that a multi-lane highway separated by a physical island begins ahead; drivers must keep to the right side of the divider.
  • Yellow diamond sign featuring a black silhouette of a person walking between parallel line markingsWarns of an upcoming pedestrian crosswalk area; drivers should reduce speed and prepare to yield to individuals crossing.
  • Yellow diamond sign showing a main vertical arrow next to a curving entry line that forms its own parallel laneWarns that entering traffic forms a new separate lane alongside existing traffic; immediate merging is not necessary, but drivers should remain alert for lane shifts.

Answer

1. The yellow diamond sign with inward vertical dimension arrows matches the warning for an overhead structure with limited vertical height (Low Clearance).
2. The yellow diamond sign with opposing arrows separated by a median symbol matches the warning for the start of a divided highway requiring vehicles to keep right.
3. The yellow diamond sign displaying a walking figure matches the advance warning for a pedestrian crosswalk requiring reduced speed and yielding.
4. The yellow diamond sign with a main arrow alongside a separate entering path matches the warning for an added lane where entering traffic gets its own dedicated lane.
Each yellow diamond warning sign alerts drivers to specific hazards ahead. Low clearance signs indicate vertical overhead limits. Divided highway signs inform drivers of upcoming physical medians. Pedestrian crossing signs alert drivers to look out for pedestrians and yield. Added lane signs inform drivers that merging is not required because a new lane opens for entering traffic.

Step-by-Step Solution

1
Analyze the symbol of inward-pointing arrows around numbers.
Identify this as MUTCD W12-2 (Low Clearance), which measures vertical height under structures.
Top and bottom arrows pointing toward a numeric value warn drivers of overhead obstructions.
2
Analyze the symbol showing two opposing arrows separated by a physical median section.
Identify this as MUTCD W6-1 (Divided Highway Begins).
The median island symbol at the top indicates that the roadway is splitting into a divided highway.
3
Analyze the symbol depicting a person walking between lines.
Identify this as MUTCD W11-2 (Pedestrian Crossing).
Yellow warning diamond signs with pedestrian figures warn drivers to watch for people crossing the street.
4
Analyze the symbol showing a main arrow next to a parallel entering arrow without a merge junction point.
Identify this as MUTCD W4-3 (Added Lane).
An added lane sign indicates entering traffic does not need to merge immediately because a new lane begins.
