Match each standard warning sign symbol and shape description on the left with its precise hazard meaning and required driver action on the right.
- Yellow diamond sign depicting a black truck tilted at a 45-degree angleHigh vehicle rollover hazard on a ramp or sharp curve; drivers of high-center-of-gravity vehicles must reduce speed well below advisory limits.
- Fluorescent yellow-green pentagon sign depicting two pedestrians carrying books/bagsSchool zone or school crosswalk advance warning; drivers must reduce speed, exercise extreme caution, and prepare to stop for children.
- Yellow diamond sign displaying a black right-angle arrow with a 25 MPH supplementary plaqueSharp turn ahead in the roadway (90-degree bend); drivers must decelerate to the indicated advisory speed prior to entering the turn.
- Yellow diamond sign showing a vertical straight line on the left and a line angled inward on the rightRight lane reduction ahead; traffic in the ending right lane must merge safely into the continuous left lane.
Answer
Each warning sign description correctly pairs with its specific hazard and driver response: the tilted truck sign pairs with the rollover hazard warning; the pentagonal school sign pairs with school zone caution; the right-angle arrow with advisory speed pairs with the sharp turn warning; and the inward-curving line sign pairs with the right lane merge warning.
Each standard warning sign communicates a unique hazard through visual shape and symbol conventions established by the MUTCD. A tilted truck symbol specifically highlights rollover dangers on curves for vehicles with a high center of gravity. A pentagon-shaped sign is exclusively designated for school zones to alert drivers to children crossing. A right-angle arrow denotes a sharp 90-degree turn requiring deceleration to the advisory speed. Finally, an inward-slanted line on a lane sign warns drivers that the right lane is ending and requires merging.
