- Circular yellow sign featuring a black 'X' and the letters 'RR'Warns of an upcoming railroad crossing; drivers must prepare to yield or stop if a train is approaching.
- Yellow rectangular sign with a bold black arrowhead chevron patternWarns of an upcoming sharp change in road alignment; drivers must reduce speed and navigate the curve safely.
- Yellow diamond sign depicting a broad vertical arrow joined by a sloping side arrowWarns that traffic from an entering lane is joining the main roadway; drivers should adjust speed or position to facilitate safe entry.
Answer
The yellow pennant sign matches the No Passing Zone warning; the circular yellow 'RR' sign matches the advance railroad crossing warning; the yellow chevron sign matches the sharp curve alignment warning; and the yellow diamond merge sign matches the converging traffic warning.
Each standard warning sign uses distinct geometry and color coding specified by the MUTCD. The yellow pennant is placed on the left side of the road to mark a No Passing Zone. The round yellow sign exclusively provides advance warning of railroad crossings. Chevron rectangles delineate sharp alignment changes around curves. The yellow diamond with converging arrows alerts drivers to incoming merging traffic.
