Sample question from test 4
signs
What hazard does the round yellow RXR warning sign announce?
- A railroad crossing ahead where a stop may be necessary
- A circular intersection with traffic entering from the left
- A bicycle route that crosses the roadway
- A reduced speed zone ending immediately
Answer: A railroad crossing ahead where a stop may be necessary. The round yellow RXR symbol is an advance warning for railroad tracks ahead. It gives the driver time to reduce speed, look for trains, and prepare to stop if the crossing controls or train require it. The second choice confuses the round shape with a roundabout, but the RXR letters identify rail service. Begin scanning before reaching the tracks, and avoid stopping on them or entering when the roadway beyond cannot hold the vehicle.
