Sample question from test 4
signs
At a highway-railroad grade crossing, what does the pictured white crossbuck sign identify?
- The crossing itself, where a train requires you to stop until the intersection is clear
- A railroad crossing far ahead where stopping is never needed
- A school crossing controlled by a patrol
- A work zone where only construction vehicles may enter
Answer: The crossing itself, where a train requires you to stop until the intersection is clear. The white X-shaped crossbuck is located at the highway-railroad grade crossing itself. If a train or railroad vehicle is approaching the intersection, the driver must stop behind the stop line or before the intersection and wait until it is clear. The round yellow RXR sign serves as the advance warning farther up the road. Do not treat the crossbuck as a school or construction marker. See the X, search for rail traffic, and be ready to stop.
