Answer 1

The white markings painted on the pavement before railroad crossings typically consist of a large 'X' with the letters 'RR' and are designed to alert drivers to stop.

Step-by-step explanation:

The white markings painted on the pavement before crossings, such as railroad crossings, are known as 'Stop Lines' or 'Stop Markings'. These markings, which can be a large 'X' with the letters 'RR' to symbolize a railroad crossing, are designed to warn drivers of the need to stop before the tracks when a train is approaching. They serve an essential purpose in traffic safety by increasing the visibility of the crossing and providing a clear visual cue that drivers should prepare to halt.
