warning
Sounds like a warning of what Americans would call a railroad crossing ahead...
well the advantages of a school crossing is that you can get to the other side. But the disadvantages is that some cars don't stop at all.
Not really. A railroad intersection would be an example of two lines intersecting. An example of two planes intersecting would be the ground and the side of a building or the ground and the railroad crossing sign post.
Approximately 50% of railroad crossing crashes result from a vehicle colliding with the side of a train. These incidents often occur when drivers underestimate the speed of an approaching train or fail to notice warning signals. Safety measures, such as improved signage and public awareness campaigns, are crucial in reducing these types of accidents.
