Morphology

collision + course

The phrase combines 'collision' (a clash) with 'course' (a route or heading), so the sense 'a path or situation likely to lead to a clash or crash' is directly inferable from the constituents. This compositional pattern is a transparent metaphor (route → heading toward) and is cross-linguistically common, so a B1 learner who knows the component words should be able to understand it.

Etymology

Collision course comes from ships and planes: when two ships or planes are on a path that will make them crash, a collision means a crash and a course is the path they follow. So we now say two people, teams, or plans are 'on a collision course' when they are likely to clash or cause a big problem.
