Morphology
The phrase literally combines 'collision' (a clash) with 'course' (a route or heading) and the preposition 'on' signals being in that state, so a learner who knows the constituent words can infer that something is heading toward a clash or serious trouble. This spatial/trajectory metaphor is direct and common across languages, making the overall meaning predictable to a B1 learner.
Etymology
On a collision course paints a clear picture: two people, groups, or vehicles are moving on the same course toward each other and are heading for a collision if nothing changes. That's why it means 'likely to result in conflict, disaster, or failure'.
