Wondering why I had 2 small trucks pass by me during my run this morning, and they were loud and smelled bad. For about 10 seconds I could clearly see my breath while running. Does this happen with heavy exhaust or was I breathing something potentially harmful? It was slightly concerning.
Mostly just curious since I’ve been a runner for a long time and have never had this happen despite trucks and cars passing by me all the freaking time.

This may have been caused by the soot emitted by the trucks providing nucleation sites for water to condense. Your breath added extra humidity to the air and the soot could have seeded small clouds as a result.
