I am a British English native speaker, and I've heard a few references in American media to broadcasts of "x (typically traffic) on the 2s". Google does not reveal any useful information on exactly what this phrase is meant to mean, so I'm hoping an American English speaker can clarify for mine and the internet's sake.
I have a few theories:
- Traffic (or news or whatever) reports hourly at 2 or 22 minutes past the hour, or every two hours, or at 2AM and 2PM daily, or at 22:00 daily
- Television affiliates with a number two in their title using the title of the broadcast as a way to push their brand
- Traffic reports in reference to a specific route/interstate matching, both of which bearing the designator of #2
