Can 2.16.840.1.113883.3.2966.0.1 potentially be a valid Object Identifier (OID)? A colleague told me that zeros aren't allowed in arcs after the first, however I can't find any documentation on that. A reference to a definitive specification would be greatly appreciated.

Yes, a zero value in arc is totally allowed. I don't know why your colleague said it isn't. See an ISO 2022 Character Set Switching standard which has zero-valued arc in the middle and in the end
And here is a binary encoding (in hex) of your provided OID:
06 0C 60 86 48 01 86 F9 5B 03 97 16 00 01
it is perfectly valid.

Zero arcs in OIDs are definitely allowed. Valid OIDs values are governed by the Rec. ITU-T X.660 and X.670 series of recommendations and ISO/IEC 9834 series of international standards. Indeed if the first arc is 1 (iso) and second arc is 0 (standard), the third arc should be the number of the International Standard published by ISO or IEC.
