The route serves to connect Oshawa, Whitby, Ajax and Pickering along Highway 2 to the Toronto district of Scarborough and Yorkdale Bus Terminal in the Toronto district of North York, as opposed to sister route 96 operating express service along Highway 401 to Finch Bus Terminal in North York.
Additionally, the route serves to connect passengers at the Scarborough Centre Bus Terminal in Scarborough to route 96 or 98 buses for westward travel towards Finch Bus Terminal, or from route 96 and 98 buses for westward travel to Yorkdale Bus Terminal.
This route operates primarily on Highway 2 and Highway 401.
The 92 Oshawa-Yorkdale route operates from the Oshawa Bus Terminal to the Yorkdale Bus Terminal, making stops along Highway 2 in Whitby, Ajax and Pickering, as well as the Scarborough Centre Bus Terminal and the York Mills Bus Terminal.
On June 29, 2013, Durham Region Transit's route 900 DRT PULSE Highway 2 was introduced. Thus, GO Transit routes 94 and 95 were discontinued to avoid duplicating service along Highway 2 in Durham Region. To maintain service connecting Highway 2 to Yorkdale Bus Terminal, route 92 was introduced. Meanwhile, route 98 Pickering-Finch was also introduced as a weekday peak service to connect passengers along Highway 2 (via route 92) and in Pickering to the Finch Bus Terminal via connection at the Scarborough Centre Bus Terminal. Service along route 96 Oshawa-Finch Express was also expanded to provided all day, two-way express service between the GO stations and the Finch Bus Terminal, making it the first GO bus route to operate to the terminal on weekends.
