With bus bulbs or boarders, a [[bus]] can stay in its [[traffic lane]] to discharge and pick up passengers, instead of having to pull over to the curb.

The term bus bulb is prevalent in [[North America|North American]] usage, whilst bus boarder or bus border is used elsewhere.<ref name=tcrpr65-in>{{cite web | url = http://gulliver.trb.org/publications/tcrp/tcrp_rpt_65-a.pdf | title = Transit Cooperative Research Program Report 65, Evaluation of Bus Bulbs | publisher = Transportation Research Board | pages = 1 | year = 2001 | access-date = 18 April 2008 | archive-url = https://web.archive.org/web/20050501053556/http://gulliver.trb.org/publications/tcrp/tcrp_rpt_65-a.pdf | archive-date = 1 May 2005 | url-status = dead }}</ref><ref name=tflgaa>{{cite web | title = Accessible bus stop design guidance | url = http://www.tfl.gov.uk/cdn/static/cms/documents/accessibile-bus-stop-design-guidance.pdf | publisher = [[Transport for London]] | pages = 31–36 | year = 2006 | access-date = 18 April 2008}}</ref><ref>{{cite web | title = Buses | publisher = Auckland City Council | url = http://www.aucklandcity.govt.nz/auckland/Transport/buses/first.asp | access-date = 18 April 2008 | archive-url = https://web.archive.org/web/20080513162353/http://www.aucklandcity.govt.nz/auckland/transport/buses/first.asp | archive-date = 13 May 2008 | url-status = dead }}</ref>

A bus bulb or boarder can be considered as a specific form of [[curb extension]], although that term is more normally used to describe a sidewalk extension for the purposes of [[traffic calming]] or other [[Road traffic management|traffic management]] purposes.
