The lozenge (technically a mascle) can be used on public roadways in the United States and Canada to mark a specific lane for a particular use. The lane will usually be painted with a lozenge at a regular interval, and signage will be installed to indicate the restrictions on using the lane. This marking is most often used to denote [[high-occupancy vehicle lane]]s or [[bus lane]]s, with accompanying signage reading "◊ HOV LANE" or "◊ BUS LANE" and giving the requirements for a vehicle to be accepted. Prior to 17 January 2006, lozenges could also be used to mark bicycle-only lanes, often in conjunction with a bicycle icon.<ref>{{cite web |url=https://mutcd.fhwa.dot.gov/htm/2009r1r2/intro/intro.htm#tableI02 |title=Introduction - MUTCD 2009 Edition - FHWA |publisher=[[United States Department of Transportation]] |access-date=2018-05-20}}</ref>

In many parts of Europe, [[Priority to the right|traffic from the right has right of way]] at all junctions, unless otherwise stipulated. A yellow lozenge is used (typically on major routes) to indicate that the rule does not apply to the current route.

A hollow lozenge is also used in the signage of waterways{{where|date=November 2020}} to identify a hazard. A cross is placed in the lozenge, dividing it in four, to mark a restricted area.<ref>{{cite web |url=http://www.marine-movers.com/AidsToNavigationExplained.html |title=Aids to Navigation Explained |website=marine-movers.com |archive-url=https://web.archive.org/web/20170727015122/http://www.marine-movers.com/AidsToNavigationExplained.html |archive-date=2017-07-27|url-status=dead}}</ref>{{Clear}}
