Most European countries use sequential numbering schemes. Spain uses distance-based numbering on its Autovias, but not on its Autopistas. Austria, the Czech Republic, Hungary and Slovakia use distance-based schemes. A number of European countries (including the Netherlands, Belgium and France) do not number motorway intersections, apparently because one cannot "exit" the motorway there. Countries like Germany and Switzerland number interchanges, but instead of the usual exit symbol, they are given a specific interchange symbol.

Italy uses sequential numbering on the ring roads for some cities, including the ring road of Rome (''GRA'') and Milan (''Tangenziali''). At one time, it referred to junctions on the [[Autostrada del Sole]]<ref>{{Cite web|url=http://mryamamoto.50megs.com/Autostrada_del_sole.html|title=Autostrada Del Sole|access-date=2006-09-14|archive-url=https://archive.today/20060505011533/http://mryamamoto.50megs.com/Autostrada_del_sole.html|archive-date=2006-05-05|url-status=dead}}</ref> by number, and published same on toll tickets; though these may not have been posted on signs.

Both the United Kingdom and the Republic of Ireland use sequential numbering systems, with the junction number indicated by a white number in a black square in the corner of signs. In the United Kingdom they are frequently referenced in the media as the number with "J" on front of it, with for example Junction 58 being referred to as "J58"; as such this abbreviated term has entered popular usage. If a junction is newly constructed to between two existing junctions, it is normally allocated the number of the lower of the two junctions, with the letter "A" attached, followed by "B", then "C" (and so on). For example, a new junction opened between Junctions 86 and 87 would become Junction 86A, and if a new junction opened between Junctions 86A and 87, it would be Junction 86B.

In the Republic of Ireland, junction numbers have existed since the opening of the first section of the [[M50 motorway (Ireland)|M50 motorway]] in 1990.{{cn|date=February 2025}} Since 2005 have been given greater prominence on road signs. With the development of the [[Motorways in the Republic of Ireland#2000–2010|inter-urban motorway network in the 2000s]], the [[National Roads Authority]] adopted a numbering scheme for the inter-urban roads that saw Junction 1 be designated as that road's junction with the M50 in most cases.{{cn|date=February 2025}} This has meant renumbering of existing junctions on some motorways, most notably the [[M7 motorway (Ireland)|M7 motorway]]. Non-motorway dual carriageways forming part of major inter-urban roads also have junction numbers; however, only grade-separated interchanges are numbered.

Countries like Germany and Denmark do not number exits on single carriageway routes that are open only to motorised traffic.
