'''TOTSO''' is a term for a special form of [[road junction]].
==Defintion==
TOTSO is an [[acronym]] which stands for ''Turn Off To Stay On''<ref>http://www.cbrd.co.uk/reference/dictionary/#totso</ref>. It is used to describe junctions where a motorist has to ''turn off'' the current physical [[road]], to ''stay on'' a particular [[road number]]. If the main through road is followed through the junction, one will join a seperate route.
==Occurance==
TOTSOs exist in principle in many cities, where a street name does not follow the through road. However, the term is used mainly for [[highways]] because the phenomenon is not the expected behaviour for major routes, and can be confusing for motorists unfamiliar with the junction.
==Examples==
===Germany===
* On the [[Bundesautobahn 4|A4]], at the Heumar triangle junction in [[Cologne]], motorists from the west must turn off to continue on the A4.
* At the junction of the [[Bundesautobahn 5|A5]] and [[Bundesautobahn 67|A67]] is a striking example where motorists on both roads from all directions must ''TOTSO''.
===United Kingdom===
====[[Motorways]]====
* On the [[M6 motorway]], motorists heading south must turn off to remain on the M6, as the through road becomes the [[M6 Toll]]
* On the [[M25 motorway]] at junction 5 near [[Sevenoaks]], a motorist continuing around the M25 in either direction must ''TOTSO'', as the anticlockwise carriageway continues as the [[M26 motorway|M26]] to the east and the clockwise carriageway as the [[A21 road|A21]].
* On the [[M42 motorway]] near [[Birmingham]], motorists heading from the [[M5 motorway|M5]] must TOTSO as the through road becomes the [[M40 motorway|M40]]. Further north, motorists must TOTSO again as the through road becomes the [[M6 Toll]].
====[[A_roads_in_Great_Britain#A_roads|A Roads]]====
* The [[A159 road|A159]] near [[Scunthorpe]] features two TOTSOs in quick succession.
* The [[A205 road|A205]] south circular in [[London]] is not a purpose-built route, but a collection of pre-existing suburban roads joined together. As a result there are frequent TOTSOs.
* The [[A271 road|A271]] in [[East Sussex]] features a TOTSO, where the through road changes to the [[A269 road]]
===United States===
* At the [[East Los Angeles Interchange]], a number of TOTSOs exist: Northbound on the [[I-5]], as the route changes from following the [[Santa Ana Freeway]] to the [[Golden State Freeway]]; Westbound on the [[I-10]], as the through road heads to [[U.S. Route 101]]; Westbound on [[California State Route 60|SR 60]] as the through road heads to the I-10. The Santa Ana Freeway is the only road that crosses the complex without a TOTSO.<ref>http://www.scvresources.com/highways/east_los_angeles_interchange.htm</ref>
