Priority traffic signs indicate the order in which vehicles shall pass intersection points. Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes. The general principle that establishes who has the right to go first is called "right of way" or "priority". It establishes who has the right to use the conflicting part of the road and who has to wait until the other does so. The vehicle that does not need to wait is said to "have the right of way" or to "have priority."
Types of signEdit
A Give way sign, also known as a yield sign in some countries, informs the driver that they must give way to vehicles on the major road. Under the Vienna Convention, the standard sign shall be a white or yellow inverted triangle with a red border.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> This originates in Denmark, with the red and white coming from the Danish flag.<ref>Bekendtgørelse om Hovedfærdselsaarer, 27. marts 1937, Denmark</ref> In some countries, the words Give Way or equivalent may be included with the sign. These signs are usually accompanied by a give way marking, normally one or multiple dashed lines or shark teeth across the carriageway.

Alternative priority systemsEdit
- Zusatzzeichen 1002-21 - Verlauf der Vorfahrtsstraße an Kreuzungen (von oben nach rechts), StVO 1992.svg
Sign indicating the route of priority road (thick line) at an intersection and defining the priority
- Zeichen 301 - Vorfahrt, StVO 1970.svg
Dangerous intersection with priority indication (for the next intersection only). Different variants of the sign can be used on both priority- and non-priority roads. Each sign has the thicker line indicating the road or direction that has priority with the viewer's own direction being from the bottom of the sign.
