    55== Introduction ==
    6 In OpenStreetMap a '''turn restriction''' limits navigation options. It represents the restriction that one cannot navigate from a [wiki:/Help/Concepts/Object way] to another way. For instance, the turn restriction depicted below forbids to drive straight. Vehicles have to turn left at the junction where the two ways meet (the so called via-node). Turn restrictions are important for routing and navigation software which are based on OSM data.

    3030=== Creating a turn restriction ===#CreateANewTurnRestriction
    3131There are several possibilities to create a new turn restriction. First, you can lauch the Turn Restriction Editor for a new turn restriction from the Turn Restriction Toggle Dialog:
    32  1. Click on [[Image(source:/trunk/images/new.png)]] in the Turn Restriction Toggle Dialog. Alternatively, select [[Image(source:/trunk/images/new.png)]]'''New''' from the popup menu.
     32 1. Click on [[Image(source:/trunk/images/new.png,20)]] in the Turn Restriction Toggle Dialog. Alternatively, select [[Image(source:/trunk/images/new.png,20)]]'''New''' from the popup menu.
    3333
    3434Alternatively, you can launch a new editor with a keyboard shortcut:
    35  1. Press the shortcut for creating or editing a turn restriction. On most plattforms the shortcut is '''Ctrl-Shift-T'''.
    36  2. If objects in the current JOSM selection already participate in a turn restriction, the following window pops up.[[BR]]
    37     [[Image(create-turn-restriction-popup.png)]] [[BR]]
    38     Just click on  [[Image(source:/trunk/images/new.png)]] '''Create new turn restriction''' to launch the turn restriction editor for a new turn restriction. Alternatively, press the key '''n''' or hit '''Enter'''.
     35 1. Press the shortcut for creating or editing a turn restriction. On most plattforms the shortcut is '''{{{Ctrl+Shift+T}}}'''.
     36 2. If objects in the current JOSM selection already participate in a turn restriction, the following window pops up.
     37 
     38 [[Image(create-turn-restriction-popup.png)]] [[BR]]
     39 Just click on  [[Image(source:/trunk/images/new.png,20)]] '''Create new turn restriction''' to launch the turn restriction editor for a new turn restriction. Alternatively, press the key '''{{{N}}}''' or hit '''{{{Enter}}}'''.

    4041In both cases, the {{{turnrestrictions}}} plugin initializes the new turn restriction with objects from the current JOSM selection:
    41  1. The first selected way in the JOSM selection becomes the ''from''-way.
    42  2. The last selected way in the JOSM selection becomes the ''to''-way
    43  3. If the ''from''- and the ''to''-way have a node in common, this node becomes a ''via''-object.
     42 1. The first selected way in the JOSM selection becomes the '''''from'''''-way.
     43 2. The last selected way in the JOSM selection becomes the '''''to'''''-way
     44 3. If the '''''from'''''- and '''''to'''''-way have a node in common, this node becomes a ''via''-object.
    4445
    4546A fast way to create a turn restriction is therefore to
    46  1. Select the ''from''- and ''to''-way in JOSM
    47  2. Press '''Ctrl-Shift-T'''
     47 1. Select the '''''from'''''- and '''''to'''''-way in JOSM
     48 2. Press '''{{{Ctrl+Shift+T}}}'''

    5253 1. Select a turn restriction in the Turn Restriction Toggle Dialog
    53  2. Click on [[Image(source:/trunk/images/dialogs/edit.png)]]. Alternatively, select [[Image(source:/trunk/images/dialogs/edit.png)]]'''Edit''' from the popup menu.
     54 2. Click on [[Image(source:/trunk/images/dialogs/edit.png,20)]]. Alternatively, select [[Image(source:/trunk/images/dialogs/edit.png,20)]]'''Edit''' from the popup menu.

    5556Second, you can launch a new editor with a keyboard shortcut:
    56  1. Press the shortcut for creating or editing a turn restriction. On most plattforms the shortcut is '''Ctrl-Shift-T'''.
     57 1. Press the shortcut for creating or editing a turn restriction. On most plattforms the shortcut is '''{{{Ctrl+Shift+T}}}'''.
    5758 2. If objects in the current JOSM selection already participate in a turn restriction, the following window pops up.[[BR]]
