# RestrictionLabelValue

This code list is used in association with the Restriction attribute which is present within the Turn Restriction Feature Type. It describes the type of turn restriction. E.g. 'no\_right\_turn', 'only\_straight\_on'.

| Label              | Definition                                                                                        |
| ------------------ | ------------------------------------------------------------------------------------------------- |
| no\_right\_turn    | Prohibitory restriction: a valid route may not proceed along the restriction relation's geometry. |
| no\_left\_turn     | Prohibitory restriction: a valid route may not proceed along the restriction relation's geometry. |
| no\_u\_turn        | Prohibitory restriction: a valid route may not proceed along the restriction relation's geometry. |
| no\_straight\_on   | Prohibitory restriction: a valid route may not proceed along the restriction relation's geometry. |
| only\_right\_turn  | Mandatory restriction: a valid route must proceed along the restriction relation's geometry.      |
| only\_left\_turn   | Mandatory restriction: a valid route must proceed along the restriction relation's geometry.      |
| only\_u\_turn      | Mandatory restriction: a valid route must proceed along the restriction relation's geometry.      |
| only\_straight\_on | Mandatory restriction: a valid route must proceed along the restriction relation's geometry.      |
