+
+#### `highway_turn_classification` and `access_turn_classification`
+When setting appropriate turn weights and duration, information about the highway and access tags of roads that are involved in the turn are necessary. The lua turn function `process_turn` does not have access to the original osrm tags anymore. However, `highway_turn_classification` and `access_turn_classification` can be set during setup. The classification set during setup can be later used in `process_turn`.
+
+**Example**
+
+In the following example we use `highway_turn_classification` to set the turn weight to `10` if the turn is on a highway and to `5` if the turn is on a primary.
+
+```
+function setup()
+  return {
+    highway_turn_classification = {
+      ['motorway'] = 2,
+      ['primary'] = 1
+    }
+  }
+end
+
+function process_turn(profile, turn) {
+  if turn.source_highway_turn_classification == 2 and turn.target_highway_turn_classification == 2 then
+    turn.weight = 10
+  end
+  if turn.source_highway_turn_classification == 1 and turn.target_highway_turn_classification == 1 then
+    turn.weight = 5
+  end
+}
+```
