Defined by the consequences of a fall off the trail
The most exposed section of a route determines the exposure rating of the whole route.

Normal injury risk
- Trail is not exposed in a way that a fall would have more severe consequences as it anyway has.
- There are also no sections that are exposed but secured by safety nets to mitigate the consequences of a fall, so you will not feel vertigo.

High risk of serious injury
- A fall in such terrain carries a high risk of serious injury
- Examples: steep forest or meadow terrain below the trail, where one can stop a fall; or a 2 m high vertical drop directly next to the trail.
- There can be sections that are more exposed but secured by safety nets, so you may feel vertigo.

Life threatening consequences
- A fall in such terrain is life threatening
- Examples: steep terrain below the trail passing into a vertical drop further down, but you have a chance to stop yourself falling; or a 4 m high vertical drop directly next to the trail.
