Introduction
This page covers the general details used for all highways rules. Depending on the rule type, certain settings may not be available. Be aware that the rule editor is very flexible and allows you to configure many different rules. You should give thought to how these rules are reported to external systems. The primary mechanism for categorising rules is by using the Rule Sub-Type setting. This ensures external systems will always understand what type of alarm is being raised regardless of how many different rule configurations are used.
