Intervention matrix

The Human Environment and Transport Inspectorate (ILT) uses the National Enforcement Strategy (LHS)'s intervention matrix to determine the most appropriate intervention with the largest possible social impact.

The National Enforcement Strategy (LHS) is the foundation for ILT's enforcement strategy. It is a tool to determine the most fitting intervention for any violation and guarantees that offenders are treated equally.

ILT has made detailed descriptions for all its enforcement areas. The Inspectorate has used the LHS' intervention matrix to determine suitable interventions for the most common or most serious offences within each enforcement area. These are based on the seriousness of the (possible) consequences of a violation for transport, infrastructure, environment or housing, and on the violator's behaviour.

The Inspectorate takes aggravating or mitigating circumstances into account when determining an intervention. Repeated violations of laws and regulations are usually considered aggravating circumstances.

There may be aggravating aspects to take into account as well. For example, the aim to benefit financially from a violation. The more aggravating aspects, the more reason to add criminal proceedings to administrative ones.

Intervention strategy principles

  • When choosing an intervention, its effect is leading.
  • An effective intervention is appropriate, effective and deterrent.
  • ILT focuses on risk and information; inspectors assess both social damage and the violator's behaviour to determine the most suitable intervention.
  • There are no strict guidelines for the order of interventions.
  • ILT will only deviate from its Enforcement Strategy in extraordinary circumstances.
  • The Inspectorate measures the social effects of an intervention to continually evaluate its Enforcement Strategy.

Transitional law

ILT's current enforcement strategy came into effect on 14 May 2021. It therefore applies to all violations on or after this date. Parties under supervision are not negatively affected by this change in the intervention framework.
