Two kinds of ontheffing
- Daily ontheffing — covers a single entry on a single day. Used when a non-compliant vehicle has a one-off delivery into the zone and there is no swap available.
- Structural ontheffing — covers a defined period for a qualifying vehicle or use case, such as specialist trade vehicles, refrigerated transport, or medical equipment. The criteria are set per gemeente and require documentation.
How Fleetkeur handles it
The exemption-portal automation in Fleet Pro submits the request through the city's own ontheffing system — never a workaround or a third-party reseller. The dispatcher sees the exemption status on the van card before the plan is confirmed, and the reference number is logged against the assignment so there is a defensible record if enforcement queries it.
When an exemption is the wrong answer
An ontheffing is not a way to keep running a vehicle that should be retired. If a Euro-4 diesel is hitting Centrum runs every week, the economics favour a swap — one €130 fine recurs, but an exemption has its own administrative cost and is not guaranteed. The break-even math is in our LEZ fine economics note. For genuine specialty cases, see LEZ exemptions for trades and specialty vehicles.
Tied to the kenteken
Every exemption is anchored to a specific kenteken. Start from a kenteken milieuzone check to confirm whether the vehicle even needs an ontheffing for its destination, then file only where it is required. City detail: Amsterdam milieuzone · Rotterdam ZE-zone.
Exemption approval rests with the gemeente. Fleetkeur prepares and submits the request; it does not guarantee the outcome. Verify criteria with the relevant municipality.
