The traffic register (Liiklusregister), operated by the Transport Administration (Transpordiamet), holds vehicles, owners, driving licences, tachograph cards and professional-driver training. The largest consumer is the Chamber of Bailiffs — vehicles are attachable assets. The traffic insurance fund, the police (a dedicated pol_ service family for traffic control) and even the island-ferry operator (discounts by vehicle registration) also query it.
The traffic-register services fall into four clusters — vehicle data (the core), driving licences, exams & professional drivers, and police access. Shares are daily averages over Dec 2025 – May 2026. Each cluster has its own detail page.
The most-used service endpoints across all four clusters, as requests per day. The cluster pill links to the detail page.

How do the 0.80 M calls/day flow from the service clusters to the 16 largest consumers?
Morning and afternoon peaks — the rhythm of authorities, insurers and police traffic control.
What the aggregate data reveals about Estonia's traffic register.
With about 391,000 calls per day the Chamber of Bailiffs leads the field — vehicles are attachable assets and the owner is determined live. As with the land register, enforcement is the biggest driver.
The saarteLaevPiletSoodust service grants island residents ferry discounts based on their vehicle registration. The ferry operator TS Laevad checks live.
The police do not use the general queries but a dedicated pol_ service family (pol_isikud3, pol_soidukid2, pol_juhtoigus). A separation of administrative routine and operational traffic control.
