The TPU (Post-Use Fee) is a municipal administrative fee charged when Zona Azul time runs out and the vehicle stays in the bay — it works like a "second chance" to set things right before the fine. Important: the TPU is not a traffic fine, it does not add points to the license, and it exists only where the city has decided to adopt it. Where it exists, paying the TPU within the deadline avoids the citation.
What the TPU is for
When the activated credit expires and the car remains parked, the municipal system does not apply the fine immediately (in the cities that use this model). Instead, it generates a Post-Use Notification (NPU) warning that the time is up and, next, the TPU, which is the amount to pay to bring the situation up to date. It is a mechanism designed for the driver who forgot to renew: they pay a modest fee and avoid a fine. Only when the TPU is not paid within the deadline does the case become a violation report.
TPU is a municipal fee, the fine is federal
This is the distinction that most confuses people, and it is worth fixing in mind:
- The TPU is a fee defined by municipal law or decree. The city decides whether it exists, how much it costs, and what the deadline to set things right is.
- The fine under CTB Art. 181, XVII is a federal penalty, with a fixed amount throughout the country: a serious violation, R$ 195.23, 5 license points, and vehicle removal. The city writes the report, but does not change this amount.
In other words: what varies from city to city is the fee/TPU — never the fine.
The TPU varies in three dimensions
Because it is municipal, the TPU is a true "tower of Babel" of rules. It can change in three independent aspects, always defined by the city's law:
| Dimension | What varies | Illustrative examples |
|---|---|---|
| Exists or not | Some cities adopt a TPU; others go straight to the fine | Cities A and B have one; another may not |
| Amount | Usually a few dozen reais; may be tiered | City A: R$ 20 / City B: R$ 40 / City C: R$ 10 at first and R$ 50 later |
| Deadline to set things right | Time to pay before it becomes a fine | City A: 4h / City B: 5 days / City C: up to 10 days |
The amounts and deadlines above are only illustrative examples (City A/B/C). Never take any figure as nationwide: always check your city's legislation.
The complete sequence: from expiry to fine
- Time runs out — the activated credit expires.
- Grace period (if any) — a small allowance, set by the city.
- NPU — notice — notification that the bay remains occupied after the deadline.
- TPU — setting things right — a fee to bring it up to date, with its own deadline.
- Fine under Art. 181, XVII — only if the TPU is not paid: serious, R$ 195.23, 5 points, removal.
How to pay the TPU without hassle
In the municipalities served by Areatec, the TPU is shown and settled through the Digipare app, along with normal credit activation. Practical tips:
- Watch the notifications in Digipare: the NPU and the TPU appear with the payment deadline.
- Pay within the municipal deadline so that the case does not escalate to the federal fine.
- Check your city's law: whether the TPU exists, how much it costs, and in how many days or hours it can be paid.
Areatec's electronic enforcement — with the largest OCR fleet in the world and automatic plate reading — records occupancy with geotagged, time-stamped photos, providing legal certainty both for the city and for the driver who needs to set things right.
