Transparency & Data Methodology

How Autovig verifies vignette prices, rules and operator data. Our commitment to accuracy and human-led verification.

At Autovig, we believe that accurate information is the foundation of a safe journey. In an ecosystem often filled with outdated prices and confusing rules, we maintain a strict verification protocol to ensure our data remains the most reliable source for European vignettes.

1. Data Collection & Sources

We do not rely on third-party scrapers or unverified aggregators. Our data comes directly from:

Primary Sources: Official national road authorities (e.g., ASFINAG for Austria, CNAIR for Romania, NÚSZ for Hungary).

Official Gazettes: Legislative updates regarding toll changes and vehicle classifications.

Direct Testing: We periodically test the checkout flows of official portals to measure real-world activation times and hidden fees.

2. The Verification Cycle

Every country page on Autovig exposes updatedAt and reviewedAt dates in frontmatter-driven metadata. Our commitment:

Price Checks: Performed weekly for Tier 1 countries and monthly for others.

Rule Changes: Monitored daily via official news feeds and legislative alerts.

Human Review: Every piece of "Information Gain" (tips, traps, exceptions) is reviewed by a human editor with travel expertise.

3. Handling Discrepancies

If a discrepancy is found between Autovig and an official source:

1 Official Priority: The official operator’s current portal price always takes precedence.

2 Immediate Correction: Once a change is confirmed, our data files are updated, and a new build is deployed to all domains within 4 hours.

3 Reporting: Users can report errors via our support channels, which triggers an immediate manual audit.

4. E-E-A-T & Authorship

Our content is written and reviewed by experts in European road travel. We don’t just "translate" rules; we interpret them to provide practical value, such as identifying the "18-day rule" traps or "Electric Vehicle" exemptions that official sites often bury in legal text.
