How Plan My Drive Stays Accurate in 2026: Our Sources
Driving rules are the kind of information that costs you money when it is stale: a missed sticker or an out-of-date fine figure has a price attached. Every figure behind Plan My Drive comes from the same maintained country database that feeds the per-country driving guides and emission-zone pages, and each data point traces back to a named authority — national transport ministries, city zone registries, and the official vignette operators such as ASFINAG, the Swiss customs administration and France’s Crit’Air service. This page sets out where each figure comes from and how often it is re-checked.
Where the data comes from
Every figure in Plan My Drive is drawn from our maintained country database — the same dataset behind our per-country driving guides and emission-zone pages. Each data point traces back to an authoritative source: national transport ministries, city LEZ registries, the official vignette operators (ASFINAG in Austria, the Swiss customs administration, France’s Crit’Air service, and so on), and the EU’s cross-border enforcement framework. Where a country needs an emission sticker, we link the official shop directly in the result — never a reseller, because resellers routinely charge five to ten times the government price for the identical sticker.
How often each figure is re-checked
Not everything changes at the same speed, so we don’t check everything at the same rate:
- Fast-moving figures — vignette and toll prices, fine amounts, winter-tyre date windows, newly launched low-emission zones — come first. A weekly automated job re-checks a batch of the official source pages behind them and queues any change for a person to review.
- Medium-paced rules — emission-zone rollouts, mandatory-equipment lists, licence recognition — are re-checked on a rolling schedule, with the most-used countries first.
- Slow-moving rules — which side of the road you drive on, blood-alcohol limits, international-permit treaties — rarely move and are re-checked less often, or sooner when a change is reported.
Each country and zone page shows the date it was last checked against official sources.
The autonomous freshness system
Keeping a 67-country dataset current by hand would guarantee drift. Instead, a scheduled process re-checks each fast-moving figure against its official source on a rotating basis. The design has one rule that matters above all others: it can only ever move data toward being more verified, never less.
- When the source is unchanged, the system simply records that the figure was re-confirmed on that date. Nothing on the page changes.
- When a figure has changed and the new value is corroborated by the official source, it’s updated — and the change is logged with its source and date.
- When something looks unusual — a price that jumped, a source page that changed shape, a value that can’t be confirmed — the system does not guess and does not publish. It holds the last verified value and flags the change for a human to review.
The consequence is deliberate: if a figure is ever in doubt, you get the last confirmed-correct number rather than a fresh-but-uncertain one. For legal and cost information, stale-but-right beats fast-but-wrong every time.
Dates you can see
Each result and country page carries a “last verified” date so you can judge for yourself how fresh a figure is. That date reflects the last time the underlying data was confirmed against its source — not an automatic stamp of today’s date. If a page says it was verified three months ago, that’s the truth, not a cosmetic refresh.
Help us keep it right
No dataset covering 67 countries is ever perfect, and rules can change the day after we check them. If you spot something out of date — a price that’s moved, a new zone, a rule that’s changed — please tell us through the contact page. Real corrections from drivers on the ground are one of the most valuable inputs we have, and we act on them quickly.
Before you travel: treat Plan My Drive as your shortlist and starting point. For anything that carries a fine — an emission sticker, a vignette, a winter-tyre date — confirm the specifics for your exact city and travel dates on the official source we link. That final check is always worth the two minutes.
