Every Crit’Air, ZBE and ZTL zone on your route, in the order you will meet it.

One road, France, Italy and Spain, and a rulebook that changes under your wheels. Tell Solstice what you drive, where you are going and when — it returns what applies to that vehicle on that road on that date, and nothing that does not.

The bridge decides what you are. The registration document does not.

A posted axle load, a headroom plate, a width at the arch. Solstice holds the limits for every structure on the route and reads them against the vehicle you actually gave it — laden, with the roof box on.

A restricted zone has no barrier. The camera does not warn you.

The boundary is invisible from the driving seat. The plate is read at the gate, and the notice arrives months later at the address on the registration. Every boundary here comes from the authority’s own published geometry — none are traced by hand.

A sticker you order the day before you leave is a sticker you do not have.

Anyone will tell you which sticker a zone wants. Nobody tells you how long it takes to arrive. We carry the lead time beside the requirement, because the lead time is what decides whether you can go at all.

Some days the answer is no, and the date is the only thing that changes it.

You cannot go on that date. Here is what you would need, how long it takes, and what changes if you leave later. No requirement on this route is unmeetable. This one is only unmeetable this soon.

Above a thousand metres the vehicle changes category twice.

Winter tyres. Chains carried. Chains fitted. Three different obligations, each with the dates it runs between and the altitude at which it starts — ordered as the road takes them, not as a table of countries.

The rulebook changes inside the tunnel, not at the sign.

Warning triangle, high-visibility vest, spare bulbs, breathalyser. The list is different on the far side, and so is the penalty for not having it. A col at noon in November is a poor place to find that out.

Three systems share one word, and only two of them stop you.

A barrier interrupts you, which is its own kind of warning. A vignette you can buy at the border. Free-flow does neither: it photographs the plate and waits.

New numbers, and one of them is zero for you.

Alcohol limits, speed limits, and the exemptions that quietly change them: a heavier vehicle, a towed load, a licence held under three years. Read against the class you entered, never the generic figure on the sign.

Where the source is silent, we say so and name who to ask.

A route never goes green through a country whose cells are incomplete. Where an authority contradicts itself, the row says which two documents disagree and gives you the office that settles it. Every row carries the date it was last read.

The last two kilometres are the ones that fine you.

A historic centre with a timed pedestrian zone, a delivery window that closed at nine, and a residents-only gate that closes again at seven. The smallest requirement on the route, and the most expensive one to miss.

10 requirement types, 6 authorities, one sheet — in the order you met them.

Every row names the authority that published it and the date it was last checked. Nothing is inferred, and nothing that does not apply to your vehicle appears at all.
