What is the most important measurement for driving a van in Europe?

The maximum authorised mass (MAM) — your van's legal fully-loaded weight, printed on its registration, not what it weighs today. The 3.5-tonne line governs which licence you need, which toll class you pay, your motorway speed limit and which vignette category applies. It matters more than any other figure, which is why most production motorhomes are sold at exactly 3,500 kg.

Does my motorhome's height affect tolls?

Yes. Once you're over about 3.0 metres, the overhead sensors at French (and some other) motorway booths can automatically charge you a higher HGV toll class, even if your van is under 3.5 tonnes and would otherwise pay the car rate. Crucially that height includes everything on the roof — a box, solar panel, satellite dome or air-con unit can tip you over. Slovenia also charges a higher vignette class for tall vehicles.

What changes if my van is over 3.5 tonnes?

A lot. You need a C1 licence rather than a standard car licence (UK drivers who passed before 1997 are usually grandfathered), you pay HGV toll classes, your motorway speed is limited to roughly 80–100 km/h, and you fall into heavy-vehicle charging systems such as Austria's GO-Box, Germany's Maut and Switzerland's heavy-vehicle charge. A revised EU licence directive agreed in 2025 may eventually let car-licence holders drive up to 4.25 tonnes after extra training, but rollout is left to each country.

Will my van fit? The Europe dimension & class checker

Four numbers decide where your van can legally go in Europe — height, length, width and weight — and crossing one of them quietly changes your licence, your tolls, your speed limit and which roads you can use. Enter your van's figures below and this checker flags every threshold you cross and what it means, so you know before you're stuck at a booth, a bridge or a barrier.

Enter your van's numbers

Use your real figures — height including everything on the roof, and weight as the MAM from your registration, not today's load.

Height metres

Width metres, incl. mirrors

Length metres

Weight / MAM kilograms

Guidance for 2026, simplified for planning. Thresholds are general European norms — individual countries, structures and operators set their own limits and exceptions, and posted signs always override. Confirm the specifics for your route, and never treat a clearance figure as exact: measure your van yourself and add a safety buffer.

The four numbers, and the one that matters most

Every figure you need is on your registration document (the V5C, carte grise or Fahrzeugschein), usually buried in a grid of codes. Height decides which bridges and tunnels you clear and which toll sensors reclassify you; length decides parking, aire pitches and ferry bands; width is rarely binding but bites on tight lanes and ferry decks; and MAM — maximum authorised mass, your legal loaded weight — decides almost everything else. For the full background on each, see our van dimensions guide.

3.5 tonnes is the line that changes everything

Stay under it and you live one life — car licence, car toll class, car speed limits, standard vignettes. Cross it and you need a C1 licence, pay HGV toll classes, are limited to roughly 80–100 km/h on motorways, and fall into heavy-vehicle charging like Austria's GO-Box and Germany's Maut. It's why most motorhomes are sold at exactly 3,500 kg. A 2025 EU licence reform may eventually allow car-licence holders up to 4.25 tonnes after extra training, but rollout is country-by-country.

Measure for real, not from the brochure

The checker is only as good as your numbers, and the brochure figures are the ones that catch people out:

Height must include everything fixed above the roof — boxes, solar panels, satellite domes, air-con, antennas, bars. Measure on level ground, then add about 20 cm of buffer when reading any posted clearance.
Width that matters at tight gaps is width including mirrors, which can add 20–30 cm over the body figure. Fold them in for gantries and ferry slots.
Weight is the MAM — the legal maximum loaded weight printed on the registration — not what your van weighs today. A lightly-loaded van with a 3,500 kg MAM is still a 3,500 kg vehicle for every rule.
Length governs where you'll fit: the 6.5–7.5 m band is the production sweet spot for parking and aire pitches, and ferries price by length band, so a longer van costs more to ship.

Let the planner do the checking on every road

Give WiseTrip your van's real height, length, width and weight once, and it routes around bridges you can't clear, flags toll-class jumps, and warns where vignettes change category — for the whole trip, not just one booth. Free, no account.

A note on accuracy

This tool gives you the shape of your van's status against common European thresholds — it isn't a legal classification. Limits, licence rules and toll bands vary by country and change over time (the EU's 4.25-tonne reform being a live example), and a posted clearance or weight sign always wins. Use it to know what to watch for, read the linked guides for the detail, and verify anything that's close to a line.
