Your Van Is Not a Car: The Limit You Are Driving To May Be Wrong
Most drivers learn one set of speed limits: the ones that apply to an ordinary car. Then they hire a van for a house move, tow a caravan to the coast, or start a job driving a minibus — and keep driving to exactly the same numbers they always have.
In an average-speed zone that assumption is unusually expensive, because the system does not compare you to the motorway limit. It compares you to the limit that applies to your vehicle.
Different vehicle, different number
Across Europe, heavier and commercial vehicles are generally held to lower limits than cars, and the gap tends to be widest on motorways. A van is often restricted below the car limit, a bus lower again, and a truck lower still.
The exact figures differ from country to country, so the only safe habit is to look up the limit for your vehicle class in the country you are driving in, rather than assuming the number on the sign is meant for you.
Towing changes the answer too
Attaching a trailer, a caravan or a boat usually lowers the limit that applies to you, even when the towing vehicle is an ordinary car. Many countries also apply additional rules once the combined weight passes a threshold.
This catches out holiday drivers more than professionals. The car is familiar, the route is familiar, and nothing on the dashboard announces that the rules have changed.
Why average-speed zones punish the mistake harder
A single fixed camera captures one moment: you are either over at that instant or you are not. A section measures a sustained average over kilometres, so driving a van at the car limit for the length of the zone produces a clear, unambiguous record of being over the limit for the entire distance.
There is no moment of bad luck to blame, and no plausible way to argue it was a brief lapse. The whole section states the same thing.
Signs will not always rescue you
Some countries sign the limits for each vehicle category; many do not, and simply expect drivers to know. Rental vehicles rarely carry a reminder, and the hire desk is unlikely to volunteer one.
If you drive several different vehicles, the risk is not ignorance so much as autopilot: the number that worked yesterday in the car is the number your foot reaches for today in the van.
Make the vehicle part of the setup
The practical fix is to decide the limit before you start moving, not while a section is already running. Safe Average keeps a garage of your vehicles — car, van, pickup, bus or truck — each with its own limit, so the speed it suggests during a zone belongs to the vehicle you are actually driving.
It is a small piece of setup that removes an entire category of mistake: you stop doing mental arithmetic on the move, and the suggested speed on screen is already the right one for today's vehicle.
Frequently asked questions
Are commercial vehicle limits really different?
Yes. In most European countries vans, buses and trucks are subject to lower limits than cars, particularly on motorways, and the exact figures vary by country and vehicle weight.
Does towing a caravan change my limit?
Usually yes. Towing typically lowers the limit that applies to the combination, even if the towing vehicle is a normal car, and some countries apply extra rules above certain weights.
Why is this worse in an average-speed zone?
Because the measurement is sustained. Driving to the car limit in a van across an entire section produces an average that is over your vehicle's limit for the whole distance, not just for one instant.
