Planning international heavy and oversized transports: why the beginning decides what happens at the end
A few years ago I had an order for a machine component to Romania. Everything seemed settled – dimensions, weight, deadline. Two days before departure the call came: a bridge on the planned route could not be used. New route, new permit, new schedule and a customer who was, quite rightly, getting nervous. Since then I have known that with a heavy transport the real work does not begin on the road, but at the desk, long before the truck is even loaded.
What actually makes such a transport special?
In Germany, a load broadly counts as a heavy or oversized transport when length, width or height exceed the usual road traffic limits, generally from around 2.55 metres in width or 4 metres in height. As soon as that is the case, the permit requirement under the Road Traffic Regulations applies. That sounds like a bureaucratic footnote. It is not. This is exactly the point at which it is decided whether a transport runs smoothly or becomes a nuisance for everyone involved.

With us, every enquiry starts with the sober facts: how long, how wide, how high, how heavy are the goods really? I have seen customers give imprecise figures here under time pressure, because an exact measurement is still outstanding. That comes back to haunt you later. An incorrectly stated height can mean that the route applied for suddenly no longer fits, because an underpass is in the way that would have been irrelevant on paper. That is why I would rather insist on one more day of lead time than on imprecise figures.
Once the goods have been measured, the route work begins.
Here we work closely with the competent authorities. In Germany this now runs largely through the nationwide VEMAGS procedure, with which the permit and licensing authorities of the federal states review applications. This is not only about road widths, but also about bridge load capacities, curve radii and underpasses. A route that looks shorter on the map can turn out to be a dead end as soon as a bridge cannot carry the weight. With international transports there is the added complication that every country has its own authorities, forms and processing times. Anyone who underestimates that loses valuable weeks.

Alongside the route, we clarify early on which escort vehicles are required.
Depending on the dimensions, a single escort vehicle is sufficient; for larger transports there are two, and in rare cases even a police escort. This requirement is ultimately set by the authority granting the permit, not by us and not by the customer. Anyone who believes they can still choose at the last moment will be disappointed. Permits often contain fixed conditions on time windows; some routes may only be used at night or at the weekend, when traffic is quieter.

One point that in my view is far too often underestimated is the loading itself.
It is not enough for the goods to fit on the low loader. They must be positioned and secured properly, with the right cargo securing equipment for exactly this weight and this shape. I have seen cases in which an otherwise clean plan failed at loading because the securing was calculated too tightly. That is why we always have someone on site who checks exactly that before departure.

But the work is not finished there.
During the journey we have regular checks carried out to establish whether the cargo securing is still tight or needs to be retensioned, particularly after longer stretches or on changing surfaces. And we plan the unloading in advance too, with the consignee, the local crane company and all other parties involved. A heavy transport that arrives on time but finds nobody ready to unload it is ultimately just as expensive as a late delivery.

What I have learned over all these years: most problems with heavy transports arise not during the journey, but beforehand – through time windows calculated too tightly, imprecise information or routes that were never properly checked. Depending on complexity, a permit takes several weeks, and considerably longer for demanding oversized transports. Anyone who ignores that and plans at short notice pays for it in the end – whether through rush surcharges, missed time windows or a route that has to be re-applied for.
I will say it quite openly: a heavy transport is not a standard order you handle on the side. It requires experience, patience and a willingness to ask uncomfortable questions before the customer does. In my view, that is exactly what distinguishes a partner who carries out such an order reliably from one who merely offers the lowest price.
Are you currently planning a heavy or oversized transport, perhaps even across several national borders? Then talk to us before the first figures are fixed. It is precisely in this early phase that it is decided whether everything runs smoothly in the end – or whether, two days before departure, you get a call like the one I described at the beginning.
FAQ on planning international heavy and oversized transports
In Germany a transport counts as a heavy or oversized transport as soon as the vehicle and load together exceed the statutory limits for road traffic – generally from around 2.55 metres in width, 4 metres in height, 20.75 metres in length or 40 tonnes gross weight. From that point on, the permit requirement under the Road Traffic Regulations applies.
There is no blanket deadline. Depending on the route, the number of authorities involved and the complexity of the transport, a permit takes from a few days to several weeks. For demanding oversized transports across several countries it can take considerably longer, because every country has its own authorities, forms and processing times.
The costs depend on the dimensions, the weight, the length of the route, the number of escort vehicles and the permit fees of the countries involved. Route surveys, night-time time windows and police escorts increase the price further. A reliable figure is only possible once the exact dimensions and the route are known.
Not always, but frequently. Whether a BF2 or BF3 escort vehicle or even a police escort is required is determined by the authority granting the permit, based on the dimensions and the route.
The permit is applied for from the competent licensing and permit authority of the relevant federal state. In Germany this now runs largely through the nationwide VEMAGS procedure. As a rule, the transport operator submits the application, not the client.
Many permits prescribe fixed time windows, frequently at night or during off-peak periods. In addition, general driving bans on Sundays and public holidays apply, from which special transports are not automatically exempt.
Yes. A heavy transport without a valid permit is illegal and is punished with a fine. In the event of damage to roads or structures, liability can also arise, and insurance cover may be at risk.
An oversized transport exceeds the permitted dimensions but stays within the permitted weight limits. A heavy transport exceeds the permitted total weight or axle loads. In practice, both frequently occur together, and the transport is then subject to both sets of requirements.
