Kutina, Novska and Lonjsko polje: the A3 where the floodplain begins

South of this stretch of motorway lies one of the largest floodplains left in Europe. <strong>Its horses and pigs graze freely, and the roads through it have no fences</strong> — which is a sentence with consequences for anyone who leaves the A3 here.

A motorway with a wetland underneath it

The A3 runs east here between the Kutina and Novska exits, flat and fast, and most traffic passes without noticing what lies to the south. Lonjsko polje nature park stretches between Sisak and Nova Gradiska across more than fifty thousand hectares of wetland, meadow and floodplain forest, bounded by the motorway to the north and the Bosnian border to the south.

Two exits lead into it and they lead to different places. Kutina serves the western part and the visitor centre at Repusnica; Novska serves the eastern part, Jasenovac and the wooden village of Krapje with its bird reserve. Neither is a short detour: the local roads are narrow, unlit and slow.

The western end of the same plain, around Sisak and Petrinja, is a separate subject with its own article. This one is about the section a driver reaches from the A3 — and about what changes the moment the motorway is left behind.

Every year the Sava and its tributaries flood the polje. That is not a disaster here but a cycle the villages are built for. For a driver it means seasonal water on the road and verges softer than they look.

The damage patterns of this area

Free-roaming livestock. The park's Posavina horses and Turopolje pigs graze without fencing, and they cross the local roads at their own pace. A horse is high enough that the contact lands on the bonnet and windscreen rather than the bumper, which changes the whole damage picture.

Fog over the plain. The wetland produces dense ground fog in autumn and spring, thickest at dawn. Visibility drops within a few hundred metres and rear-end damage on the local roads follows the same pattern every season.

Soft verges and flooded surfaces. After high water the edges give way under a wheel, and standing water hides potholes. The result is wheel, tyre and underbody damage with no second party involved.

Farm traffic between the villages. Tractors and trailers turn off without warning into field entrances, and mud carried onto the asphalt makes the surface unpredictable for the vehicle behind.

Queue shunts at the exits. Kutina and Novska take freight and holiday traffic in the same lanes, and the tailback at the toll gates is where the low-speed rear-end damage happens.

Where the vehicle gets inspected

Kutina, Novska and Sisak are the practical points on this corridor; anything specialist happens in Zagreb. Ask at the scene where the vehicle is being taken and note it down — inside the park distances are longer than a map suggests.

We come to the vehicle wherever it stands. The order matters: photographs at the scene before anything is moved, then the inspection. On the motorway note the kilometre marker; on a local road, the nearest village and the direction of travel.

After a collision with an animal, photograph the animal's position as well as the vehicle, and report it before the scene is cleared. That record is what later separates a wildlife collision from an ordinary single-vehicle claim.

Frequently asked questions

I hit a horse on a road inside the park. What should I do first?

Make the scene safe and report it, then photograph the final positions of both the vehicle and the animal before anything is moved. Grazing livestock here has an owner, and that changes how the case is handled. The contact height on your vehicle is part of the evidence and should be recorded close up.

Is damage from flooding on a local road treated as accident damage?

It is assessed separately. Water damage to the underbody, the interior or the electrics has its own signature, and what matters is how deep the water was and how far the vehicle was driven through it. Photographs of the flooded section, taken at the time, carry more weight than any later description.

How quickly can an inspection happen around Lonjsko polje?

Usually within two days around Kutina, Novska and Sisak. Inside the park it depends on access rather than distance, especially after high water when some approaches are closed. What decides it is whether the vehicle is standing somewhere reachable.
