"The e-TOLL app has stopped working" - the most common reasons for ITD fines and how to avoid them

"The e-TOLL app has stopped working" - the most common reasons for ITD fines and how to avoid them

09.04.2026

Picture this: you are setting off on a long run, several hundred kilometres ahead of you. You climb into the cab, start the engine, launch the government app on your smartphone, and after checking your balance is in credit, you pull away. The phone goes in the cradle; in the background you turn on the sat-nav and your favourite music. You drive, focused on the road, not giving payments a second thought. It is only at a rest stop, after covering nearly a hundred kilometres, that you unlock the screen and feel your stomach drop. The display shows a notification that data transmission has stopped. The e-TOLL PL app stopped working the moment you minimised it.

This is not an isolated case. That scenario plays out every day on Polish roads and is one of the most common causes of enormous stress for drivers and transport business owners. Relying on free software installed on a personal phone is a bit like driving on bald tyres – it might be fine for a while, but sooner or later it will end in disaster. And in this case the disaster is an encounter with the Road Transport Inspectorate (ITD) and a hefty fine. Let us look closely at why phone-based software can be so unreliable and how you can eliminate this problem from your life for good.

The free-solution trap: how a smartphone lets you down on the motorway

The introduction of e-TOLL and the removal of the old toll booths was a huge step forward for traffic flow, but it simultaneously shifted the technological responsibility directly onto the driver. The government app seemed like a great idea at first – after all, everyone has a smartphone with them. It quickly became apparent, however, that mobile phones were not designed to serve as professional telemetry devices.

Your phone is a multi-tasking workhorse. It is for making calls, browsing the internet, taking photos, and navigating. Operating systems such as Android and iOS are programmed to protect battery life and smooth device performance at all costs. So when you launch the road toll software and then open Google Maps and take a call from your boss, the phone’s OS starts managing memory. In a fraction of a second it decides that the background process is consuming too much power and simply kills it. An e-TOLL data transmission error occurs, and you have no idea until you glance at the screen.

Another factor is the physical conditions inside the cab. In summer, the dashboard can heat up to extreme temperatures. A phone in a windscreen mount, exposed to bright sunshine, with the screen on, GPS active, and mobile data running, overheats very quickly. The device’s protective mechanisms reduce its performance, disable connectivity modules, and can ultimately lead to an emergency shutdown. You lose the connection, and the toll collection system loses sight of you.

ITD e-TOLL inspections and fines that hit hard

The absence of an active data transmission on a paid section is the most direct route to financial trouble. The control system overseen by the National Revenue Administration and the Road Transport Inspectorate is merciless and automated. Hundreds of cameras hang over Polish roads, continuously scanning the number plates of passing vehicles. The system instantly cross-references the plate read against its database, checking whether geolocation coordinates are being received from the vehicle.

If a camera reads your plate and the system registers no signal from the app, a procedure is triggered. Many people think fines can be avoided by explaining at length about a frozen phone or poor mobile coverage. Unfortunately, the law on this point is very rigid. The obligation to ensure the constant and correct operation of the device rests one hundred per cent with the vehicle user.

What sums are we talking about? For passenger cars and light commercial vehicles with a gross vehicle weight of up to 3.5 tonnes, including those towing a trailer that takes them over that limit, the fine is 500 zł. Things become considerably more serious for lorry and bus drivers. There, failure to pay the toll costs 1,500 zł per day of the violation. What is more, notification of the penalty often arrives by post weeks later. In the meantime the driver may have covered the same section a dozen times, generating a fresh violation each time. Instead of a few hundred zlotys, a demand for thousands of zlotys lands on the desk. This is a risk that simply is not worth taking, particularly in professional transport.

What you must do before every run if you insist on using your phone

Of course, you can try to minimise the risk of using a smartphone. It does, however, require enormous discipline and treating the phone with the same seriousness as a tachograph disc. Before you even turn the key in the ignition, you need to go through an entire pre-flight checklist.

Remember to manually disable all battery-saving and optimisation options for that one specific app. You must make sure the phone has a guaranteed constant power supply from the car charger, and that the cable is not frayed anywhere. Before joining a paid section, you should check your phone’s internet signal and whether your virtual account holds sufficient funds. Once you set off, your job is to continuously – almost obsessively – glance at the screen to check whether the signal icon is still showing green. And what do you do when you enter a dead zone with no GSM coverage? Under the regulations, you should leave the paid road and wait for the signal to return. All of this makes driving stressful and diverts your attention from the most important thing: road safety.

A reliable alternative to the e-TOLL app: professional GPS trackers from Data System

Rather than spending time configuring a phone and worrying about the spectre of an inspection, a far smarter approach is to opt for tried and tested External Location Systems (ZSL) or On-Board Units (OBU). At Data System we fully understand the pain points of today’s hauliers and drivers. That is why we have developed devices that solve the road toll payment problem once and for all.

The philosophy behind our solutions is based on maximum simplicity and transparent terms. You do not sign any complex contract with us; the hardware is yours to keep, and – most importantly – we do not charge you any fixed monthly fees. You simply choose the length of time for which you want your e-TOLL GPS tracker to be active (one, two, or three years), select a warranty period, and that is it. We do not require a stack of documents or lengthy verification processes. Coming up to the end of your paid period? No problem – simply extend it for another term of your choice without any need to replace the hardware.

Every one of our trackers arrives fully ready to work straight after installation. Inside is an active SIM card, and all the software is pre-configured to transmit data seamlessly to the Ministry of Finance servers. The only thing required of you is to assign the device to your vehicle. You do this using BiznesID – a unique code found inside the packaging with every tracker. Let us look closely at our three flagship models, which will protect you effectively from fines.

DS/ZAP – maximum mobility and cigarette lighter socket power

The DS/ZAP model is the epitome of convenience – a solution created for those who value flexibility and frequently move between different vehicles. It is a compact device that requires nothing more than pushing it into the cigarette lighter socket to start working. No tools, no workshop visit, no technical knowledge needed.

The hardware works without any issues in any type of vehicle equipped with a standard 12V or 24V electrical system. It handles passenger cars, vans, lorries, and even buses without difficulty, thanks to its wide input voltage range. Because the device draws power from the cigarette lighter socket, the driver need only occasionally check that this connection is secure – particularly on very rough roads. The box contains absolutely everything needed to get started: the tracker itself, the BiznesID number, and a link to a simple, step-by-step registration guide on the government platform. Take it out of the box, plug it in, register, and forget about the problem.

DS/1STEL/LTE – discreet in-cab installation and reliable network

If you are looking for a permanent, fully discreet solution, the DS/1STEL/LTE model is the ideal choice. This hardware is designed for installation inside the vehicle cab and also supports 12V and 24V systems. It has been engineered to communicate flawlessly with satellites and mobile network masts without drawing attention to itself.

What sets this model apart from the competition most of all is its support for the modern, extremely fast LTE network. As mobile operators gradually wind down ageing 2G and 3G technologies, investing in LTE hardware is a guarantee of peace of mind for many years to come. Even in dense woodland or on motorway sections far from cities, the connection is stable and ensures lightning-fast data packet transmission. The device is ready to work immediately after installation and starts sending its signal to the right destination straight away. Supplied in the box: the tracker, BiznesID, scotchlok quick-splice connectors, heavy-duty cable ties, and a link to installation instructions.

DS/AKU LTE – non-invasive installation directly onto the battery

For the most demanding users, we have prepared a solution built for special assignments: the DS/AKU LTE model. This outstanding device relocates the telemetry module outside the vehicle cab, eliminating any risk of interference by the driver or passengers. The device attaches directly to the battery casing and draws its power straight from the terminals.

This is a superb self-installation option that removes the need to dismantle the dashboard or interfere with the vehicle’s main electrical system. All you need to do is connect two wires to the battery, wipe its surface with the cleaning cloth included in the kit, and firmly attach the tracker using the strong double-sided tape provided. Our engineers have equipped this model with an extremely sensitive satellite receiver. This means the DS/AKU LTE has an excellent view of the sky and acquires a GPS signal even when completely shielded by a heavy metal bonnet or the substantial cover protecting the batteries in heavy lorries. Like the in-cab model, this version also operates on the modern LTE network, ensuring uncompromising transmission quality. Inside the package you will find a complete installation kit, including a spanner to help loosen the battery terminals.

Why your own GPS tracker is the best investment

The decision to leave an unreliable smartphone behind in favour of the hardware described here brings considerably more benefits than simply protection from ITD fines. It is a complete shift in approach to fleet management, whether you run a sole-trader operation with one van or manage a fleet of a dozen or more lorries.

At Data System we give you something that radically increases the value of the entire package: vehicle GPS monitoring free of charge. That is right – included in the price of the device you gain a powerful analytical tool. As soon as our tracker is connected, you can track your vehicle anywhere in the country. If you travel or work outside Poland, for a very modest annual fee (99 zł for the whole European Union, or 299 zł for countries outside the EU, for LTE models) you can extend functionality to other territories.

We provide you with a free, intuitive and fast smartphone app called DSLocate, which also works via any web browser. With it you can check not only the vehicle’s current position but also easily review historical routes from previous weeks. A particularly important feature of the DSLocate system is the ability to freely block the transmission of data to the government system at any time. This is essential for business owners who use company vehicles for private purposes as well, or who travel on toll-free roads and do not want to generate unnecessary network traffic in the treasury system.

Our customer adviser Maciej talks about a professional approach to road toll payments:

‘We very often see a pattern where customers contact us for the first time only after the postman has delivered a demand for payment of a huge fine. That is when the frantic search for a quick solution begins. I always explain to business owners and drivers that purchasing a decent OBU or ZSL device is not another unnecessary business expense. You should look at it as a one-off, low-cost insurance policy. The cost of buying our tracker for several years is usually considerably less than even the lowest single fine for an unpaid toll, not to mention the enormous peace of mind the driver gains during many hours on the road.’

Summary

Travelling on toll roads in Poland need not feel like a game of Russian roulette. Although technology is evolving and government solutions rely on our smartphones, experience clearly shows that this most popular gadget is often the weakest link in the chain. How to avoid an e-TOLL fine? Stop relying on half-measures. Switching to dedicated GPS trackers – such as the reliable DS/ZAP, the innovative DS/1STEL/LTE, or the clever DS/AKU LTE – guarantees peace of mind, no nasty surprises from ITD, and free fleet monitoring all in one package. Installation is straightforward, there are simply no hidden costs, and you gain the freedom and assurance that every time you pass under a gantry it is correctly recorded. Do not wait for your first fine – optimise your transport operation today.


Frequently asked questions (FAQ)

Do I need an auto-electrician to install Data System trackers? Not at all. Both the DS/ZAP and the non-invasive DS/AKU LTE have been designed specifically for quick, self-installation. Installation involves simply inserting the plug into the cigarette lighter socket or tightening two wires to the battery. The in-cab models, although they require connection to a permanent power supply, are also straightforward thanks to the connectors supplied.

What should I do if I notice any technical problem with route recording while driving? Under the strict regulations, if you lose the ability to transmit GPS coordinates, you are required to leave the paid road at the nearest junction immediately. It is possible to declare a missing trip in the system, provided a registered geolocation device is assigned to the vehicle. Having a dedicated tracker reduces this risk to virtually zero, avoiding the pitfalls of smartphone-based systems.

I bought a Data System device for one year. What do I need to do when that time is up? Our offering has no binding subscription contracts. Before the end of your chosen period (one, two, or three years), you can easily extend the service for another term of your choice. The device stays with you; you continue to enjoy free access to the route management app, with no hidden charges for hardware replacement.

Does the free DSLocate monitoring only work in Poland? In the basic version included in the package price, monitoring lets you freely view journey history and the vehicle’s current position within Poland. We understand the needs of the transport market, however, so a small one-off annual fee is all it takes to extend the app’s coverage to the entire European Union or countries beyond its borders. LTE-based modules handle this without the slightest difficulty.
