Croatia is doubling fines for eight of the most serious traffic offences from 1 July 2026, following the adoption of amendments to the Road Traffic Safety Act. The maximum fine jumps from the previous EUR 1,350 to EUR 2,700, which converts to roughly 5,280 KM. The minimum speeding fine rises from 65 to 130 EUR. For BiH drivers heading to the coast in summer, this is a change that hits the wallet directly, and ignorance of the new rules is not an excuse the police will accept.
This overview was prepared by the Auto Gas Gaga workshop in Banja Luka, which regularly monitors regulations relevant to BiH drivers travelling in the region.

What Changes from 1 July 2026 in Croatia
The amendments to Croatia's Road Traffic Safety Act introduce the largest increase in fines in the past decade. The focus is on eight of the most serious offences that most frequently cause fatal traffic accidents: driving the wrong way on a motorway, drastically exceeding the speed limit in built-up areas, deliberately running a red light, driving under the influence of alcohol or drugs, using a mobile phone while driving, and refusing a breathalyser test.
The previous fine range for these offences was between EUR 675 and EUR 1,350. New fines start at EUR 2,000 and go up to EUR 2,700, which at the fixed exchange rate (1 EUR = 1.95583 KM) translates to between 3,911 KM and 5,281 KM. This is not a cosmetic adjustment. It is a doubling of the amounts for offences the legislator has identified as the most dangerous.
The context matters. Croatia is a tourist country that welcomes millions of foreign drivers every summer, including large numbers from BiH. The new fines apply equally to domestic and foreign nationals. For a BiH driver who exceeds the speed limit by more than 50 km/h in a built-up area on the way to Split or Makarska, the fine can reach an amount that exceeds the average monthly salary in BiH.
Eight Most Serious Offences and New Fine Amounts
Here is a concrete overview of the eight offences that carry the highest fines from 1 July 2026 under the adopted amendments:
| Offence | Previous fine (EUR) | New fine (EUR) | New fine (~KM) |
|---|---|---|---|
| Driving the wrong way on a motorway | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Speeding 50+ km/h in a built-up area | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Deliberately running a red light | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Driving under the influence of alcohol (above 1.5 g/kg) | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Driving under the influence of drugs | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Refusing a breathalyser test | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Using a mobile phone while driving (repeat offence) | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
| Leaving children unattended in a vehicle | 675-1,350 | 2,000-2,700 | 3,911-5,281 |
Each of these offences, in addition to the monetary fine, carries penalty points, possible suspension of driving privileges, and in the most severe cases a prison sentence of up to 60 days. For foreign nationals, including BiH drivers, the police may impound the vehicle until the fine is paid or an appropriate guarantee is deposited.
Speeding Fines, Old and New
Speeding is by far the most common offence affecting BiH drivers in Croatia. The new fines in this category bring significant changes at all levels of excess speed.
The minimum fine for any speeding offence doubles from 65 EUR to 130 EUR (~254 KM). This means that even a minor excess of 10-15 km/h above the limit now costs more than most BiH drivers are used to paying.
For more serious speeding, the amounts are as follows:
| Excess speed | Fine (EUR) | Fine (~KM) | Additional consequences |
|---|---|---|---|
| Up to 10 km/h | 130 | ~254 | Monetary fine only |
| 10-20 km/h | 130-265 | ~254-518 | Penalty points |
| 20-30 km/h | 265-530 | ~518-1,036 | Penalty points |
| 30-50 km/h | 530-1,320 | ~1,036-2,581 | Penalty points, possible suspension |
| 50+ km/h in built-up area | 1,320-2,650 | ~2,581-5,183 | Up to 6 points, suspension, up to 60 days in prison |
The speed measurement tolerance in Croatia remains unchanged: 3 km/h for speeds up to 50 km/h, 10 km/h for speeds from 50 to 100 km/h, and 10% for speeds above 100 km/h. This tolerance is subtracted from the measured speed before the degree of excess is determined.
A concrete example for a BiH driver on a motorway: limit 130 km/h, measured speed 165 km/h. The tolerance is 10% of 165 km/h, i.e. 16.5 km/h. Corrected speed: 148.5 km/h. Excess: 18.5 km/h. The fine falls in the 130-265 EUR range (~254-518 KM). However, if the measured speed is 195 km/h on the same stretch, the corrected speed is 175.5 km/h, the excess is 45.5 km/h, and the fine jumps to the 530-1,320 EUR range (~1,036-2,581 KM), plus penalty points and possible temporary driving suspension. A broader overview of speeding fines by country, including BiH and neighbouring states, is available in our guide to speeding fines in BiH and abroad.
Speed Limits in Croatia That BiH Drivers Often Forget
Before travelling, it is worth reviewing the basic speed limits in Croatia:
- Built-up areas: 50 km/h (unless otherwise signed)
- Main roads: 90 km/h
- Expressways: 110 km/h
- Motorways: 130 km/h
A particularly common mistake is speeding in coastal towns, where the 50 km/h limit frequently alternates with stretches at 70 or 80 km/h. Drivers accustomed to the straight main roads in BiH tend to let the car accelerate on precisely the stretches where speed cameras are waiting.
Mobile Phone, Seatbelt and Alcohol: the Cost of Carelessness
Three offences that BiH drivers in Croatia most often underestimate now carry significantly higher fines.
Using a mobile phone while driving now costs 300 EUR (~587 KM) for a first offence. For a repeat offence, the amount rises to 2,000-2,700 EUR (~3,911-5,281 KM). In BiH, the same offence carries a fine of 100-300 KM. The difference is stark. Holding a phone in your hand while driving, even at a traffic light, is considered an offence. The only legal way to use a phone is via a hands-free system or a dashboard mount.
Not wearing a seatbelt is fined at 130 EUR (~254 KM). This applies to the driver and all passengers. For children not in an appropriate child seat, the fine is even higher and can exceed 400 EUR (~782 KM). In BiH, the seatbelt fine is 100-300 KM with one penalty point. The differences in amounts are not dramatic, but the difference in enforcement consistency is significant. Croatian police step up seatbelt checks in summer, particularly on motorways and at the entrances to towns.
Driving under the influence of alcohol is graded by levels:
- 0.5-1.0 g/kg: 265-1,320 EUR (~518-2,581 KM), penalty points, possible suspension
- 1.0-1.5 g/kg: 530-1,990 EUR (~1,036-3,891 KM), driving suspension
- Above 1.5 g/kg: 2,000-2,700 EUR (~3,911-5,281 KM), suspension, up to 60 days in prison
Refusing a breathalyser test is treated the same as the most serious level of intoxication. For professional drivers and drivers under 24 years of age, the permitted blood alcohol level is 0.0 g/kg.
The Eight-Day Payment Rule and What It Means for Foreigners
One of the most important rules BiH drivers must be aware of is the eight-day payment mechanism. Under the adopted amendments, if the offender pays the fine within 8 days of issuance, they pay only two thirds of the prescribed amount.
This rule also applies to foreign nationals, including BiH drivers. In practice, this means the following:
| Prescribed fine (EUR) | Payment within 8 days (EUR) | Saving (EUR) | Saving (~KM) |
|---|---|---|---|
| 130 | ~87 | ~43 | ~84 |
| 300 | ~200 | ~100 | ~196 |
| 1,320 | ~880 | ~440 | ~860 |
| 2,700 | ~1,800 | ~900 | ~1,760 |
For a fine of EUR 2,700, payment within the deadline reduces the amount to approximately EUR 1,800 (~3,519 KM), a saving of nearly EUR 900 (~1,760 KM). That is a significant incentive for prompt payment.
Payment methods available to BiH drivers: cash in euros on the spot, bank card on the spot (if the officer has a POS terminal, which is increasingly common on main roads in summer), or transfer to the account stated on the penalty notice within eight days. The third option requires access to a bank account that can execute an international transfer in euros, which can be a complication for some BiH drivers. The practical advice is to always bring a bank card you can pay with on the spot, because very few people carry EUR 2,700 in cash on holiday.
The problem for BiH drivers arises when the fine is not paid on the spot or within the deadline. Croatian police may confiscate a travel document or impound the vehicle until the fine is resolved. For unpaid fines from Croatia, cross-border collection is possible through bilateral agreements, although the effectiveness of this mechanism is currently limited. Nevertheless, an unpaid fine can cause problems on the next entry into Croatia.
Repeat Offenders and Licence Suspension
The new amendments particularly affect repeat offenders. The penalty points system in Croatia works cumulatively and is now stricter towards those who repeat serious offences.
For a driver who repeats a serious offence within three years of the previous one, the suspension of the driving licence for a minimum of six months is prescribed. For a third and each subsequent serious offence within the same period, the minimum suspension period is one year.
This also applies to foreign nationals. If a BiH driver commits a serious offence in Croatia and has a previous serious offence recorded in the Croatian system within the past three years, they face the risk of having their driving privileges on Croatian territory revoked. In practice, this means they may be prevented from driving on Croatian territory, even if their BiH licence is formally valid.
Additionally, for offences that carry a prison sentence (driving the wrong way on a motorway, drastically exceeding the speed limit, serious intoxication), the police may detain the driver pending appearance before a misdemeanour judge. For a BiH national on holiday, this is a scenario that can completely disrupt the trip and cause serious practical complications.
How This Affects BiH Drivers on Holiday
BiH drivers travelling to Croatia in summer must be aware that they are fully subject to Croatian traffic legislation from the moment they cross the border. No special status or treatment exists for foreign drivers, apart from the option to pay in euros or by card on the spot.
When stopped by Croatian police, the procedure is straightforward but concrete. The officer asks for a driving licence, vehicle registration certificate and green card. They check the roadworthiness of the vehicle, seatbelts of all passengers, and may administer a breathalyser test. If an offence is established, a penalty notice is issued on the spot. For BiH drivers who do not speak Croatian, communication is usually not a problem since the languages are close enough, but it is worth knowing that you have the right to request an interpreter if needed.
Here are specific tips for preparation before the trip:
Documentation. Check that you have a valid driving licence, vehicle registration certificate and green card (international insurance). A detailed document checklist and mandatory equipment list is available in our guide to driving from BiH to Croatia.
Mandatory vehicle equipment. Reflective vest, warning triangle, set of spare bulbs and first aid kit. The absence of any item is a fineable offence.
Vehicle roadworthiness. Before the trip, check brakes, tyres (minimum tread depth 1.6 mm, though at least 3 mm is recommended for motorway driving), lights, wipers and air conditioning. A defective vehicle at a roadside inspection in Croatia means not only a fine but also impounding of the vehicle until the fault is repaired. Book a pre-trip vehicle inspection to avoid unpleasant surprises on the road.
Speed and discipline. Stick to the limits, especially in coastal towns. Speed cameras are densely placed on the Adriatic main road and the A1 motorway. Use cruise control if your car has it.
Alcohol. The 0.5 g/kg limit is clear. A single beer at lunch before driving can put you right on the edge of the legal limit. In the heat, alcohol is metabolised more slowly. The safe option is simple: behind the wheel, zero.
A special warning for BiH drivers returning at night after going out in coastal towns. Croatian police intensively check for alcohol on stretches around Split, Zadar and Dubrovnik during the summer season, particularly between midnight and the early morning hours.
Stricter Vehicle Inspections and DPF Checks
Alongside the increase in fines, Croatia is stepping up checks on vehicle roadworthiness from 2026, with a particular focus on emission reduction systems.
Stricter vehicle inspections place greater scrutiny on the condition of DPF filters and catalytic converters. Unauthorised removal or modification of these systems results in an automatic failure at the vehicle inspection, and during a roadside check it can lead to an additional fine and a prohibition on further use of the vehicle.
This is particularly relevant for BiH drivers of older-generation diesel cars. In BiH, DPF inspection at the MOT is not at the same level, so it happens that drivers remove the DPF filter to reduce maintenance costs. In Croatia, such a vehicle passes neither the inspection nor a roadside check.
If you are planning a trip to Croatia in a diesel car, make sure the DPF filter and catalytic converter are intact and in place. Auto Gas Gaga performs diagnostics and exhaust system checks before trips, which is far cheaper than a fine on the other side of the border.
It is also worth mentioning that from 7 July 2026, new safety standards (GSR2) apply to all newly registered vehicles in the EU, including mandatory intelligent speed assistance, automatic emergency braking and driver fatigue detection. These standards do not directly affect BiH drivers with existing vehicles, but they will influence the used car market from the EU in the coming years. A detailed explanation of the new EU GSR2 safety standards is available in a separate article.
Comparison of BiH and Croatian Fines for the Most Common Offences
For context, it is useful to compare how much the same offence costs in BiH versus the new Croatian amounts:
| Offence | BiH fine (KM) | New Croatian fine (~KM) | Difference |
|---|---|---|---|
| Speeding (basic) | 50-200 | ~254 | 1.3-5x higher |
| Speeding 30+ km/h | 400-1,000 | ~1,036-2,581 | 2.5x higher |
| Mobile phone while driving | 100-300 | ~587 | 2-6x higher |
| Seatbelt | 100-300 | ~254 | Similar |
| Alcohol (serious level) | 1,000-3,000 | ~3,911-5,281 | 1.8-4x higher |
The differences are clear. For most offences, Croatian fines are two to five times higher than BiH fines. This is information worth keeping in mind before travelling, because otherwise a single careless moment on the Adriatic main road can cost more than the entire holiday.
How fines compare across the rest of the region is covered in detail in our complete guide to fines in BiH and abroad. Before travelling through Croatia, also check what Croatia has adopted in its new Foreigners Act for BiH drivers, as the regulations extend beyond traffic alone.
Frequently Asked Questions
When do the new fines in Croatia come into effect?
Under the adopted amendments to the Road Traffic Safety Act, the new fines come into effect on 1 July 2026. From that date, the new, significantly higher amounts apply to eight of the most serious traffic offences, along with the doubled minimum speeding fine (from 65 to 130 EUR).
What is the new fine for using a mobile phone while driving in Croatia?
The fine for using a mobile phone while driving from July 2026 is 300 EUR (~587 KM) for a first offence. For a repeat offence, the amount can reach 2,000-2,700 EUR (~3,911-5,281 KM). Holding a phone in your hand, even when stopped at a traffic light, is considered an offence.
Can BiH drivers pay the fine within 8 days for a discount?
Yes. The eight-day payment rule, which reduces the fine to two thirds of the prescribed amount, also applies to foreign nationals, including BiH drivers. For a fine of EUR 2,700, payment within the deadline reduces the amount to approximately EUR 1,800 (~3,519 KM).
What happens if a BiH driver does not pay a fine in Croatia?
Croatian police may confiscate a travel document or impound the vehicle until the fine is paid or a guarantee is deposited. An unpaid fine can cause problems on the next entry into Croatia. Cross-border collection is possible, although its effectiveness is currently limited.
Can a removed DPF filter be a problem when travelling through Croatia?
Yes. Stricter vehicle inspections in Croatia from 2026 place increased scrutiny on DPF filters and catalytic converters. Unauthorised removal or modification of these systems results in an automatic failure at the vehicle inspection and can lead to a fine during a roadside check, along with a prohibition on further use of the vehicle.
How much alcohol can a BiH driver have behind the wheel in Croatia?
The same limit as for Croatian nationals: 0.5 g/kg blood alcohol content. For drivers under 24 and professional drivers, the limit is 0.0 g/kg. Exceeding 1.5 g/kg or refusing a breathalyser test falls into the category of the most serious offences with a fine of 2,000-2,700 EUR (~3,911-5,281 KM).
