Slovakia Truck Rules from September 1, 2026: Weight Limits, Driving Bans and Fines
Truck drivers and transport companies operating through Slovakia need to prepare for important road-traffic changes taking effect on 1 September 2026.
The changes affect overloaded trucks, axle loads, weekend and holiday driving restrictions, serious speeding offences and automated enforcement.
For international carriers crossing Slovakia, even a transit journey may now require more careful planning.
What changes for trucks in Slovakia from September 1, 2026?
The new rules are introduced by Slovak Act No. 131/2026, which amends the country's Road Traffic Act and related legislation.
The most important changes for truck operators include:
a 10% overload threshold for classification as a serious traffic violation;
changed hours for Sunday and holiday truck restrictions;
violations of certain truck driving bans becoming serious traffic offences;
higher penalties for the most serious speeding offences;
wider use of technical systems to record traffic violations.
The changes apply from 1 September 2026.
Slovakia's 10% truck overload rule
One of the most important changes concerns vehicle weight.
From September 2026, exceeding the technically permissible maximum mass by at least 10% can qualify as a serious violation of Slovak road-traffic rules. The legislation also covers relevant vehicle-combination and axle weight limits.
10% does NOT mean a legal tolerance
This is particularly important.
A truck is not automatically allowed to operate up to 10% overweight.
The 10% figure determines when the infringement reaches the threshold for classification as a serious violation. Lower overloads may still breach applicable weight rules and may still result in enforcement or penalties.
For example, if a technically permissible weight were 40,000 kg, 10% would equal 4,000 kg. Reaching 44,000 kg would therefore cross that illustrative 10% threshold.
However, operators must always use the actual technical, axle and route limits applicable to the specific vehicle and journey.
Before departure, carriers should check both total vehicle weight and individual axle loads.
EuroTruckTools' Truck Payload Calculator and Axle Load Calculator can help with pre-trip planning, but an actual weighbridge result and official vehicle limits remain decisive.
Truck driving-ban hours are changing
Slovakia also changes the hours of restrictions applying to certain heavy vehicles.
The rules cover vehicles above 7.5 tonnes, as well as motor vehicles above 3.5 tonnes towing a trailer, on motorways, roads for motor vehicles and first-class roads.
Under the amendment:
Sunday and the last day of a non-working period:
Old start: 00:00
New start: 06:00
End: 22:00
The legislation specifically changes the start from midnight to 06:00.
The summer restriction is also adjusted: the start of the relevant July–August Saturday restriction moves from 07:00 to 09:00, while the end remains 19:00.
This gives operators a larger morning operating window, but it does not remove the truck ban.
Breaking the truck driving ban becomes more serious
Carriers should not interpret the shorter restriction period as relaxed enforcement.
The amendment adds violation of the truck-driving restrictions under Section 39(1) or (2) to the list of serious road-traffic violations.
Dispatchers should therefore check Slovak weekend and holiday restrictions before planning arrival, transit or delivery times.
A route that reaches Slovakia only a few hours earlier or later could produce a very different legal result.
Higher fines for serious speeding
Slovakia is also increasing penalties for the most serious speeding offences.
For the relevant highest-level speeding offence, the administrative fine increases from €500–€1,000 to €800–€1,300.
In block or order proceedings, the range increases from €250–€800 to €500–€1,000.
The highest speeding category concerns exceeding the limit by more than 50 km/h in a built-up area or more than 60 km/h outside a built-up area.
For professional drivers, the financial penalty is only part of the risk. Serious traffic offences can also have consequences for driving privileges and a driver's professional record.
More violations can be detected automatically
Another important part of the reform is enforcement.
Slovak legislation expands the framework under which vehicle-owner offences can be recorded using technical equipment operated by police and, under specified arrangements, equipment operated by road or motorway authorities and other infrastructure managers.
This means drivers should not assume that avoiding a roadside stop means a violation has gone unnoticed.
For transport companies, automatic enforcement also makes accurate vehicle, driver and route management increasingly important.
New exemptions also appear
The September amendment does not only introduce stricter rules.
It expands several exemptions from truck-driving restrictions. Among them is an exemption for vehicles returning into Slovakia to the destination of their journey, together with other specified transport categories.
However, international operators should not assume that an exemption applies automatically to their particular trip. The exact conditions should be checked before relying on one.
What should carriers do before driving through Slovakia?
Before a truck enters Slovakia after 1 September 2026:
Check the actual gross vehicle and combination weight.
Check individual axle loads.
Do not treat the 10% threshold as permitted overload.
Check whether the trip falls inside a Sunday or holiday truck restriction.
Review arrival and departure times with dispatch.
Make sure drivers understand the higher penalties for serious speeding.
Expect greater use of automated enforcement.
