Zones A and B for buses: decoding, rules and fines in

Zones A and B for buses, this is a classification of vehicles by environmental class, which directly affects the ability to enter city centers, paid parking lots and limited traffic areas. Unlike passenger cars, where the division into zones is often associated with weight or dimensions, for buses the criterion is environmental standard Euro, confirmed in PTS or STS. If your bus enters the zone B, you risk receiving a fine of up to 5,000 ₽ when entering the center of Moscow, St. Petersburg or other cities with eco-restrictions - even if you have permission to transport passengers.

From January 1, 2026, the rules have become stricter: now the zone is checked not only visually by traffic police inspectors, but also automatically - through photo recording cameras linked to the traffic police database. This means that bus owners Euro 2 and below (zone B) are automatically subject to a ban on entry into low-emission zones (LEZ) without special permission. Moreover, for buses Euro 5 and Euro 6 (zone A) there are benefits - for example, free travel on toll roads in some regions.

The problem is that many bus drivers confuse the zones A/B with vehicle categories (for example, D or D1 in rights) or with cargo hazard class (for trucks). This leads to fines and traffic bans. In this article, we will look at how to accurately determine your zone where restrictions apply, and how to legally enter closed zones if your bus falls into the category B.

What do zones A and B mean for buses: official definition

Zones A and B for buses - this is the classification introduced by Order of the Ministry of Transport of Russia No. 36 from 2020 (as amended in 2023). It separates vehicles by environmental class, which is indicated in clause 13 PTS or clause 14 STS (if the class is not specified, the bus automatically belongs to the zone B). The main difference from passenger cars is that for buses not only the standard is taken into account Euro, but also engine type (petrol, diesel, gas, electricity).

According to the current rules in 2026:

• 🚌 Zone A — buses with environmental class Euro 5 and above (including Euro 6, electric buses, methane buses). These vehicles have the right to freely enter low-emission zones (LEZ) without additional permits.
• 🚍 Zone B - buses with class Euro-0–Euro 4, as well as those whose class is not indicated in the documents. They are subject to restrictions: a ban on entering the NEZ without permission, increased tariffs on toll roads, and parking restrictions.

Important: classification A/B does not depend on vehicle category (for example, D for buses with more than 8 passenger seats). This is a separate system that works in parallel with other rules. For example, a bus category D1 (up to 16 seats) can be treated as a zone A, and to the zone B — it all depends on its environmental class.

⚠️ Attention: If your PTS or STS does not have a record of environmental class, the bus automatically falls into the zone B. This rule applies even to new buses manufactured after 2016. To correct the situation, it is necessary to undergo testing in an accredited laboratory and make changes to the documents.

How to determine which zone your bus belongs to

To find out if your bus is in the zone A or B, follow 3 steps:

1. Check PTS or STS. Look for the item 13 "Ecological class" (in PTS) or 14 "Limitations" (in STS). If it is indicated there Euro 5 or Euro 6 - your zone A. If the class is not specified or lower Euro 5 - zone B.
2. Check the year of manufacture. Buses produced before 2014 are highly likely to belong to the zone B, since the standards Euro 5/6 became mandatory later. The exception is buses that have undergone engine modernization.
3. Check with the traffic police service. On the website traffic police in the "Vehicle Check" section you can enter the VIN or license plate number and find out the environmental class. If there is no data - the bus is in the zone B.

If the documents do not contain information about the environmental class, but you are sure that the bus complies Euro 5/6, you can:

• 📋 Contact technical center to pass the test and receive a certificate.
• 📄 Submit an application to the traffic police to make changes to the PTS/STS (an expert opinion will be required).
• 💻 Register on the portal Autocode and request a certificate of environmental class.

1. Find point 13 in the PTS or point 14 in the STS

2. Check the year of manufacture (before 2014 - probably zone B)

3. Check the bus through the traffic police service using VIN or license plate number

4. If there is no class, contact the technical center for examination -->

Particular attention should be paid to buses on gas fuel (methane, propane). Even if they match Euro 5, in some regions (for example, in Moscow) additional rules apply for them. For example, gas zone buses A may enter the NEZ, but must have a valid LPG equipment inspection certificate.

Where restrictions apply for zone B buses

Zone bus restrictions B apply in the following cases:

Restriction type	Cities/regions	Penalty for violation
Prohibition of entry into NEZ (low-emission zones)	Moscow, St. Petersburg, Kazan, Sochi, Krasnodar	5,000 ₽ (according to Article 12.16 of the Administrative Code)
Increased tariffs on toll roads	M-4 "Don", M-11 "Neva", Central Ring Road	From 1,500 to 3,000 ₽ for travel
Parking restrictions in the city center	Moscow (within the Third Transport Ring), St. Petersburg (historical center)	3,000 ₽ + evacuation
Prohibition on participation in government orders for passenger transportation	All regions of the Russian Federation	Exclusion from the tender

In Moscow and St. Petersburg, low-emission zones (LEZs) cover almost the entire city center. For example, in Moscow this is the territory inside Third Transport Ring (TTK), and in St. Petersburg - the historical center (inside Obvodny Canal). For zone buses B Entry into these zones is permitted only with a special permissions, which is issued:

• 🚏 For shuttle buses (under agreement with Department of Transport).
• 🏢 For buses serving government agencies (schools, hospitals).
• 🚑 For ambulance and emergency services.

⚠️ Attention: Since 2026, it has been operating in Moscow automatic photo recording violations in zones A/B. The cameras scan license plates and check the environmental class through the traffic police database. If the bus zone B enters the New Economic Zone without permission, the fine will be sent by mail within 10 days.

In some regions (for example, in Kazan and Sochi) time restrictions apply. For example, zone buses B can enter the center only at night (from 22:00 to 6:00) or on weekends. The exact rules need to be clarified on the websites of local administrations.

Zone A (Euro 5/6)|Zone B (Euro 0–4)|I don’t know, I need to check|I don’t have a bus-->

Fines for violating the rules of zones A and B in 2026

Fines for violating zone rules A/B for buses are regulated Art. 12.16 Code of Administrative Offenses of the Russian Federation (failure to comply with the requirements prescribed by road signs) and Art. 8.23 Code of Administrative Offenses of the Russian Federation (violation of air protection rules). The amount of punishment depends on the type of violation:

• 🚫 Entry into the New Economic Zone without permission: 5,000 ₽ (for individuals) or 50,000 ₽ (for legal entities).
• 💰 Failure to pay an increased tariff on a toll road: from 1,500 to 3,000 ₽ (depending on the route).
• 🅿️ Parking in a prohibited area: 3,000 ₽ + evacuation to the impound lot (storage cost - 1,000 ₽/day).
• 📄 Lack of documents for environmental class: 2,000 ₽ (if a traffic police inspector stopped for an inspection).

The peculiarity of fines for buses is that they are often issued not to the driver, but to vehicle owner (if the bus belongs to the company). This means that even if a hired driver was driving, the organization to which the bus is registered bears responsibility.

How to appeal a fine:

1. Check whether the environmental class is indicated correctly in the traffic police database (sometimes there are errors).
2. If the class in the documents and the database does not match, submit an application to the traffic police to correct the data.
3. If the fine was issued incorrectly (for example, you had an entry permit), attach a copy of the permit to your complaint.

How to legally enter the NEZ on a zone B bus

If your bus belongs to the zone B, but you need to enter a low-emission zone (for example, for passenger transport or event services), there are 4 legal ways:

1. Obtain entry permission.
   • 📄 For shuttle buses - through the Department of Transport or the city administration.
   • 🏢 For corporate buses — through the public services portal (confirmation from the employer is required).

   The permit is valid from 1 day to 1 year. Cost - from 500 to 5,000 rubles.

2. Install a diesel particulate filter (DPF) or SCR system.

   If you upgrade the bus to standard Euro 5, you can transfer it to the zone A. To do this you need:

   • 🔧 Be tested at an accredited center.
   • 📋 Receive a certificate of conformity.
   • 📄 Make changes to the PTS/STS.

   The cost of modernization is from 200,000 to 500,000 rubles.

3. Use alternative routes.

   In some cities (for example, Moscow) for bus zones B detours are provided. Maps with permitted routes are published on the websites of local administrations.

4. Re-register the bus for gas fuel.

   Buses to methane or propane often referred to as the zone A, even if the base engine is Euro 4. To do this you need:

   • 🔧 Install HBO in a certified center.
   • 📋 Pass the compliance check Euro 5.
   • 📄 Make changes to documents.

Important: if you receive permission to enter, but the bus does not meet the declared environmental class (for example, in the documents Euro 5, but in fact - Euro-3), you can be fined 50,000 rubles for forgery of documents (Article 327 of the Criminal Code of the Russian Federation).

Frequent mistakes and myths about zones A and B

Bus drivers and owners often encounter incorrect information about zones A/B. Let's look at the most common myths:

• 🚗 "Zones A and B are the same as categories D and D1 in driving license."

  Reality: Categories in rights (D, D1) determine bus size and the right to manage, and zones A/B - him environmental class. Bus category D1 (up to 16 seats) can be in a zone A, and in the zone B.

• 📅 "If the bus is new (2020), it is automatically in zone A."

  Reality: Even new buses may belong to the zone B, if their environmental class is lower Euro 5. For example, some Chinese buses (Golden Dragon, Higer) until 2021 were issued with a class Euro 4.

• 💨 "If you put a filter on the exhaust, the bus will go to zone A."

  Reality: Installing a diesel particulate filter (DPF) or SCR system is only part of the process. You need to officially confirm your class Euro 5 in an accredited center and make changes to the PTS.

• 🚏 "Mutual buses can travel through the New Economic Zone without restrictions."

  Reality: Even zone shuttle buses B must have special permission. Exception: buses Mosgortrans and municipal transport, which automatically gain access.

Another common misconception is that electric buses always belong to the zone A. In fact, if an electric bus was produced before 2016 and its PTS does not indicate an environmental class, it may formally fall into the zone B. To avoid problems, owners of such buses are recommended to obtain a certificate of zero emissions from Rosstandart.

FAQ: Answers to frequently asked questions about zones A and B for buses

My bus is 2015, the PTS does not have an environmental class. Is this zone B?

Yes, if the environmental class is not indicated in the PTS or STS, the bus automatically belongs to the zone B, even if it's new. You need to contact an accredited center to determine the class and make changes to the documents.

Is it possible to transfer a bus from zone B to A without modernization?

No, the only legal way is to upgrade to standard Euro 5 (installation of DPF, SCR or switching to gas) with subsequent confirmation in Rosstandart. An alternative is to obtain a temporary permit to enter the New Economic Zone.

What are the fines for entering the NEZ on a zone B bus in Moscow?

In Moscow, there is a fine for entering a low-emission zone (within the Third Transport Ring) on a zone bus B constitutes without permission 5 000 ₽. If the bus is owned by a company, the fine may be increased to 50 000 ₽.

Where can I check if my bus belongs to zone A or B?

Check:

1. PTS (clause 13) or STS (clause 14).
2. Traffic police service VIN or license plate number.
3. Portal Autocode (paid check).

If there is no data - the bus is in the zone B.

Is it possible to travel on toll roads on a zone B bus?

Yes, but the fare will be higher than for zone buses A. For example, on the M-11 Neva highway the difference can reach 50%. See the website for exact rates. Avtodor.
