How to Choose a Fuel Tanker Truck Compliant with ADR Standards and HG no. 589/2017 in Moldova
The road transport of petroleum products and liquid fuels in the Republic of Moldova is subject to strict technical and safety standards. Under Government Decision no. 589/2017 on the transport of dangerous goods and the European ADR Agreement, every fuel tanker truck sold and operated within the country must meet strict type-approval requirements and active/passive safety specifications.
1. ADR Classification and ANTA Type-Approval (FL vs. AT Vehicles)
In accordance with the regulations of the National Road Transport Agency (ANTA), fuel tanker trucks intended for transporting diesel, gasoline, or kerosene are classified into two main categories:
- FL-type vehicles (Flammable Liquids): Vehicles specially built for transporting liquids with a flash point of no more than 60°C, or flammable gases, in fixed or demountable tanks with a capacity exceeding 1,000 liters. They require electrical wiring protected to anti-deflagration standards, a master power (battery) cut-off switch operable from both inside and outside the cab, and an exhaust system fitted with a spark arrestor.
- AT-type vehicles: Vehicles other than FL or EX/III types, intended for the transport of dangerous goods in tanks.
2. Mandatory Safety Equipment on the Tank
A modern fuel tanker truck must be equipped with automatic systems to prevent accidental spills and the buildup of static electricity:
- Pneumatic bottom valves (Bottom Emergency Valves): Safety valves mounted at the base of each compartment that close automatically in the event of an impact, a fire, or activation of the emergency shut-off button.
- Stage II vapor recovery system: Sealed connectors for recirculating hydrocarbon vapors during loading/unloading at the rack, preventing environmental pollution and explosion hazards.
- Optical overfill prevention system (Overfill Prevention Sensor): Electronic sensors installed in each loading dome, connected to the loading terminal’s pump interlock system.
- Anti-spark grounding: A static discharge bar and a reel with a copper cable and clamp for grounding before unloading operations begin.
3. Sizing Capacity and Chassis Configuration
| Tank Volume | Chassis Configuration | Recommended Use |
|---|---|---|
| 5,000 – 10,000 L | 4×2 Rigid (HOWO / Isuzu) | Fueling agricultural fleets, construction sites, local urban deliveries |
| 14,000 – 22,000 L | 6×4 Rigid (HOWO / Shacman) | Supplying regional PECO fuel stations, intercity routes |
| 38,000 – 49,000 L | 3-Axle ADR Semi-Trailer | International transit and high-capacity transport |
4. Legal Axle Load Limits (ANTA WIM / Road Law No. 509/1995)
Beyond ADR certification, the tank capacity you choose must also match the legal Gross Vehicle Weight (GVW) allowed on public roads in the Republic of Moldova, set out in Annex 3 of Road Law No. 509/1995 and automatically checked at ANTA checkpoints via Weigh-in-Motion (WIM) sensors:
- Rigid 4×2 chassis (5,000 – 10,000 L): legal GVW of 18 tonnes.
- Rigid 6×4 chassis (14,000 – 22,000 L): legal GVW of 25–26 tonnes.
- 3-axle semi-trailer (38,000 – 49,000 L): configurations exceeding standard public-road limits require a Special Transport Authorization (AST), issued under Government Decision No. 326/2022.
An axle load exceeding the legal limit, detected by ANTA’s WIM systems, carries a fine and can jeopardize the ADR Approval Certificate at the periodic technical inspection. Tehnoport’s technical consultants calculate the exact axle mass distribution before delivery, guaranteeing compliance with automated weighing systems on national roads.
