Axle load limits are a top concern for Vietnamese trucking companies and drivers. Proper compliance ensures traffic safety, extends road infrastructure lifespan, and helps avoid unnecessary fines. The Ministry of Transport recently issued Circular 39/2024/TT-BGTVT, effective early 2025, detailing axle load limits and related issues. This article from Xe Tải Mỹ Đình analyzes the Circular’s key content, focusing on axle load limits for clear understanding.
1. Detailed Axle Load Regulations Under Circular 39/2024/TT-BGTVT
Circular 39/2024/TT-BGTVT clearly defines load limits for each axle type and axle group, aiding vehicle owners and drivers in compliance. Below are detailed regulations on axle load limits in Article 14 of the Circular:
1.1. Single Axle and Tandem Axle Group Load Limits
For standard trucks, axle load limits are divided into two main types: single axles and tandem axle groups.
-
Single Axle: The allowable load on each single axle must not exceed 10 tons. This applies to individual axles, not part of a group.
-
Tandem Axle Group: For tandem axle groups (two axles close together), the allowable load depends on the distance (d) between the axle centers. Specifically:
- d ≤ 1.0 meter: The tandem axle group load must not exceed 11 tons.
- 1.0 meter < d ≤ 1.3 meters: The tandem axle group load must not exceed 16 tons.
- d > 1.3 meters: The tandem axle group load must not exceed 18 tons.
This distance-based division ensures proper load distribution on the road surface, minimizing negative impacts on traffic infrastructure.
1.2. Tridem Axle Group Load Limits
For trucks with more complex configurations using tridem axle groups (three axles close together), axle load regulations are adjusted to suit the vehicle’s design and load capacity. Similar to tandem axle groups, the allowable load for tridem axle groups depends on the distance (d) between two adjacent axle centers:
- d ≤ 1.3 meters: The tridem axle group load must not exceed 21 tons.
- d > 1.3 meters: The tridem axle group load must not exceed 24 tons.
This ensures that even with multi-axle vehicles, the load is controlled within safe limits, preventing road and bridge overloads.

2. General Cargo Loading Regulations Under Circular 39/2024/TT-BGTVT
Besides axle load regulations, Circular 39/2024/TT-BGTVT addresses general cargo loading regulations on road vehicles (Article 13). These regulations ensure safety during transport and prevent improper loading, causing hazards or exceeding allowable loads.
Key points in cargo loading regulations include:
- Selecting Suitable Vehicles: Transport companies must choose vehicles with dimensions and load capacities appropriate for the goods being transported.
- Complying with Load Regulations: Loading must not exceed the vehicle’s allowable total mass, axle load limits, and other dimensional limits.
- Loading Cargo Neatly and Securely: Cargo must be loaded neatly, evenly distributed, and carefully secured to prevent shifting or spillage during transport.
- Ensuring Safety and Environmental Protection: Loading must not obstruct the driver’s view, obscure lights or license plates, and must ensure environmental hygiene.
Conclusion:
Circular 39/2024/TT-BGTVT is a key legal document detailing axle load regulations and road transport-related issues. Understanding and complying with these regulations not only helps businesses and drivers avoid legal violations but also contributes to protecting traffic infrastructure and ensuring safety for all road users.
