If you are a fan of heavy-duty haulers like Scania, Volvo, or DAF, or if you are in the logistics industry, understanding weight limits is crucial! Here is a breakdown of the Motor Traffic Act regulations in Sri Lanka compared to European Standards.
🇱🇰 Sri Lanka Road Rules (RDA & Motor Traffic Act)
In Sri Lanka, the maximum weight allowed on an axle depends on the number of wheels and the spacing between axles.
1. Axle Load Limits:
Single Axle (2 Wheels): Max 6 Tons (Typically the front steer axle).
Single Axle (4 Wheels): Max 10 Tons (Typically the rear drive axle).
Tandem Axle (8 Wheels): Max 18 Tons (With spacing between 1.0m - 1.4m).
Tri-Axle (12 Wheels): Max 24 Tons.
2. Gross Vehicle Weight (GVW) for Articulated Vehicles:
| Vehicle Configuration | No. of Axles | Max GVW (Tons) |
| Prime Mover + Trailer (2+1) | 3 | 26 |
| Prime Mover + Trailer (2+2) | 4 | 34 |
| Prime Mover + Trailer (3+2) | 5 | 42 |
| Prime Mover + Trailer (3+3) | 6 | 45 |
🇪🇺 European Union (EU) Standards
European limits are governed by EU directives and can be slightly higher due to different road infrastructure and advanced suspension systems.
1. Axle Weight:
Non-Driving Axle: Max 10 Tons.
Driving Axle: Max 11.5 Tons (To minimize road damage).
2. Tandem & Tri-Axle Limits:
Tandem (Spacing 1.3m - 1.8m): 18 Tons (Up to 19 Tons with air suspension).
Tri-Axle (Spacing 1.3m - 1.4m): 24 Tons.
3. Gross Vehicle Weight (GVW):
4-Axle Vehicles: Max 32 Tons.
5/6-Axle Articulated Vehicles: Max 40 Tons.
ISO Container Transport: Up to 44 Tons (for 3-axle prime movers).
🌍 Fun Fact: In Scandinavian countries like Sweden and Finland, special configurations are allowed to carry between 60–76 Tons!
🚦 Important Reminder
Road weight limits are strictly enforced on Expressways and Grade A/B roads. Always check the latest Gazette notifications from the Road Development Authority (RDA) or Traffic Police to stay compliant.
