- 📏 Single axle:
- ❌ Non-driven: 10 t
- ⚙️ Driven: 11.5 t
- 🛞 Tandem (double) axle: according to the distance between axles:
Distance Maximum < 1 m 11.5 t 1 m to < 1.30 m 16 t 1.30 m to < 1.80 m 18 t Twin tyres + air suspension, or each axle ≤ 9.5 t 19 t - ❗ The drive axle must support at least 25% of the vehicle’s total loaded mass
🚚 Maximum Authorized Mass by Truck Type
