A light quadricycle...
The B driving license
A light quadricycle is defined by the fact that its **mass in running order may not exceed 425 kg**, and in the case of electric vehicles, **the weight of the batteries is not included** in that calculation.
Explanation
Light quadricycle: maximum speed and mass
A **light quadricycle** is a type of *microcar*, small and normally for **2 people**.
It has two important limits:
- **Maximum design speed:** **45 km/h**
- **Maximum mass in running order (MOM):** **425 kg**.
An easy way to remember it:
**45 km/h → 4 🚶🚶 5 → 425 kg MOM**
That is, if you think of **45** (the speed) and “put” the **2 people** inside, you get **425 kg**, which is the **maximum mass in running order**.
In addition, for **electric vehicles**, **the weight of the batteries is not taken into account** when calculating that mass in running order.
