Quadricycles are European categories of four-wheeled microcars defined by limitations in terms of weight, power and speed. Two categories are defined; knowingly light quadricycles (L6e), and heavy quadricycles (L7e).
In 1992, the European Union published Directive 92/61/EEC which considered that quadricycles fell into the same category as mopeds. Framework Directive 2002/24/EC then refined this definition by distinguishing between light and heavy quadricycles (L6e and L7e categories).
Furthermore, Directive 2006/126 (3rd Driving Licence Directive) establishes a common framework for light quadricycles driving licences. It imposes the same requirements for light quadricycles as for mopeds, including the driving age, for which it recommends 16 years as a minimum. The transposition deadline of the directive is 19 January 2011.
Light quadricycles (L6e)
Light quadricycles (L6e) are defined by Framework Directive 2002/24/EC as: "motor vehicles with four wheels (...) whose unladen mass is not more than 350 kg, not including the mass of the batteries in case of electric vehicles, whose maximum design speed is not more than 45 km/h, and:
- whose engine cylinder capacity does not exceed 50 cm3 for spark (positive) ignition engines, or
- whose maximum net power output does not exceed 4 kW in the case of other (e.g. diesel fuelled) internal combustion engines, or
- whose maximum continuous rated power does not exceed 4 kW in the case of an electric motor.
These vehicles shall fulfil the technical requirements applicable to three-wheel mopeds of category L2e unless specified differently in any of the separate directives".
Heavy quadricycles (L7e)
Quadricycles (L7e), also referred to as Heavy quadricycles, are defined by Framework Directive 2002/24/EC as motor vehicles with four wheels "other than those referred to (as light quadricycles), whose unladen mass is not more than 400 kg (category L7e) (550 kg for vehicles intended for carrying goods), not including the mass of batteries in the case of electric vehicles, with a design payload not more than 200 kg (passenger) or 1000 kg (goods), and whose maximum net engine power does not exceed 15 kW. These vehicles shall be considered to be motor tricycles and shall fulfil the technical requirements applicable to motor tricycles of category L5e unless specified differently in any of the separate Directives".
Safety during collisions
In a collision the occupants of a heavy vehicle will, on average, suffer fewer and less serious injuries than the occupants of a lighter vehicle. An accident in a 2000 lb (900 kg) vehicle will on average cause about 50% more injuries to its occupants than a 3000 lb (1350 kg) vehicle. That said, since the speed the vehicle can attain is quite minimal compared to regular cars, the collisions will tend to be lighter overall - at least for collisions that are caused by the driver of the motorised quadricycle (not for collisions in which the collision is caused by the other party).
