Quadricycle (EU vehicle classification)

There is a licence category called AM-121, introduced in 2013, separately for quadricycles, although M-class (moped) licenses issued before 2013 qualify as well.

[9] Certain quadricycles can be driven on a "road safety certificate" category of drivers licence, which is available to people 14 years or older.

[10] The quadricycle must be speed limited to 45 km/h (28 mph) and have a petrol motor up to 50 cc (3.1 cu in) or be electric or diesel powered up to 4 kW (5.4 hp).

[citation needed] A Light quadricycle, a micro car with less than 6kW of power, and an unladen mass no more than 425 kg can be driven on a full bike licence.

Anything more powerful or more heavy requires a full car licence to be legally driven as a vehicle on UK roads.
