If you have held a category B driving licence for more than three years, are you permitted to drive motorcycles?

Why this is the correct answer

According to Spanish traffic law, holders of a category B (car) licence who have held it for more than three years are permitted to ride motorcycles with an engine capacity of up to 125 cc, a maximum power of 11 kW (15 CV), and a power-to-weight ratio not exceeding 0.1 kW/kg. These are the same limits that apply to the A1 motorcycle licence category. This authorisation is valid only within Spain; to ride a 125 cc motorcycle in another EU country, you would need a full A1 licence. Important: if you have held your B licence for LESS than three years, you are NOT allowed to ride any motorcycle with it. In that case, you must either obtain a specific motorcycle licence (A1, A2 or A) or wait until three years have passed since your B licence was issued. Riding a motorcycle without meeting this requirement can result in a fine of 500 euros, the loss of 4 points and immobilisation of the vehicle.
