Usage notes

• The Cambridge Guide to English Usage indicates that sped is for objects in motion (the race car sped) while speeded is used for activities or processes, but notes that the British English convention does not hold in American English.
• Garner's Modern American Usage (2009) indicates that speeded is incorrect, except in the phrasal verb, speed up. Most American usage of speeded conforms to this.
• Sped is about six times more common in American English (COCA) than speeded. Sped is twice as common in UK English (BNC).
