How to say "trailer" in Japanese

• トレーラーCommon
  nounCovers the vehicle sense only: a trailer towed behind a car or truck, as when hauling a boat or heavy load. For film previews it is not the word — use 予告編.
  トレーラーがその車くるまについている。↗

  The trailer goes with the car.
• 予告編よこくへんCommon
  nounThe word for a film or TV trailer: a short preview advertising an upcoming movie or show. This, not トレーラー, is what you want for the cinema sense.
• 予告よこくCommon
  nounAn abbreviation of 予告編 covering the same film and TV trailer sense. Since 予告 by itself can also mean advance notice, 予告編 is the more explicit choice when you mean a trailer.

「トレーラー」 is the towed vehicle; 予告編 is the film or TV preview, and 予告 is its abbreviation — pick 「トレーラー」 for transport and 予告編 for movie previews.
