乗せる and 載せる: giving rides and publishing text
Read のせる in rides, loading luggage, and publishing text, including transport contexts where the spellings overlap.
Give someone a ride
友達を車に乗せて、駅まで送りました。 says that someone gave a friend a ride to the station. 乗せる, read のせる, marks the passenger with を and the vehicle with に.
この車にはあと二人乗せられます。 says that the car can take two more people. 乗せられる expresses capacity, not that two people have already boarded.
Load items onto something
台車に箱を載せました。 says that someone loaded boxes onto a cart. 載せる, read のせる, is used for placing objects on a support or conveyance.
The spellings 乗せる and 載せる can overlap when loading luggage into a vehicle. Do not treat “乗 for people, always 載 for objects” as an absolute rule.
Publish text or a photograph
学校の新聞に写真を載せました。 says that someone published a photograph in the school newspaper. This concerns publication, not transporting the photograph.
記事を載せる前に、内容を確認してください。 asks someone to check an article before publishing it. Publication uses 載せる, with を marking the content to appear.
