YSK If you were ever in a car accident in a parking lot, or anywhere on private property. Sometimes the police will not come out to the scene because it’s on “private property”. You have a legal right to request that they come to the scene and at least take statements from all the parties involved.

YSK 如果你曾經在停車場，或在私人財產的任何地方發生過車禍。有時警察不會到現場來，因爲這是在 "私人財產 "上。你有法律權利要求他們到現場，至少要向所有相關方錄取證詞。
