any can help my correct it .. thanks

i was in a rush that morning because i slept in. it is because either my alarm doesn't work or i accidentally press the wrong button. then i drove off as usual.
i did a turn into a small street with i think around 30km/h, and suddenly there was a police officer stood right in front of me. i thought he is trying to catch speeding or danger driver, therefore i decided to do another turn and get in the freeway

One day I was in a rush because I slept in that morning. This is because either my alarm clock didn't work or I have accidentally press the wrong button. But when I drove into a small street on my car, I suddenly saw a police officer standing further on the street. I think he's there to catch speeding cars and dangerous drivers. I think I was driving at 30 miles per hour then, so I turned quickly on the next turn to get on the freeway.

"I press wrong button"之後唔須要強調我就好似平常咁揸車出去
同埋" I saw a police officer stood in front me".如果個警察已經"企"左係你架車前面而你又已經超速,咁講其實係佢已經要停你架車. 應該要話你見到街遠d/前d有個警察係度睇下有冇人超速.
基本上都只係呢兩點文法上最怪,其他都只係小小字面上既問題
