求一句英文翻译：（刚才在那个十字路口会车的时候，你让行于那辆汽校的学员车，...）

When we met the car at the crossroad just now, you let the student car of driver training school go first. While if it's a normal car such as privite car, who has the priority to go first? The reason why i ask so is because i want to learn more about traffic code before i take part in the driving license test soon.

翻译 :(口语话)

while you met the student driver at the crossing way, let them go first. But who can go first if both are pravite cars? I just wannna know the rules cause i am gonna take the text of driver's license.

补充: 一般在stop sign,谁先到,谁先走.
