第一个步骤是，查看给你发ticket的理由是什么。

根据这个理由，去查本地的baylaw。

注意，虽然交通法规是省里管的，但是停车罚单是市里管的。所以，要查的不说安省交通法规。换句话说，安省交规规定是路口九米内禁止停车，有红绿灯增加到15米。这个不会成为市里给你开停车罚单的依据。

拿最近发帖网友的情况做例子。那个罚单上写的是，Parking vehicle within 5 meters of intersection。

假设这个网友住在密西沙加，找到当地的parking bylaw.

用5m或者intersection搜索，可以找到相关条款。

PARKING

(7) within the lateral lines of an intersection or within five (5) metres of the lateral lines to an intersection;

涉及到细节问题，还可以找到 intersection的定义。

“intersection” means the area embraced within the prolongation or connection of the lateral curb lines or, if none, then of the lateral boundary lines of two or more highways that join one another at an angle, whether or not one highway crosses the other;

其中提到highway, 也可以查定义。
