Hello, and welcome to CompSci.ca!
I'm assuming that you have some variables to keep track of each car's position? If so, you're winning half the battle and you should take a good long look at the Collision Detection Tutorial in the Turing Walkthrough.

P.S. I would post my code...but like I said, im very new and i doubt that i did anything the right way so far lol.
All the more reason to post up your code. The best way to learn sometimes is to find out what you did wrong. Finding out what you did wrong is the first step to doing something right.
