Java program

I have the following "track", and would like the program to register that the car is crashed, when it is outside the lines. So I got it working for a simple track by using StdDraw.text(size/2, size/2, "You crashed!"), when the terms were met, but am having issues handling this one. If anyone can show me hot to remove the grid outside the track, that would be great too!
