You just can't go past the white line. That's what they watch for..my daughter took it not long ago and the instructor told her to pull up past it cause the instructor could not see for oncoming traffic. So best thing is to not go past it and if your not able to see from where your at, let your instructor know so they give you permission to pull up more. Hope this helps!
If you are on the white line or between you should be good
