How far is Charlotte, N.C. from Washington, D.C. if you're driving?

I feel like I’m always a bit late when I brake and stop a bit after the white line or in the crosswalk. While I try to avoid it, my friend told me that it’s legal. Will stopping at a crosswalk result in a ticket?

I bought a car with no credit and the interest rate is about 12%. My uncle told me that I should go to a credit union after paying for a few months to see if I can get a better rate. How do I refinance my car at a credit union?
