Here is a question I received and answered on the now-defunct website AllExperts.com:
I recently got my drivers license that now allows me to drive alone. I’m still a bit nervous with certain things like changing lanes and left hand turns. When changing lanes how should the cars appear in my mirrors to let me know I have enough space without cutting them off? Someone told me if I can see their head lights in my rear mirror I have enough room, is this correct? I always check my blind spot as well but changing lanes really gives me bad nerves. Any advice is appreciated!
