Questionwhat is a white curb mean
AnswerYou ask a good question. In simple, you should ask your parents or a driving teacher, for I am probably going to leave out some information. It also varies with states. Near the curb, you should see a sign. Even if no sign, the curb color tells something.
Read the following websites for more information and than ask your parents and a driving teacher.

Good luck and ask follow ups. Those sites are not perfect. Some laws also vary by states.
