Traffic signals and markings1 of 2
What is the primary legal difference between yellow and white pavement markings under Alabama road standards?
The answer
Answer: A. Pavement markings follow strict color conventions on Alabama roadways. Yellow center lines separate traffic lanes traveling in opposite directions on two-way roads. White lines separate traffic lanes moving in the same direction, such as multiple lanes on one-way streets or divided freeways, and designate right-hand road shoulders.
