Georgia has a unique set of road markings.

In Georgia, the road markings are consistent with national standards and regulations, which means they align with what drivers would expect based on driving in other states. The state does not have a unique set of road markings that distinguish it from the rest of the country. This uniformity is important for ensuring that drivers from other states can understand and follow the road rules without confusion. This consistency also aids in fostering safer driving conditions across all regions, whether urban, suburban, or rural.

The other choices imply that there might be special conditions or exceptions for road markings in Georgia, but that is not the case when considering the overall standards applied statewide. The state uses conventional markings that adhere to established guidelines.
