Some roadways are designed to accommodate different traffic demands during the day through the use of a reversible lane system. Appropriate travel lanes on a roadway utilizing a reversible lane system are indicated

No travel allowed in this lane in the direction you are going 

When a road is crossed by a railroad crossing, the pavement is usually marked with a large X and two R’s. At

railroad crossings, a yellow line is always placed on the right side of the center line to prevent passing. The

crossing is sometimes equipped with control arms and/or emergency lights, to warn drivers of approaching

trains. The driver of the vehicle must stop if warning signals indicate a train is approaching.

Single  Lines

Double White Lines

These single, solid yellow lines on two-lane roads indicate zones where passing is prohibited. They will

be located on the right of the broken yellow line when they apply to the lane in which you are traveling.

In some instances, both yellow lines will be solid, indicating it is not safe for passing in either direction.

These are double white line (dashed or solid) pavement markings on roadways that indicate where

vehicles can or cannot cross to access the adjacent lane. When the double white lines are dashed,

vehicles are allowed to cross over to the adjacent lane. When the double white lines are solid, lane

changes are prohibited.

These are the solid white lines along the side of the pavement. They serve as safety guides, especially at

night when it is difficult to see the edge of the road. A yellow edge line may be used on the left side to warn

of narrow or raised medians.

These are the white dashes that mark the individual lanes of travel on streets and highways having more than

one lane for traffic moving in the same direction.

When there are four or more lanes with traffic moving in opposite directions, two solid yellow lines mark

the center of the roadway. You may cross these lines only to make a left turn into or from an alley, private

road, driveway, or another street. When traveling on a multi-lane road, stay in the right lane except to pass

other vehicles traveling in the same direction.

These lanes, bordered by solid yellow and/or broken yellow lines, is in the center of many streets and highways to make left turns. A motorist desiring to turn left should proceed to the turn lane just prior to making a left turn.

Georgia law prohibits the use of this lane for any purpose other than making a left turn. You may enter this lane no more than 300 feet from the location of the left turn.

When a turning lane is provided for vehicles traveling in both directions, you should use extreme caution before entering the turning lane to make a left turn. There may be a vehicle traveling in the opposite direction also

entering the turning lane to make a left turn. This is especially problematic in congested areas.

These are solid white lines typically located between the farthest right traffic lane and the curb or edge of the roadway. If there is a right-turn-only lane present, the bicycle lane will be located to the left of the right-turn-only lane in order to safely accommodate bicycles traveling straight through the intersection. Bicycle lanes may also be marked with painted symbols of a bicycle. Drivers of motor vehicles are prohibited from driving or parking in

the bicycle lane, except to cross over it to make a turn. When crossing over a bicycle lane to make a turn, motorists must yield to bicyclists that are present.

These markings, created by diagonal yellow lines, are on streets and highways indicating that the road is narrowing or there is an obstruction on the roadway. The area is similar to a triangle with solid yellow diagonal lines within

the outside lines. Always keep to the right of these markings.
