2.3 Pavement Markings & Lane Use

2.3 Pavement Markings & Lane Use

Pavement markings are painted directly on the road surface to guide, warn, and regulate drivers. They tell you where to drive, when it is safe to pass, and where special rules apply. The two most important concepts to understand are line color and line pattern.

Line Colors: Yellow vs. White

Yellow Lines: Yellow lines separate traffic moving in opposite directions (two-way roads). They also mark the left edge of divided highways and one-way streets.

White Lines: White lines separate traffic moving in the same direction (multi-lane roads). They also mark the right edge of the roadway, pedestrian crosswalks, and stop lines.

Line Patterns: Broken vs. Solid

Broken (Dashed) Lines: A broken line means you are permitted to cross it. If it is a broken yellow line, you may cross it to pass a slower vehicle ahead, provided it is safe and the oncoming lane is clear. If it is a broken white line, you may cross it to change lanes.

Solid Lines: A solid line generally means you should not cross it, or that crossing is strictly prohibited.

Specific Yellow Line Markings

• Single Broken Yellow Line: Traffic is moving in opposite directions. You may pass on the left if the road ahead is clear.
• Solid Yellow Line alongside a Broken Yellow Line: If the broken line is on your side, you may pass. If the solid line is on your side, you may not pass.
• Double Solid Yellow Lines: Passing is strictly prohibited in both directions. You may not cross these lines to pass. You may only cross them if you are turning left into a driveway or side street, and only if it is safe to do so.
• Shared Center Turn Lane: This lane is in the middle of a two-way street and is marked on both sides by a solid yellow line on the outside and a broken yellow line on the inside. This lane is strictly for making left turns. You may not use it for passing, and you may not travel in it for long distances (generally no more than a few hundred feet).

Specific White Line Markings

• Single Broken White Line: Separates lanes of traffic moving in the same direction. You may cross it to change lanes when safe.
• Single Solid White Line: Separates lanes of traffic moving in the same direction. It indicates that changing lanes is discouraged or potentially dangerous, though not strictly illegal in Florida unless prohibited by a sign. It is also used to mark the right edge of the roadway (the fog line).
• Double Solid White Lines: Crossing a double solid white line is strictly prohibited. You are not allowed to change lanes across these lines. They are often used to separate standard lanes from HOV lanes or express lanes.
• Stop Lines: Wide white lines painted across a traffic lane indicating exactly where you must stop for a stop sign or red light.
• Crosswalks: Defined by solid white lines or a series of white blocks. You must always yield to pedestrians in a crosswalk.

Special Lane Markings

High Occupancy Vehicle (HOV) Lanes

HOV lanes, also known as carpool lanes, are marked with a large white diamond painted on the pavement, often accompanied by signs. These lanes are restricted during specified hours for use only by vehicles carrying a minimum number of occupants (usually 2 or more). Motorcycles and certain low-emission vehicles (with the proper decal) are also often permitted regardless of the number of occupants.

Turn Lane Arrows

Lanes designated exclusively for turning are marked with white arrows pointing in the direction of the turn. If a lane is marked with a curved arrow and the word "ONLY," you must turn in that direction if you are in that lane. If the lane features a curved arrow and a straight arrow, you may either turn or go straight.

Bicycle Lanes

Bicycle lanes are portions of the roadway intended for the exclusive use of bicycles. They are marked with solid white lines and a bicycle symbol. You may not drive in a bicycle lane except when you need to cross it to make a turn, enter or exit a driveway, or park (if parking is permitted). Before crossing a bicycle lane, you must yield to any bicyclists in the lane.

Reversible Lanes

Some highways have reversible lanes to help handle heavy rush-hour traffic. The direction of traffic in these lanes changes at different times of the day. They are marked by special double dashed yellow lines and are controlled by overhead Lane Use Control Signals (the red X and green arrow discussed in Section 2.1). Never enter a reversible lane unless the overhead signal clearly indicates it is open for your direction of travel.
