Double solid yellow lines mean no one may pass from either direction. Crossing them is allowed only when making a left turn, such as entering or leaving a driveway.
A green arrow permits movement only in the direction it points, even while the round red light holds all other movements. You must still yield to pedestrians and to vehicles already in the intersection.
Yellow lines always separate traffic flowing in opposite directions, and a broken yellow line means passing is allowed when the way is clear. White lines mark lanes that carry traffic the same way.
A single dashed line lets you pass or change lanes, but only when the move is safe and does not disrupt other vehicles. If crossing would force another driver to brake or swerve, stay in your lane.
Arrows painted inside a lane show which movements are allowed from it, such as turn only or straight ahead, so you can get into the correct lane early. White edge lines only mark the side of the roadway, and flashing yellow lights signal caution.
With this pair of lines, passing is permitted only for traffic on the broken-line side, and only when it is safe. Traffic on the solid-line side may not cross over to pass.
Tip The line nearest your own lane is the one that decides whether you may pass.
A blinking yellow signal warns you to slow down and watch for cross traffic, pedestrians, and other hazards before you continue. It does not require a stop; a full stop is what a flashing red light demands, and a steady yellow is the one that warns of a coming red.
A single solid white line discourages lane changes but does not forbid them, so you may cross it when traffic conditions call for it, such as to get around an obstruction. Crossing it is not limited to driveways or U-turns.
Directions from a police officer controlling traffic override signs, signals, and pavement markings. If an officer waves you through a red light or tells you to stop at a green one, do what the officer says.
This marking is treated as a barrier between the two directions of traffic. You may not drive across it, and you may not make a left turn or a U-turn over it; such turns are allowed only at a designated opening in the barrier.
A flashing red signal works exactly like a STOP sign: come to a full stop, yield to traffic and pedestrians, and continue only when the way is clear. You must stop every time, whether or not other vehicles are around.
When a traffic light is out, treat the intersection as an all-way stop: stop completely, take turns using the normal right-of-way rules, and go only when it is safe. Slowing without stopping is not enough, and you do not have to wait for every other vehicle to leave first.
A limit line is a solid white stripe that runs across your lane just before an intersection or crosswalk. It shows where your vehicle should stop so that it stays clear of cross traffic and pedestrians.
With no painted stop line, the crosswalk becomes your stopping point: stop before entering it so pedestrians have a clear path. Stopping 50 feet back or at a spot you have guessed is not what the rule requires.
A green arrow gives you a protected movement in the direction it points, but it does not let you ignore anyone still in your path. Before you go, yield to every vehicle, bicyclist, and pedestrian that is already in the intersection.
A solid white line along the right side shows the outer edge of the roadway. When it bends inward toward the middle of the road, the road ahead is narrowing, so be ready to adjust your lane position.
A steady yellow light warns that the signal is about to turn red, so plan to stop before the stop line or crosswalk if you can do it safely. Slamming on the brakes invites a rear-end crash, and stopping inside the intersection blocks cross traffic.
