The turn lane is used for making turns from or into the roadway or when making a U-turn when permitted by law. A stop line is a white line painted across a lane at an intersection. The line is usually four ft. before the crosswalk in an urban area. It shows where you must stop for a STOP sign or red light. You must bring your vehicle to a halt before any part of it crosses the line.
Crosswalk lines are white lines painted across the entire width of the pavement.
Sometimes the inside area is marked with white diagonal lines for added visibility. Crosswalks are sometimes in the middle of the block in residential areas, and in this case a pedestrian crossing sign is located at the white lines. Solid white or yellow lines are sometimes used to channel traffic around a hazard. A double solid white line prohibits lane changing. Curb markings, fire lanes and pavement markings may be designated as No Parking areas by local authorities.
