Lane positions that straddle the lines on the roadway typically include the left and right edges of each lane, where vehicles may partially occupy both the lane and the adjacent space. This can occur during lane changes, merging, or when a vehicle is slightly off-center in its lane. Straddling lines can also indicate a need for caution, as it may suggest that a vehicle is not fully within its designated lane. Proper lane discipline is important for safety and traffic flow.
Usually no. If changing lanes is prohibited on a particular bridge, there will be signs to indicate it,and the lines on the roadway will be solid.
Lanes on roadways are typically marked with white or yellow lines. White lines indicate lanes going in the same direction or the edges of the road, while yellow lines separate lanes of traffic moving in opposite directions. The specific colors and patterns can vary by region and roadway type, but these are the most common standards.
The pattern of yellow lines on the roadway indicates restrictions for passing and changing lanes. Solid yellow lines usually mean no passing, while dashed yellow lines allow passing with caution. It is important to obey these markings to ensure safety on the road.
That mean cannot park there . Another View: If it is in center of the roadway separating opposing lanes of travel it means NO PASSING.
In civilian vehicular traffic, broken (or "dotted") lines are used to divide major roadways into lanes. On divided roadways (with a central barrier or turn lane) of 4 lanes or more, broken lines are used between 2 adjacent lanes, when & where it is permitted to change lanes with care. On controlled-access highways (freeways, turnpikes etc), broken lines are also used to separate through- lanes from on and off-ramps. In many jurisdictions, a thicker broken line is used to make that separation distinctive. On a 2-lane divided roadway (where opposing traffic exists with no physical barrier or turn lane), broken lines are used between the lanes (i.e. centre of the roadway) to identify passing zones. When the centre line is double, the broken line indicates on which side it is permitted to overtake with care. When the centre line is single and broken, it is permitted to overtake with care on both sides. On roadways with High Occupancy Vehicle lanes ("HOV" lanes), broken lines are used to indicate zones where it is permitted to enter or exit the HOV lane from/to the regular roadway. The use of solid lines is much more ubiquitous. On multi-lane roadways, they are used to identify the inner & outer road shoulders, or can also be used between lanes in no-passing zones (i.e. construction zones etc). On 2-lane divided highway, solid lines indicate the road shoulder in each direction, and are also used between the 2 lanes (centre of the roadway) to indicate no-passing zones, either in one direction (solid/broken) or in both directions (double or single solid). At intersections, solid lines are used to indicate stop lines and pedestrian walkways. On shared roadways (vehicle/bicycle, vehicle/pedestrian), solid lines are used to separate vehicle lanes from the bicycle/pedestrian lanes. On HOV lane roadways, solid lines are used to separate regular lanes from HOV lanes in areas where entering or exiting the HOV lane is not permitted. In many jurisdictions, especially those which commonly receive snow in winter, broken lines between lanes of multi-lane roadways are usually white, and the solid lines indicating the inner & outer shoulders are often of different colours, usually yellow for inner & white for outer. Both shoulder lines are often yellow on 2-lane divided roadways. While police may not necessarilly always ticket motorists who straddle lane/shoulder lines, or who pass when the centre line is solid, such disregard which leads to an accident (including close calls) will most certainly result in charges.
They mark the edge of the carriageway/roadway.
same direction, if the lines are broken this means you are allowed to change lanes. If the line or lines are solid, you are not supposed to change lanes.
Two white (or yellow) parallel lines down the center of a roadway signify No Passing allowed.
You are not supposed to ride on the lines, they divide the lanes.
(in the US) They indicate a no passing zone. The white lines indicate multiple lanes of travel in the same direction, while the yellow lines indicate opposing lanes of travel.
Yes, drivers are generally required to stay within the designated lanes on roadways marked with white or yellow lines, as these lines indicate the boundaries of the lanes and help maintain traffic flow and safety.
The Sydney Harbour Bridge carries eight lanes of vehicular traffic. There are also two train lines, a pedestrian footpath and a cycleway. The width of the bridge is almost 49 metres.
