Road markings compliment the road signs. Markings are painted on the road to guide and regulate the traffic. White is generally used for carriageway (road) markings except those indicating restrictions for which yellow markings are used. White or yellow together with black are used for kerb and object marking.
A dividing line is a road marking formed by a white/yellow line or two parallel white/yellow lies (broken or continous) designed to separate the parts of a road to be used by vehicles travelling in opposite directions.
BROKEN LINE / Broken Line to the left of a Continous Line:
You must keep to the left of these lines. You may cross them to overtake or make a turn, but you must only do so if it is safe.
SINGLE CONTINUOUS LINE
A dividing line is a road marking formed by a white/yellow line or two parallel white/yellow lines (broken or continous) designed to seperate the parts of a road to be used by vehicles travelling in opposite directions.
You must keep to the left and must not cross these lines, unless you have to avoid an obstruction. You are permitted to cross single or double continous lines in order to avoid an obstruction – This does not include a slower moving vehicle or a vehicle stopped in a line of traffic, but may include a fallen tree, a crashed vehicle, or a car that has broken down or is illegally parked.
Before crossing the line, you must have a clear view of the road ahead and it must be safe. You must also be very sure that you cross safely because the onus is on you to take the risk of danger into account.
DIVIDING LAND V/s LANE LINE
A “Lane” is the space between two lines (or a line and the kerb) painted to divide the road into two or more lines of traffic travelling in the same direction. A “Laned” road therefore has at least 2 Lanes. A road without marked lanes is an “Unlaned” road regardless of its width. A “Multi-lane” Road is a one-way road or a two-way road with 2 or more marked lanes that are on the side of the dividing strip or median strip (road divider) where the driver is driving and for the use of vehicles travelling in the same direction.
BROKEN LANE LINE
When lanes are marked by broken lines the driver may change lanes when it is safe to do so by indicating the intention through proper signal.
SOLID LANE LINE
The lanes near intersections are often marked by Solid Lane Lines where no lane changing is permissible. The traffic driving along such lanes bound by solid lines has to move along the same direction or the direction indicated by road marking arrows thus a No-Lane changing zone is created near intersection to prevent last minute change of direction by the traffic, that may obstruct the smooth flow of traffic & cause accidents. The red car in the illustration is committing an offence.
YELLOW EDGE LINES
You must not stop or park your vehicle in any area where a continous yellow edge line is applied even to pick up or set down passengers or goods.
