You want the law ?
well.. its simple...
On the road there are several types of lines (as someone showed on the above)
Short white lines, Long white lines, Solid white Single line, Double white line
Short white lines - You can do whatever the hell you want on the road
Long white lines - indicates that a bend, a road crossing, a solid white single line or a double line is approaching within the next 60m to 100m
You can overtake on these lines, but as a cautionary sign to keep your vehicle on your lane.
Single solid white line - Do not overtake unless the vehicle infront of you is COMPLETELY stopped ... but you CAN double pass (within the same side of the road)
Double solid white lines - You cant overtake, cant do double pass. You have to be in line back to back. Also, you are prohibited to stop your vehicle on the side of the road unless your engine is blown to fuck.. buses cant load passengers and lorries are prohibited to load or unload goods etc. (you get the idea)
NOTE...
you cannot say to the cops that you did not see the white lines (single or double) .. you cannot argue on that point in view of the law.
best thing to do is the go on the SHAPE THEORY or BRIBE THEORY and get out of the damn thing and go home.
But let me tell you a little story on the speeding.
Once.. me and a friend of mine wanted to do a test of this. So we took two cars ( a merc and a beemer) and we did a 1450km round trip around the country where the Merc was doing an average of 100+ at any given moment and breaking every possible road rule. HE was stopped by cops about 8 times and all the times he got away cause of eerrr.. influence... but........ and I on the other hand kept strictly to the enforced speeding limits and road rules... wasnt stopped a single time and actually quite enjoyed my drive in peace.
At every designated stop point in Hotels and other places.. the time difference between him and ME was a maximum of 16 minutes.. that also happened cause my GF (then) wanted to stop to take some pics of an elephant. That was the MAX... othertimes we were just 5 minutes apart.
MORAL of the story... its better to be 5 minutes late than being fucking DEAD on the side of the road wrapped around a tree !
So just fucking keep to the speed limits, obey the god damn road rules and live another day.
