I appreciate the initiative taken by you. I believe the overall traffic conditions in Quetta arre no different than in any other city of Pakistan.
I regularly travel on highway on my car and come across a lot of nuisance. Traffic conditions are so worse in our country that even to think of an improvement we need to start over again. In the developed countries the first lesson they give you is that the pedestrian has the first right of way but in our country a pedestrian is the most vulnerable on road where no one cares for him.
The most serious issue is that even our traffic police does not know the ABC of traffic laws. I regularly come across patrolling police vans that run at hardly 10km/h speed on highway with 80km/h speed limit. Such vans and always cause trouble for overtaking especially when another vehicle is coming from front. The point is, no one observes the traffic signals. When the road sign says speed limit 30km/h then ebveryone is bound to go on that speed and if it says 100km/h (as on highways) then everyone is bound to go go on that speed. this is why in the developed world we do not see slow moving vehicles on highways.
For motorcycle riders who have to ride on the city roads, it becomes of utmost importance that they observe speed limit, wear helmet at least and have got side mirrors on the bike and also observe the laws of the lane. To avoid accident never tailgate anyone, nor let anyone tailgate you. Tailgating is an open invitation to accident. Unfortunately it is this very common mistake almost every biker commits on the city roads.
I have several other points but that may make it a lengthy and boring reply I shall conclude here by saying that no system can work properly unless you adopt it fully. Observing some traffic laws and neglecting others is of no use. Our highways themselves are a major cause of accidents, consider the highways that pass through villages/inhabited areas where animals can crop up any time. Bad quality roads, roads with no painted lines/lane, blind dividers to name the few are some of the major factors that cause accidents.
Safety always comes first, but first of all we need to have safer roads. Other than motorways, I do not reckon any road/highway as a safe road in Pakistan.
