If you are on the pike, the speed limit for all lines regardless of what you are doing is b/n 55 to 65, if you are driving more than that, you are breaking the law. but if you need some advice from me how-to drive in MA, since I have been doing this for living for 27 years. first of all mind your business that means don't make rules for other motorist, keep your speed limit 5 miles more that the speed limit. when passing cars, on their left or right it doesn't matter, time it yourself don't move Infront of their face. start the move then signal to keep them shout. or they will block you. and if you really want to go fast use far right lane, for most drivers avoid it. if you follow these rules, you will save yourself from a trip to the doctor and a mild Storke in the middle of the highway.
