How long does it take to travel from guwahati to shillong and can i travel by night?

Point Clear how long does it take to travel from guwahati, and is it advisable to make that trip by car in the night? my flight reaches around 7:30 pm in guwahati, and i need to reach shillong that same day. Is it advisable to make that journey at night? Baneberry Yes, you can travel at night, all night military trucks and private trucks run on that highway all night along. Essex Although no one can stop you from traveling at night, I suggest that you travel by day as the area is prone to sporadic violence. It will be a twelve hour journey.
