In Myanmar, there is not much worry about deer, armadillo, and other small animals crossing the road. Those are small dangers! In these parts, it’s the large water buffalo and other cattle that you have to watch out for. These guys are stubborn and will not let vehicles of any sort stop them from crossing a road or grazing along the side.
And believe me; you need to be very observant, not only in rural areas like in Shan State, but even in big cities such as Mandalay. You really do NOT want to challenge one of these big brutes! When they want to cross a road, all traffic comes to a stop. No matter what the traffic police will tell you, these animals remain kings of the road!
