This is Thailand, when Thai's see a bad situation unfolding in front of them on the road, they usually floor it! Plus, after re-watching the video, it seems this officers motorcycle skills were pretty poor, he laid the bike down on purpose before ever getting to the truck. In fact, there was no collision between the bike and the truck, it was the officer himself that collided with the truck. The accident was easily avoidable if he didn't panic, too much braking and laid the bike down. We practiced panic stops (avoidance skills) like crazy in the MSF course, just for these types of situations, they should probably send motorcycle officers to special courses as well. I actually loved that part of the course the most, the trainer would tell us to go either right or left just before reaching him, while standing in front of a set of cones (pretend stopped bus) at the last second while we are at speed, then we had to stop as fast as we could to the side of the fake bus.
