The accident was in Maha Sarakham, not sure what road. We had ridden with the group for two days and speeds were moderate nothing over 100 for the most part. We had split up from the group and headed back to Udon about 30 mins prior to the accident as my wife was ill. He explained the accident that he was passing a group vehicles three cars and a 18 wheeler. Just as he got to the back of the truck, The driver signaled for a right turn at an immediate road. So the rider locked the front brake, knowing he was going to go down. That being a better alternative then hitting the truck. The guy was wearing full safety gear. I always try to learn from my mistakes and share them with others. I also try to learn from others mistakes. This was an odd one he had a small case he carried around his neck with his phone and camera. The impact with the camera broke two ribs in both have two fractures each. Other then that he would walked away with a small raspberry on his right knee.
