This happened in Paniqui, Tarlac, the Philippines on April 10, 2019, where there was an collision between a truck with a group of bikers. Four bikers died on the spot with a bunch more seriously injured.

The story is that a 10 wheeler truck swerved into the oncoming lane, ramming the bikers as they rode in the opposite direction. It was supposed to be a holiday getaway for the group, wherein they planned to visit Churches in the region for Easter.

The unconfirmed claim is the truck driver dosed off.

Props to Best Gore member @alienworm12 for the pics and video. The first minute and a half of the video is just the bikers riding. The footage then cuts into the aftermath of the accident. The moment of the crash is not on there. Skip to 1:33 to get past the riding:
