This is a funeral hearse commonly used in Cambodia.
The decors look Chinese and look how fancy and elaborate the details are – hues of gold, red and blue carvings of sbach pattern and amazing dragons on both sides of the vehicle.
The vehicle overtook us at national road number five at a very fast speed. It was empty (no coffin, I mean) but only some people who are probably in-charge of the hearse. I reckon it’s probably running late for its appointment.
