A man, wearing a green shirt and dark trousers, is working on the back of a large white truck. The truck has a tall, rusty exhaust pipe extending upwards. The man appears to be focused on the engine area at the rear of the truck. A white trailer is parked to the left of the truck. Other trucks are visible in the background under a clear, blue sky. The license plate of the truck starts with "TH 159". The man appears to be tightening something.
