How is the blood money to be paid for three young men who died in a car accident as a result of a truck colliding with their car, and what is the amount of this blood money?

If the error was from the truck driver, then the blood money for those killed is on him and his 'Aqilah (male relatives on the father's side).

If the error was shared between the drivers, the blood money is distributed between their 'Aqilahs according to the proportion of the error, and specialists determine this.

If the driver of the other car was solely at fault and the truck driver could not avoid the accident, then there is no blood money or expiation on the truck driver. Rather, the blood money and expiation are on the driver of the car who was at fault and his 'Aqilah.
