Who’s to blame here?

I was going through the Yasa website when I noticed this piece of news:

A 14 year old young man, called Mehdi Hamdan, was killed yesterday after he lost control of his car on the Nabatieh-Zebdeen highway. His father heads the Sayyid Mohammad Hussein Fadlallah social services bureau in Nabatieh.

While one cannot but feel sorry for his parents’ loss, the victim is only 14 years old and was driving around without a permit on the highway and jeopardizing people’s lives. Who’s to blame in that case? Is it wrong to hold the parents accountable in case they were letting him drive their car? How about the police? Don’t they patrol the highway in that area?
