A man whose son died in a car crash north of Wellington in 2009 is urging young drivers to obey the road rules and avoid speeding.
Johan Fourie's son, Udo, died when a car driven by his friend James Cupit crossed the centre line and collided with another car.
Cupit's other passenger, Nathan Laurenson, also died and three people were seriously injured.
At the Wellington District Court on Thursday Cupit was sentenced to seven months' home detention and disqualified from driving for two years.
He had been travelling at 100 km/h or more in an 80 km/h zone.
Johan Fourie says he hopes the case will alert other young drivers to the dangers of speeding.
He says speed limits are there to protect people and it's important they're obeyed.
