Adam Roy Triffett, 28, crashed on the East Tamar Highway while travelling at 160km/h around a sweeping bend in 2012.

A blood sample taken from Triffett at the time revealed methamphetamine, oxycodone and cannabis.

One passenger was thrown from the car as it rolled and came to a stop some 60 metres from where it left the highway.

Two other passengers suffered serious injuries.

Triffett was sentenced to two years' with one year non-parole.
