Two men involved in separate car crashes across the Easter holiday are both in a stable condition at the Launceston General Hospital.
A 21-year-old Tongan man was involved in a single-vehicle crash at Mole Creek about 5am on Good Friday.
Tasmania Police said the man lost control of his Toyota Camry and swerved to the incorrect side of Mole Creek Road.
He then overcorrected and slid, hitting a power pole.
A fatal crash also took place just after midnight at Birralee on Easter Saturday.
An 18-year-old passenger died at the scene, and the 27-year-old driver was taken to the Launceston General Hospital with head injuries.
Police said investigations indicated the Mitsubishi Triton being driven by the 27-year-old lost control on a right-hand bend and crossed onto the incorrect side of the road before hitting a power pole.
Investigating are taking place to see if alcohol and speed were a factor in the crash.
Tasmania Police reminded drivers that winter conditions can create changed road conditions, and when combined with increased traffic flow during Easter, require a higher level of concentration.
Drivers are urged to be conscious of their speed, wear their seat belt, and not to use their mobile phones when driving.
