A man faces a maximum of 14 years jail after being accused of being behind the wheel in a fatal crash on Queensland's Sunshine Coast.

The Nambour man, 39, was on Monday charged over the single-car crash at Witta on July 13, when a 22-year-old passenger died after the car smashed into trees.

Police say the man is accused of dangerous driving causing death while adversely affected by a substance - a charge that carries a maximum of 14 years in jail.

He is scheduled to appear before the Maroochydore Magistrates Court on September 24.

Earlier on Monday, a 46-year-old man died when his car collided with a truck at a Bruce Highway on-ramp in Maryborough West about 6.30am.

The truck driver, 62, suffered shoulder injuries and was taken to hospital in a stable condition.

More than 170 people have been killed on Queensland roads this year, about 20 more deaths than at the same time last year.
