A L-plate driver and two others were killed after a collision near Byron Bay last night.
The men died when the car they were travelling in struck a B-double semi-trailer about 8.15pm yesterday.
Police said it appeared the learner driver passed through a give-way sign when merging onto the Pacific Highway from Johnston Lane, north of Byron Bay.
"It appears the three deceased young men were travelling in a Subaru Liberty sedan," duty officer Inspector Jim Kain said.
"They were turning from Johnston Lane onto the highway.
"There is some suggestion the driver may have driven through a give-way sign into the path of a B-double semi-trailer, which was travelling south on the highway."
The L-plater was a 23-year-old male. His male passengers were 22 and 25 years old.
All three were from Ocean Shores, north of Brunswick Heads.
The driver of the truck was uninjured and assisted police.
The accident follows the death of two 20-year-old drivers on south-east Queensland roads yesterday.
A woman died when her car hit a tree at Chambers Flat, south of Brisbane, about 4.15pm.
A 20-year-old man from Beerwah, north of Brisbane, died while riding a motorbike at Forest Glen on the Gold Coast.
He crashed the 2008 Suzuki on the Eudlo Creek Bridge at the Bruce Highway about 6am.
