The crash occurred late Wednesday afternoon and closed Highway 97A, south of Enderby for nearly six hours.
UPDATE: The victim has been identified as Peggy (Margaret) Irene Ann Armstrong, 49, of Enderby by BC Coroners Service on Thursday.
Vernon RCMP spokesman Gord Molendyk says a Chevrolet Astro van was seen weaving on the highway, almost hitting a motorcycle just before crossing the centreline and slamming head-on into an oncoming transport truck.
Molendyk says officers want to know if the woman suffered a medical condition or if there were contributing factors that led to the crash.
The van burst into flames after spinning into a nearby field and police say a Good Samaritan shattered a van window to rescue the two-year-old, who was still strapped into his car seat.
The trucker, a 36-year-old Peachland man, barely had time to brace himself before the van hit, and suffered broken wrists as he clutched the steering wheel on impact. (CHNL, CKIZ)
