Cpl Cheryl Bush said the situation is very serious due to the contents that were being hauled.
"The tanker truck contains an explosive material, therefore the highway has been closed in both directions until further notice," she told CBC News just before 3:30 p.m. PT. "Police are currently assessing the situation and determining evacuation requirements for residents in the area."
RCMP said it appears the driver was able to unhook the trailer from the burning cab.
