The crash happened on the Coquihalla Highway north of Merritt early Sunday, the Canadian Broadcasting Corp. reported.
"At one o'clock a.m., it was reported an incident took place with one of our coaches," said Timothy Stokes, a spokesperson for Greyhound. "There were approximately 42 people on board at the time. No serious injuries reported. As recommended by the RCMP, we did transport those 42 passengers on a second bus to the hospital as a precaution."
Stokes said it was unclear exactly how many passengers were injured.
