CLEARLAKE OAKS – A Friday afternoon collision may have been caused by driving under the influence.

The California Highway Patrol incident logs reported that a collision between a semi truck and a small pickup took place at about 2:18 p.m. on eastbound Highway 20 at Keys Boulevard.

The CHP reported there were major injuries involved in the crash, but it was not clear how many people may have been injured or were transported to area hospitals.

At least one subject was transported to Redbud Hospital, where a forced blood draw – usually done when alcohol or drugs are suspected – was to have taken place, according to the CHP logs.

No further information was available from CHP Friday evening.
