An intense, early spring snowstorm made travel treacherous on Highway 97C, the Okanagan Connector late Thursday.
Conditions were so extreme that Kelowna Regional RCMP urged drivers to stay off the highway or consider another route.
Cpl. Jesse O’Donaghey says one truck jack-knifed near the Pennask Summit, blocking the westbound lanes west of Peachland, and other trucks got stuck in the snowy, slushy conditions.
Police were not aware of any injuries caused in the crashes.
DriveBC lists conditions on Highway 97C as slushy and slippery with sections of compact snow at the highest elevations.
Highway 97C is one of many in the southern Interior and northern B.C., where snow tires are mandatory until April 30, one month longer than regulations covering most other highways.
DriveBC weather cams also show snow has fallen on the Coquihalla highway.
