Motorists driving on Highway 140 should be advised of spots of black ice on the roadway, the Oregon Department of Transportation said.

Accidents were reported in Klamath and Jackson counties this morning on the highway.

Drivers are advised to carry chains or have traction tires. Although there is only about 2 inches of roadside snow, below freezing temperatures have caused spots of black ice on the pavement, so drive with caution.

Siskiyou Pass is still bare, as are Interstate 5 passes to the north, including Sexton, Smith Hill and Stage Road.

Spots of ice are reported on Highway 66 at the Green Springs Summit and on Highway 62 in the Prospect and Union Creek areas.
