Motorists were warned to take care on the Island's roads again this morning (Wednesday).
Slippery conditions were reported in all areas, following sub-zero temperatures overnight, and there was said to be black ice in places.
Gritters were out on some routes.
There was a single vehicle accident at Creg Willey's Hill near Glen Helen, which blocked the road for a time.
The road was also blocked after an accident at Glen Mooar, a mile south of Kirk Michael.
