A blast of freezing weather has been sweeping across the UK, bringing disruption to evening travellers.
Large parts of the UK have already been hit by heavy snow, which has now started to affect southern areas, with warnings of snow and ice during this evening's rush hour.
Long delays are reported on many major roads in London due to snow, including queues in both directions on the M25.
BBC Weather's John Hammond warned that the temperature "will drop like a stone" after midnight resulting in icy conditions.
Another band of sleet and snow is forecast to hit overnight in Scotland, and then the south east of England during tomorrow morning's rush hour, he said.
