A fresh alert was issued today about ice on Oxfordshire's roads.
The B4044 from Eynsham to Oxford was closed this morning following a crash near Red House Farm.
Reports say the road is very icy.
Problems were also reported on the A421 which was closed both ways between Buckingham and Milton Keynes due to a series of accidents.
All roads are reported to be icy in the area.
The A40 between Stokenchurch and High Wycombe is also reported as icy.
Ice has been a problem for drivers in the morning rush-hour for much of this week.
Forecasters say temperatures will rise over the weekend.
