Thick fog covered the Thames Valley this morning, with many drivers having a slower commute to work.
Thames Valley Police (TVP) has reminded drivers to put their car lights on when encountering fog.
A spokesperson from TVP said: "Please ensure you travel safely today.
"Fog is reducing visibility so please check your lights are on when in areas of reduced visibility.
"Consider using fog lights if visibility is greatly reduced but remember to turn off your fog lights if not needed.
"Stay safe out there."
The Met Office put out a moderate fog warning this morning and stated that freezing fog patches would clear throughout the morning - slowly in some rural river valleys, then most areas seeing long spells of sunshine.
Fog is expected to continue tomorrow with fog expected to reform throughout the night as cloud cover thickens.
