The warnings follow a Met Office forecast of another spell of persistent heavy rain and windy weather today and into Wednesday, which could affect driving conditions.
Heavy rain is likely to affect much of the country, especially in the south and west of England.
In addition, strong winds are expected to affect the south, particularly exposed parts of Kent and Sussex, around the middle of the day.
Drivers are reminded that rain and spray can reduce visibility and when the road is wet it can take up to twice as long to stop.
If your vehicle loses its grip, or "aquaplanes" on surface water, take your foot off the accelerator to slow down. Don't brake or steer suddenly because you will have no control of the steering or brakes.
Surface water may affect motorways and major A-roads so we advise drivers to move slowly through any standing water and test their brakes once they're through before continuing to drive.
Drivers are also advised to carry warm clothing and an emergency pack, which includes food and water, boots, de-icer, a torch, a spade if snow is forecast, and to make sure they have plenty of fuel for your journey.
