Drivers are being warned of challenging motoring conditions as Storm Gertrude continues to wreak havoc across much of Britain.
They face torrential rain, ice, snow and further strong winds on Friday (January 29), according to weather forecasters.
Winds in excess of 90mph have already hit western Scotland with overturned vehicles requiring breakdown services.
RAC spokesman Rod Dennis said: "Strong, gusty winds are leading to hazardous conditions on many highland and lowland routes in Scotland. Drivers will need to take extreme care and slow down, especially on more exposed stretches of road.
"On Saturday, high winds will be combined with wintry showers, making driving conditions more treacherous. Disruption on the roads is likely, so motorists should listen for and heed all local weather warnings, expect their journeys to take longer than usual and, when out on the road, take particular care overtaking other motorists."
Strong winds have le ft many homes without power and caused disruption to traffic and public transport routes.
Motorists are being warned that gusts of 80mph are likely to hit North Yorkshire with 65mph blasts due in North-East England and the Borders.
The Met Office has issued amber warnings for Scotland, Northern Ireland, and North-East and North-West England. These mean that drivers should "be prepared".
The Met Office has also issued yellow alerts - meaning "be aware" - across many parts of Britain, warning them of potential ice, snow and rain.
Forecasters are tellin g drivers to brace themselves for testing conditions and travel disruption with bridge closures and ferry service cancellations possible.
They predict 80mph gusts to hit exposed coastal routes and over the hills and between 60 and 70mph in several other parts.
The RAC has plenty of advice for driving in high winds , such as gripping the wheel firmly and not parking under trees.
Drivers en route from Fort William to Inverness were also hit by a 150-mile diversion following a landslip on to the L e tter Finlay stretch of the A82 Spean Bridge to Invergarry road.
South Uist has borne the brunt of the fiercest winds with 91mph reported. Mainland Scotland's Aberdeenshire town of Inverbervie and Forth Road Bridge have suffered blasts of 69mph.
