Police have asked for lower traffic restrictions in the west of Scotland after heavy rain in the area.
The restrictions will be active across the whole motorway network due to a series of flash floods.
The Glasgow subway has also been suspended as a result of flooding caused by the torrential downpour.
A warning has been issued to drivers in Glasgow and South Lanarkshire with surface water affecting conditions.
Traffic Scotland issued the warning on Thursday after flooding caused the closure of one lane of the M8 motorway between junctions 18 and 19.
Motorists have also been advised to drive to the conditions and switch their lights on.
Road Police Scotland Tweeted: “It’s horrendous weather in the west of Scotland. We’re liaising with Traffic Scotland and asking for lower speed restrictions across the whole motorway network as there’s lots of flash floods.
“Please, please drive to the conditions and switch your lights on.”
ScotRail also warned of disruption to their services and advised users to check their journeys before heading to the station.
The train operator said heavy rain has flooded the line at Bridgeton Station in Glasgow’s east end, causing signalling problems and blocking the line.
Services running through the station are being suspended and disruption is expected to last until 8pm.
Flooding also caused signalling problems at the nearby Bellgrove Station, Network Rail Scotland said.
The organisation tweeted: “We’re responding to a signalling problem caused by flooding near Bellgrove station, trains are unable to run due to this.”
Floodwater closed some roads in the east end of Glasgow with drivers advised to follow police direction.
Glasgow City’s Council’s traffic management service said London Road was closed between Mauchinfauld Road and Braidfauld Street “until the flooding is cleared”.
The service also warned of “heavy flooding” at the junction of Paisley Road West and Berryknowes Road in the south side of Glasgow.
Elsewhere, Traffic Scotland said the A77 near the A751, Cairnryan, Dumfries and Galloway, was restricted in both directions due to surface water affecting the carriageway.
