Motorists are facing misery on the roads as train strikes forced commuters to find alternative transport.
On Tuesday morning, a crash involving a car and a motorcycle on the M8 eastbound near junction 28 left vehicles queuing for almost an hour.
Police and TRISS rushed to the scene of the incident around 7.30am, which left two lanes closed.
A Police Scotland spokesperson said: “One person was taken to the Royal Alexandra Hospital, Paisley, for treatment.
“The road was cleared by 8.20am.”
The collision also meant vehicles on the A737 eastbound were subject to delays of 30 minutes.
Meanwhile Traffic Scotland reported heavy congestion on the approach to Edinburgh, with the A720, M8, M9 and M90 at Queensferry crossing also affected.
It comes as fewer than one in five rail services were running on Tuesday as a result of UK-wide industrial action involving Network Rail signal workers.
Tens of thousands of rail workers will participate in the strike in a row over pay, which will cripple services for most of the week.
Last minute talks on Monday failed to resolve the row over pay and working conditions.
This dispute does not involve ScotRail staff, however, it does have a major knock-on effect on the train operator’s ability to provide services.
As a result, just 180 of the 1,456 trains on ScotRail’s timetable will run on Tuesday, Thursday and Saturday due to strike action.
Services will only run in the central belt between the hours of 7.30am and 6.30pm.
The recently-nationalised train operator urged customers to only travel if they really need to, and said they should consider alternative options where possible.
