Rhoddodd cyfnod clo Covid-19 stop ar brofion gyrru HGV, gyda 30,000 o ymgeiswyr yn ôl y sôn yn aros am brawf.  Bydd angen amser i'w clirio. Ym mis Ebrill, gwelwyd newid y rheolau a nifer o gludwyr hunangyflogedig yn gorfod newid i statws cyflogedig. Mae'n ymddangos bod hyn wedi rhoi straen ychwanegol ar gyllidebau cwmnïau cludo nwyddau, gan arwain at gynyddu prisiau cludo nwyddau ar lwybrau allweddol.
The Covid-19 lockdown also put HGV driving tests on hold, creating a backlog reported at 30,000 applicants which will take some time to clear. In April, tax rules changed meaning a number of self-employed hauliers were switched to employed status and this would appear to have put additional strain on haulage company budgets, leading to higher haulage prices on key routes.
