Drivers are being urged to avoid contacting the DVLA's customer services today as workers across the UK take part in industrial action.
Walkouts on Wednesday will see some Driver and Vehicle Standards Agency staff (DVSA) who are members of the Public and Commercial Services (PCS) and Prospect unions stop all work.
The DVLA has said that strikes will specifically impact their contact centre. While the DVSA deals with driving standards, including testing, strikes will also impact DVLA resources which focus on issues with licencing.
