What information can the public pass to VOSA?
Commercial vehicles operating illegally
The Vehicle and Operator Services Agency (VOSA) works with the public to collate information on Heavy Goods Vehicle (HGV) and Public Service Vehicle (PSV) operators, to ensure we target those who are non-compliant rather than burdening those who work within road safety and environmental guidelines. VOSA’s intelligence officers will follow up reports on operators disabling tachographs or speedlimiters, running on red deisel, operating against licence requirements and also running vehicles which are affecting environmental standards. The public can help to reduce vehicle emissions by reporting lorries and buses which are extremely smoky. VOSA will contact the vehicle operator and investigate the report.If you have queries regarding a company requesting for an Operating Licence, please read Raising an Objection against an Operator for further information.
