Do you need Alternatively-Fuelled Vehicle training for yourself or your drivers? The organisations listed below provide specialist AFV training to van drivers under the UK law that allows Category B driving licence holders to drive an alternatively-fuelled vehicle weighing up to 4.25 tonnes. Training lasts 5 hours and follows a syllabus published by the Department of Transport. An NRI certificate confirming that they have completed the required training and are therefore legal to drive an AFV will be issued to all candidates. Check this site frequently as new AFV providers are added regularly.
