Extendable towing mirrors modification Part 1 | Trim down at home DIY

[@MichaelDunbar-f3n]

By trimming them down is it still ADR compliant by modifying them ?

I'm no expert, so this isn't gospel. But I have had experience of being defected many times, and i also used to work in a job where I had to get cars roadworthy inspected. Anything that puts a vehicle outside factory spec is technically a breach of ADR, unless the accessory is ADR approved for that vehicle. These are cheap towing mirrors that probably not ADR approved anyway (afaik). You'd be very unlucky to be defected for this
