Conditions on your heavy vehicle licence
You can have conditions added to your heavy vehicle class licence.
Glasses or lenses required to drive (XR)
You must wear corrective lenses at all times while driving a commercial vehicle or a vehicle greater than eight tonnes. This is applied when you need corrective lenses to pass the eye test to commercial vehicle driver standards.
Must drive automatic heavy vehicles only (XU)
