General fitness: Operators should typically have full movement of their trunk, neck, and limbs, with normal agility. Exceptions can be made for experienced operators with disabilities after proper retraining. A stable mental state is required, and dependency on alcohol or drugs is disqualifying.

Vision: Good spatial judgment is necessary, typically requiring both eyes, though monocular vision may suffice in some cases. Distance vision should meet road-driving standards, if you wear glasses, please bring an up-to-date report from your optician.

Hearing: Hearing instructions and signals is important, but deafness may not disqualify someone if assessed properly. A forced whisper test will be conducted to assess hearing. 

Epilepsy: Operators must meet the same criteria as for an ordinary driving licence, but any new seizures need medical reassessment. Flashing beacons can trigger epileptic fits.
