"Issuing of AARTO 01, 02 an 03 infringement notices (fines).
There are only a few ways in which an infringement notice may be issued to you.
By a traffic officer at the site of the alleged infringement. (AARTO 01 or 02)
By a traffic authority who has captured an alleged infringement electronically - i.e. by camera (AARTO 03) within 40 days of the alleged infringement and serving it on you via registered mail or personally at your registered address on eNaTIS. There is NO PROVISION for personal service of AARTO 03 infringement notices at the roadside.
By a traffic authority issuing you with an infringement notice sometime after you have been issued with an AARTO 31 (unattended vehicle) notification. (AARTO 03) within 40 days of the alleged infringement and serving it on you via registered mail or by personal service at your registered address. To reiterate, there is NO PROVISION for personal service of AARTO 03 infringement notices at the roadside, including but not limited to doing so at roadblocks.
Note: In the case of a traffic officer issuing you with an infringement notice, the AARTO lifecycle comes into play immediately when the infringement notice is issued.
Note: In the case of an infringement notice that is issued after the fact, the traffic authority may issue the infringement notice up to 40 days after the alleged infringement occurred. If they take longer than 40 days to issue the infringement notice, then it is invalid and unlawful. The lifecycle of the AARTO process then comes into effect from the day on which it is delivered to the accused by registered mail, or 10 days after posting via registered mail."
