I hear your opinion on this debate ICM, but here is my opinion;
Firstly its not law to get tagged, so I won't.
Secondly, Sanral MUST bill me in accordance with the law. Basically they have 32 days to do so, after the expiry of the 7 day period of grace.
Thirdly, I am hoping that the opposition to e-toll (OUTA, FF+, etc) will win their court case, and e-tolls will be binned.
I will pay, when Sanral complies with the Act, and bills me accordingly. AND PROVES that it was my vehicle at EACH and EVERY gantry they bill me for.
Simple.
I'm not breaking any laws, in fact I'm insisting that Sanral complies... 
absolutely right and well within your rights to do so.
where does this 32 day period come from and where does it state you are excused if not received, where is this formulated?
Edit: if you are referring to the below be well aware of the fact that if the letter does not get to you within 39 days, it does not mean you are excused. The act is also silent on a number of issues , I look forward to them being tested
In terms of regulation 6(5) of the e-Road regulations "If an alternate user does not pay the toll contemplated in terms of sub-regulation (4) within the time and at the place and subject to the conditions that the Agency may make known and determine, the Agency must within 32 days after the alternate user has used an e-road but after expiry of the grace period and unless the user has registered, send an invoice to the said user, to the last known address provided in terms of the National Road Traffic Act by such user, reflecting the amount of the toll payable and such invoice shall be paid by the said user on or before the date reflected on the invoice."
I think its quite clear ICM.
They have to bill me within 39 days, its in their act.
So IF I get an invoice, AND the date on the invoice is NOT within the 39 days stiplated in THEIR act, I will return said invoice to them, with a copy of the relevant act, and tell them to take me to court.
Maybe I will be the first one, and it can set a precedent? If not, the first person to test this act will set the precedent, and then they will have to make sure that they comply by sending out their invoices witin the specified time-frame.
Maybe I'm just a hopeless optimist, but I believe in the Law... 
Oh, and according to my calculations, they only have 4 more days to issue my first invoice, I used the e-toll road on the day they opened 
No its not clear ....the act merely says they have to invoice you within that period of time not the fact that you must receive the invoice. I suspect even failing to actually receive the invoice the debt will only prescribe in due course (3 years) The fact that the post office has a go slow or dumps the mail does not excuse you of the debt. guys, don't rely on this 39 day period as a way to get out of the debt. Please don't.
another lil issue you okes must not forget is that it is clearly marked that you must pay tolls, u cannot claim ignorance of this down the line. So if you use the road you know there is an obligation pay.
in closing on this, SANRAL is under no obligation to ensure you receive the invoice within 39 days ...merely the fact that they must issue an invoice within the period...if you only get it a year down the line you will be liable. simple
Edit: Meant to add, in terms of section 6(6) if a user fails to pay SANRAL can follow criminal and civil processes to get payment. Now this has obviously yet to be tested but if SANRAL are sucesful in this you will be liable for the initial payment and a hefty chunk of legal fees .......
Now OUTA have run out of funds taking this to the courts and they been sponsored by society at large.....can you as an individual afford this if you lose...and even if you win its going to cost you a lot...
Just on the photogrpahs mentioned in a previous post, an invoice does NOT have to have a photograph of every gantry passed..... you are of course entitled to go to a SANRAL office an request all of this....from what I can make it this does NOT delay the process of payment.
look, there is a lot of stuff that has yet to be tested and ironed out ...... but thus far SANRAL have had the upper hand, I suspect this is going to be maintained due to pressure from the govrnement etc.
