Let's look at the relevant legislation. In terms of section 27(5) of the National Roads Agency Limited and National Roads Act 7 of 1998: "Any person liable for toll who, at a toll plaza or other place for the payment of toll determined and made known in terms of subsection (1), refuses or fails to pay the amount of toll that is due—
(a) is guilty of an offence and punishable on conviction with imprisonment for a period not longer than six months or a fine, or with both the term of imprisonment and the fine; and
(b) is liable, in addition, to pay to the Agency a civil fine of R1 000. This amount may be increased in 1999 and annually thereafter in accordance with the increase in the official consumer price index for the relevant year as published in the Gazette."
So the article is correct.
