However, with good behaviour he could be released in six years. The charges were read out to him in Zulu and through an interpreter he told Judge Kate Pillay: "I admit all the charges." May pleaded guilty to 24 counts of culpable homicide, two charges of fraud, one charge of entering South Africa illegally, two charges of being in possession of fake driver's licences, one charge of operating a vehicle without a valid professional driving permit, and one charge of failing to comply with a road traffic sign.
'I admit all the charges'
On the evening of September 5 last year, in rush-hour traffic, May's truck smashed into four minibus taxis and two cars at an intersection at the bottom of Fields Hill in Pinetown.
Twenty-two people died at the scene. Two died later in hospital.
May has been in custody ever since. He was previously denied bail by the Pinetown Magistrate's Court.
Initially, he was charged with 24 counts of murder, but this was changed to 24 culpable homicide charges.
He was sentenced to 15 years' imprisonment for each of the culpable homicide convictions, with five years suspended.
He was also sentenced to one year for violating the immigration laws and four years for each of the traffic and licence violations.
All the sentences are to run concurrently and the 14 months May has been in custody were taken into account.
"The effective sentence is one of eight years and 10 months. With good behaviour that could be reduced by a third or more," said Pillay.
She said she believed May was remorseful and had "demonstrated contrition for his actions".
May's efforts to secure employment without a valid licence had "set a chain of events in motion that were tragic" despite his "noble intentions" to support his younger brother in Swaziland.
"The accused too did not emerge unscathed. He has had to sit in jail more than a year awaiting his fate."
Pillay said the court took notice of the fact that drivers used Fields Hill to avoid paying toll fees.
The accident highlighted the need for truck owners to verify the details and licences presented to them by prospective employees.
She urged traffic authorities to step up their policing on Fields Hill.
In his plea agreement, read into the record by his advocate Louis Barnard, May admitted he knew his driving permits were not legitimate and he had misrepresented to his employer Sagekal Logistics that they were valid.
It also emerged from the agreement that May had failed an initial driving test with the company two weeks prior to his employment on September 2, 2013.
The fateful trip during which he lost control of his vehicle down Fields Hill was his first for the company.
He had taken a load up to Johannesburg and it was on his return trip to Durban that he lost control of the truck.
May kept his head down when press photographers tried to take pictures of him before he entered the dock.
On entering the dock a small group of supporters waved to him.
As he left the dock after being sentenced a woman shouted from the public gallery: "We love you Sanele."
