Research is being conducted into the possibility of reducing the legal speed limit to 100 kilomeres per hour, Transport Minister S'bu Ndebele said on Monday.
He said reducing the limit and banning alcohol before driving were some of the ideas that could reduce the country's death toll.
The current festive season death toll stands at 1475.
Ndebele said that while there had been an outcry on reducing the speed limit, the idea should not be dismissed outright.
"Let us have this debate about reduction of speed, from 120km/h to 100km/h."
The minister claims high speeds were a major factor in 1200 crashes during the festive season.
"Speed and drunk driving kills," he said.
Of the approximately 13 000 motorists arrested during the festive season, 314 were charged for speeding.
About 2400 people were arrested for drunk driving.
On average, at least 40 people are killed on the country's road every day and over 1000 die every month.
