Western Cape transport MEC Robin Carlisle says lowering the blood alcohol limit for drivers will lead to fewer prosecutions, it was reported on Tuesday.
"What that means is when you bring the limit down so much, other factors can play a role, so the smaller you make the interval, the higher the chance that other factors can play a role," he told the Cape Times.
This could lead to fewer prosecutions as test results might have "unintended consequences".
He did also not support the proposed amendment to the National Road Traffic Amendment Bill because there was no scientific evidence a further reduction in the alcohol limit would lead to fewer accidents.
The national transport department was considering lowering the blood alcohol limit from 0.05g/100ml to 0.02g/100ml.
In effect, drivers would have to drink less than a can of beer, one shot of whisky or 75ml of wine.
Automobile Association spokesperson Gary Ronald told the newspaper that if the amendment was passed into law, people would be forced to change their attitude towards drinking and driving.
