Community safety officials were speaking to drivers at the Orange Farm taxi rank south of Johannesburg.
"Taxi drivers who do not obey the rules of the road will be arrested. Law enforcement is non-negotiable," spokesperson Thapelo Moiloa said.
The department received many complaints from community members about taxi drivers speeding and not adhering to traffic rules.
"Residents complain about taxi drivers in the Orange Farm area, that they stop as they like and do not apply basic road safety rules," Moiloa said.
