Johannesburg - The taxi strike that left commuters stranded in Johannesburg was expected to also disrupt matric pupils writing exams on Monday, the Gauteng education department said.
"We have been told of a possible one-day strike that has already affected Soweto. We appeal to operators to consider learners writing exams," spokesperson Phumla Sekhonyane said.
"We appeal to parents to make alternative arrangements and if they can't, to contact schools if their children are affected."
She said 1 000 students are expected to write agricultural science on Monday morning and 25 000 students are expected to write history in the afternoon.
She said schools would make provision for pupils that have been affected and are late.
Earlier, the Johannesburg metro police said the strike was expected to also disrupt the Reya Vaya bus service.
"All we heard is that the Reya Vaya routes in Soweto, Auckland Park and the CBD will be affected," spokesman Chief Superintendent Wayne Minnaar said.
It was not immediately clear what triggered the strike.
Minnaar said the affected routes would be Chris Hani road, Mooki, New Canada, Kinsgway in Auckland Park, Empire road and the inner city.
He said motorists from Soweto should use Elias Motsoaledi and Main Reef roads as alternatives.
The SA National Taxi Council said it did not call for the strike.
"We do not know about the strike, if we called for a strike we could have informed commuters," said president Philip Taaibosch.
Minnaar said traffic flow in the inner city was expected to be disrupted from 10am to 1pm.
