(Adds SATAWU, details)
CAPE TOWN, Oct 12 (Reuters) - A deal to end a three-week truck driver strike in South Africa, which has hit deliveries of fuel, cash and consumer goods, is imminent, the Road Freight Employers Association said on Friday.
More than 20,000 truck drivers have taken to the streets in often violent protests, demanding higher wages.
"The parties have signed an undertaking that they agree to a three-year industry wage agreement which is to be signed at approximately 10 a.m. (0800 GMT) on Friday," the association said in a statement.
All four unions were part of the agreement, Magretia Brown-Engelbrecht, executive officer of the association told Reuters.
Details of the proposed deals were not yet disclosed.
The South African Transport and Allied Workers Union (SATAWU), which represents the majority of truck drivers, said it was still consulting its members on the proposal and would communicate its decision at the meeting with employers.
Petrol stations have been experiencing delays of up to a day in getting fuel and some have run completely dry, the South African Petroleum Industry Association said on Thursday.
Affected companies include logistics groups Imperial Holding , Super Group , Grindrod , Barloworld
and Bidvest .
Since August, almost 100,000 workers across South Africa, including 75,000 in the mining sector, have downed tools in often illegal and violent strikes that may hit economic growth this year and undermine investor confidence in the minerals hub.
