Argentine Transport Minister Mario Meoni died late on Friday in a traffic accident about 110 km west of Buenos Aires.
The accident occurred when Meoni was driving alone during a storm to Junin, his home city.
"With his death, Argentina loses a thorough, tireless and honest politician and an exemplary official," President Alberto Fernández said in a statement.
Meoni, 56, was married with two children. He had been transport minister since December 2019, when Fernandez assumed the presidency.
