Government should reconsider the road freight system in the wake of Public Service and Administration Minister Collins Chabane's death, Cope said on Tuesday.
"[The] Congress of the People is aware of serious discussions in government about suitable modes of transport for goods," spokesman Dennis Bloem said in a statement.
At present, the freight system was heavily skewed in favour of road transport, with large trucks creating an unavoidable hazard.
"Reverting extensively to rail for transportation of goods will save our roads which have to undergo frequent and costly rehabilitation caused by heavy vehicles."
Chabane and two bodyguards -- Sergeant Lesiba Sekele and Sergeant Lawrence Lentsoane -- were killed when a truck allegedly made a U-turn in front of their car on the N1 near Polokwane, Limpopo, in the early hours of Sunday morning.
The truck driver was expected to appear in the Polokwane Magistrate's Court later on Tuesday.
Cope also wanted increased policing on the roads.
"The Easter long weekend is the time to show a new determination by government to curb traffic violations," Bloem said.
"We cannot afford to lose another life, least of all of a man of the calibre and quality of Collins Chabane."
