Indian truck drivers called off their strike Friday after the government met their demands to roll back rising road tolls, ending a standoff that could have paralyzed much of the Indian economy, union leaders and government officials said. The government agreed to reverse a recent hike in toll road fees after the All India Motor Transport Congress, which represents 4.8 million truckers, went on strike Wednesday. The two sides came to an agreement before dawn Friday and union leader Gurinder Pal Singh said trucks are already back on the roads. “The demands which the truckers were asking for have been met,” Singh said.
