More than 160 Metrobuses are back on the road Monday after an engine issue sidelined about 10 percent of Metro's fleet.
Two of Metro's buses suddenly stalled last month, prompting the transit agency to take 164 buses out of service for a safety inspection.
The two buses were going less than 10 miles per hour when the engines cut off with no apparent warning, Metro said. Two people had minor injuries after the incidents.
The 164 buses, which were manufactured by New Flyer in 2015 and 2016, were pulled from service and had to undergo safety checks.
During that time, Metro adjusted the engine speed on some of the buses and completed a number of test runs.
To help cover the shortage, Metro deployed a fleet of about 80 reserve buses to help offset the decrease in buses. Some commuters had to deal with longer wait times between buses.
