There’s at least one thing that both sides of the city’s congestion-pricing debate agree on: You can’t trust the MTA.

Groups for and against the plan to fund needed subway repairs by tolling drivers below 60th Street in Manhattan clashed over its specifics during a Manhattan rally Sunday — but they both added that either way, the MTA’s involvement guarantees problems.

“There is a level of distrust in eastern Queens and other parts of New York City about the MTA that is on an Olympic level,’’ said Queens Councilman Barry Grodenchik, who was at the press conference at Tramway Plaza, in the shadow of the Queensborough Bridge, to protest the toll plan.

His Bellerose district has no subway or Long Island Rail Road stations, and his constituents include drivers for hire who would be slammed by the tolls.

“They don’t seem to be able to deliver,” Grodenchik said of the MTA. “They don’t seem to want to expand services.”

State Assemblyman David Weprin and state Sen. Leroy Comrie also attended the event, rounding out about a dozen anti-congestion-pricing advocates slamming the state panel’s plan released Friday.

But they struggled to be heard over the shouts of about 20 congestion-pricing supporters, who demanded the city’s drivers make sacrifices.

Still, Brooklyn Councilman Brad Lander, who opposes the nay-sayers, conceded, “My constituents don’t trust the MTA, either.”

But he argued that New Yorkers “have no choice” but to hope the plan is enacted and the MTA doesn’t waste the money.

“We can’t say, ‘Well, we don’t trust the MTA, so therefore we’re not willing to come up with the revenue that’s needed to fix the subway,’ ” he said. “We’ll wind up worse and worse and worse.”

The state’s Fix NYC panel Friday released its recommendations for lessening traffic in the city by enacting the tolls and raising up to $1 billion to fix the crumbling public transit system.

The plan calls for up to $12 fees for driving in Manhattan below 60th Street that could be imposed starting in 2020, while avoiding unpopular proposals to toll the East River bridges.

For-hire vehicles including app-based services such as Uber would also have to pay a surcharge — a proposal that got mixed reviews from Queens pols whose borough is home to the city’s largest share of cabbies.

Weprin said he didn’t mind the surcharge on the app-driven taxi services.

“Certainly at this point, green cabs and yellow cabs are at a competitive disadvantage with these app services. So I think to make it a little more equal and to also bring in revenue, I think the concentration should be on the app-based services,” Weprin said.

The Fix NYC panel is also recommending that cops better enforce rules already on the books — such as those banning drivers from blocking intersections in bus-only lanes — and suggesting City Hall roll back the number of city-issued parking placards that allow drivers to defy parking regulations with impunity.
