Transportation officials say the state won't begin its new truck tolls until at least the end of May, a delay that's expected to cost the state an estimated $20 million in lost revenue.Transportation Director Peter Alviti Jr. told lawmakers last week the department is still testing tolls. He says the governor wants to be absolutely sure they're functioning correctly before they go online.

Officials had initially said they planned to begin tolling large commercial trucks by December, and then pushed that back to March.
