A motorcyclist busted for blowing through George Washington Bridge toll gates allegedly hid that he had open warrants against him — by posing as his own brother.

Richard Boyce, 44, owed $7,500 in unpaid tolls and had several warrants when he was pulled over by Port Authority police officers on June 15, police said.

But the Deepwater, NJ, resident gave cops a license bearing his brother’s name and got away with minor charges, police said.

On Wednesday, he was taken into custody in Belmar on unrelated traffic charges, ­police said.

This time, he gave his real ID, allowing PAPD cops to track him down.
