A motorcyclist caught driving with a suspended license at the Bronx-side entrance to the Throgs Neck Bridge decided to jump rather than face arrest yesterday. Rocky Sanchez, 43, has had his license suspended 17 times, and when MTA Bridges and Tunnels Officer Charles Luce pulled him over by the toll plaza, Sanchez wasn't about to go down without a fight. First he sped away from Luce, then abandoned his motorcycle, ran across six lanes of traffic, climbed over the wall and jumped about 30 feet!
