the tolls on the NJ Turnpike depend on what you are driving and where you get on and off of the Turnpike and whether or not you have ezpass.
There is a calculator here at http://www.state.nj.us/turnpike/nj-vcenter-tollrates.htm?tollrates=1&Submit2.x=36&Submit2.y=13&Submit2=Start+Calculator
There is also a printable NJ Turnpike Toll Rate Schedule here at http://www.state.nj.us/turnpike/nj-vcenter-tollmap.htm
For instance the car tolls on the turnpike for going from exit 8 to 7a would be .60 cents. Of course if you have ezpass it might be a different toll.
