(19,429 posts)The NJ Turnpike reads the tag at on and off ramps, as does the PA Turnpike.
There are NYC bridges that are 35 mph in the high-speed lanes and 5 mph in the toll booths.
Practically speaking, drivers on the GSP don't slow much for the high-speed lanes, and many go through the old toll boths at 20-25 mph.
EZPass works from Maine to Virginia and west to Illinois.
California is always different, but in the future with $10 gas not many people will be driving between the east and west coasts.
If for example, NY Thruway can't read your tag, they use your license plate to contact NJ EZPass. If your license is in the NJ database, they ding your EZPass account and pay NY Thruway. This could be used between EZPass and other states with incompatible responders.
