Usually no, electric scooters cannot get up to highway speeds, however you may be able to find some that do if you look in the right places or right websites.
scooters in New jersey are illegal unless you have a lisence, so riding at night is a bad idea.
the above was another members answer however it is wrong ......
Federal law allows electric scooters...
Depends on how powerful the motor is. Rather slow/weak electric scooters can be driven any old how, but if it's powerful/fast enough a license (or at least the appropriate age) can be required.
Depending on how strong your scooter is, you may legally ride on the highway. You should get a 250 cc scooter, which is strong enough to keep up with the traffic.
