New Jersey starts odd-even gas rationing in 12 counties at noon on Saturday.
From The Star-Ledger:
[R]ationing will take place in Bergen, Essex, Hudson, Hunterdon, Middlesex, Morris, Monmouth, Passaic, Somerset, Sussex, Union and Warren counties.
According to the order, all retail gasoline dealers are required to sell fuel for use in a passenger vehicle according to the last number appearing on a vehicle's license plate.
Vehicles with license plates, the last number of which is an odd number, can fill up at stations in these counties only on odd-numbered days of the month, the order said.
Vehicles with license plates, the last number of which is an even number, can fill up only on even-numbered days.
Zero is considered an even number.
The order does not apply to the purchase of fuel by individuals with gas canisters. Walk-ups are still permitted.
All license plates not displaying a number, such as vanity plates, are considered odd, and should fill up on odd numbered days of the month, the order said.
