TRENTON, N.J. » Motorists in 12 northern New Jersey counties will be allowed to buy gasoline just every other day under an order by Gov. Chris Christie that takes effect at noon today.

Christie says he made the order late Friday to prevent a fuel shortage in the state hard-hit by Superstorm Sandy. He says he wants to ease the problem of extended wait times and long lines at gas stations.

Many gas stations were forced to close because of a lack of electricity or gasoline, causing those still open to be overburdened with scores of additional customers.

Drivers with license plates ending in an even number will be able to buy gas on even-numbered days, and those with plates ending in an odd number can make gas purchases on odd-numbered days.
