What's on the plate, Cuba?
Coded tags on automobiles tell authorities a lot about their drivers.

HAVANA - It's Cuba's twist on "you are what you drive." Here, you are your license plate.
A rainbow of colors and an alphabet soup of codes tell the discerning eye how important you are in the egalitarian revolution as you whiz by - your nationality, what you do for a living, and, often, how high you rank at work.
"The kind of car you drive says something," said Norberto Leon, a retiree who collects pocket change by watching parked cars. "The license plate, it says more."
Cuba's painstaking color-coding of license plates, a system copied from the former Soviet Union, is one way authorities have kept tabs on people and their vehicles for decades.
The government owns most cars. They have blue plates with letters and numbers that indicate when and where the vehicle can operate and whether the driver can use it for personal as well as professional reasons.
Inspectors wait along highways out of town and other high-traffic areas, stopping official cars to check their route sheets and to make sure they aren't being used for a jaunt to the beach.
Executives at government-run firms, who get caramel-colored plates, have more leeway. But even they may only be allowed to use their cars to get to and from work.
"It's a form of control," said Weichel Guera, a National Office of Statistics chauffeur who is assigned a government sedan that he can use only to ferry top officials during business hours. He and his Lada spend most of their time parked outside the statistics building.
In the Soviet Union, Cuba's benefactor in many regards, all plates were black and white, and the first two letters specified the province where the vehicle was registered. The third letter denoted state or private ownership. The Soviets also assigned numbers for embassy license plates based on a country's recognition of the Bolshevik Revolution: Plates for Britain, the first to accept the czar's ouster, are still 001.
In Cuba, the first letter in the license indicates which of 14 provinces the car is from, such as H for Havana.
Military vehicles have mint green, rear-only plates; olive-green plates are for vehicles issued by the Interior Ministry, including Fidel Castro's fleet of armored Mercedes 280s, built between 1982 and 1984.
Black plates are for foreign diplomats, who don't have to adhere to traffic laws. White-plated vehicles of Cuban government ministers or heads of state organizations also drive as if they have diplomatic immunity, though technically they do not.
The last three digits on diplomatic plates often denote the professional rank of the driver. A Mercedes with black license plate 179-004 means the fourth most-important officer from the Russian Embassy uses the car.
"Everyone's supposed to be equal under socialism, but when a late-model sedan with black license plates roars down Quinta Avenida in Havana, the driver is saying, 'Look out, I'm a big shot,' " said Tracey Eaton, a U.S. journalist.
For years, officials' cars were Iron Curtain imports. Now many official sedans are imported from China or bought from Havana's Peugeot, Fiat, and Mercedes dealerships.
Rental cars get maroon plates. Foreign journalists, religious leaders, and Cubans working for overseas firms have neon-orange ones. Red "provisional" plates allow vehicles to circulate while officials sort out just what color tag they should get.
Most of the half-century-old American vehicles that create a moving museum along the island's potholed streets have yellow license plates, meaning they are owned by ordinary Cubans.
The holdovers from Detroit's chrome-and-tailfin era are still prominent on the roads because Cubans with non-VIP jobs can buy and sell only cars manufactured before the Castros took power in 1959. Buying newer vehicles requires government permission, including justifying how you can afford a car when the communist state controls well over 90 percent of the economy and pays employees an average of about $20 a month.
"It's normal," said Leonardo Rodriguez, whose 1957 Buick Special has yellow plates. "Maybe it's confusing for a foreigner, but for us it's not."
