A similar surcharge was implemented in the fall of 2008, when gas prices rose to about $4 a gallon. That surcharge lasted three months.
The average price of a gallon of gas in Washington Monday was $3.77, 19 cents higher than the national average of $3.58. Last month, the average D.C. gas price was $3.41.
Chicago approved a similar $1 surcharge on taxi rides in January, and other cities are considering following suit.
