"The tolls - designed to help reduce traffic, noise and pollution - were approved by Stockholm voters in a September referendum. However, the proposal met strong resistance from commuters living in suburbs outside city limits."
Depending upon the time, drivers will pay $1.50 to $2.90 to enter the city.
"The government said the system would be similar to the one introduced on a trial basis between January and July last year. One difference is that charges would be tax-deductible for companies. Public buses and vehicles with disabled tags would be exempt."
"Studies last year showed that weekday traffic dropped by an average of 20 percent during the trial, while pollution decreased 9-14 percent."
"The money raised from the tolls would be used to improve the city's road network."
