The number of ministers provided a car and chauffeur has fallen from 78 to 13 as part of the Government's plan to cut the deficit.
During 2010-11 the cost of providing the service was £3.8 million, which included £700,000 spent before the coalition came to power.
This figure is down by almost half from the previous financial year when £6.7 million was spent on the service, according to figures from the Department for Transport.
Prime Minister David Cameron pledged to reduce the cost of the ministerial car service with non-cabinet ministers using the car pool rather than having a dedicated car and driver.
The use of the car pool service is for official business and when travelling home from work, as long as this is a 'reasonable distance of London'.
However, all government members are encouraged to use public transport where possible.
