Sefton Central Labour MP Bill Esterson said the motorist in Sefton was being priced off the road and called on the Tory-Lib Dem government to slash VAT on petrol.
Bill said the soaring price of petrol was forcing ordinary motorists here in Sefton off the road and driving businesses to the wall.
Figures released this week suggest that motorists in Sefton are paying £324.79 in "excessive motoring taxes".
The Labour MP said the Tory-Lib Dem government needs to take decisive action to help the motorist.
Bill said: "The price of petrol is way too high and is hitting the ordinary motorist hard. High fuel prices are hitting families and businesses hard at a time when the UK economy has flatlined for twelve months.
"Some reports suggest that low-paid workers are paying a tenth of their income just to fill up a family car.
"Both the Labour Party and I have put the case in Parliament for the VAT on petrol to be slashed to take the burden off the ordinary motorist.
"We need to give some relief to the motorist and the many businesses which are going to the wall because of the soaring price of petrol.
"While the wholesale price of oil is out of the hands of the government, they can make life easier for all of us at the pump. Dropping VAT is the best way to do that.
"At a time when the price of living is rocketing, which is also affected by the price of petrol, a cut in VAT on fuel would make a huge difference."
While petrol prices soar and motorists find it hard to pay the extra costs, Bill backed St Helens North Labour MP Dave Watts' call for the Tory-Lib Dem government to reverse last January's VAT hike.
Bill said: "Motorists are paying a high price to stay on the roads, this government must now reconsider the effect its increased taxes on fuel will have on the economy and examine ways of working with industry to ensure that falls in oil prices are passed on to consumers.
"I am backing Dave Watts MP's call for the government to act immediately to cut the cost of fuel and get the economy moving again, for instance by reversing January’s VAT rise which would cut 3p off a litre of petrol.
"This Tory-Lib Dem government is making life very difficult for everyone here in Sefton Central. Their policies are hitting the motorist hard and they are stifling any chance we have for growth in the economy.
"The government should act now to ease the squeeze on families, support businesses and get the economy moving again"
