Fleet cars are invariably 'cleanest' because they are the newest. RAC campaigns manager Edmund King said: 'We emission tested more than 100,000 vehicles and 10% cause 50% of the pollution. Fleet cars are in the best 25% because they are regularly serviced.'
A local authority 'smoke police' scheme involving on-the-spot fines for motorists driving polluting vehicles will be trialled in six cities shortly. The AA. wants a fairer fining system if cars fail the exhaust test, with environmental policy head Martin Maeso saying: 'The government insists the scheme is to be self-financing, which will encourage councils to fine every driver. Conscientious drivers should be given a short period of grace to allow them to fix the problem.'
