Band 9 model answer
As urban congestion worsens, several governments have begun levying fees on motorists who enter central districts at peak times. In my view, such charges are a largely effective remedy, although their success ultimately depends on the quality of the alternatives offered to commuters.
The principal merit of congestion pricing lies in its capacity to alter behaviour through the wallet. When entering a city centre carries a tangible cost, many drivers reconsider non-essential trips, share vehicles, or travel outside peak hours. London's scheme, for instance, reportedly cut traffic volumes significantly while generating revenue that could be reinvested in transport. By internalising the social cost of driving, the policy nudges citizens towards more rational choices without resorting to an outright ban, and the funds raised can finance cleaner alternatives that compound the benefit over time.
Nevertheless, the measure is only as effective as the infrastructure surrounding it. If buses and trains are overcrowded, unreliable, or prohibitively expensive, drivers have little realistic option but to pay and continue clogging the roads, leaving the charge as a regressive tax rather than a genuine solution. Critics also note that lower-income workers, who cannot easily relocate or alter their working hours, bear the heaviest burden, raising legitimate questions of fairness. Poorly designed schemes may simply displace congestion to the streets just beyond the charging zone, shifting the problem rather than solving it.
In conclusion, charging motorists to enter busy city centres is, on balance, an effective instrument for easing congestion, provided it is coupled with substantial investment in affordable public transport. Without such complementary measures, it risks penalising the poor while leaving traffic largely unchanged. Governments should therefore treat the fee as one component of a wider strategy rather than a standalone fix.
Examiner’s notes
- Task Response: the position is stated immediately ('largely effective, although...') and sustained throughout, with each paragraph advancing the conditional argument rather than drifting.
- Cohesion: discourse markers such as 'Nevertheless', 'By internalising' and 'on balance' link ideas logically while referencing ('such complementary measures', 'the policy') avoid repetition.
- Lexical resource: precise economic phrasing like 'internalising the social cost', 'regressive tax' and 'congestion pricing' demonstrates Band 9 topic-specific vocabulary.
