Letters to the Editor: The 20mph Limit and the Strength of Evidence
From the Brackenford Herald, 14 March. Two readers' letters argue about a proposed 20mph limit on the High Street, which passes two schools.
Letter A, from Ray Mills, who owns a furniture shop: 'This limit is a war on motorists. Shoppers will go to the retail park instead, and my takings will be halved. Deliveries already take long enough. In my thirty years on this street I have never seen a serious accident, and in my experience drivers are careful when children are about. The council should spend the money on a crossing instead of persecuting the people who keep this town trading.'
Letter B, from the headteacher of Mill Street Primary: 'In the last three years, two children from our school have been knocked down outside our gate. The council's own survey in October recorded an average speed of 31mph at 8:40am, when 240 children are arriving. A 20mph limit is not a war on anyone; it is the minimum a parent should expect. The consultation runs until 30 April and takes five minutes online.'
1. Compare the evidence the two writers use. Which letter makes the stronger case about safety, and why?
Read the worked answer
Letter B's evidence is specific and sourced: two children knocked down in three years, and an October council survey recording an average of 31mph at 8:40am when 240 children arrive. Those claims can be checked, dated and tied to a particular place and time, which is what makes them evidence rather than assertion.
Letter A offers an anecdote ('in my thirty years I have never seen a serious accident') and a borrowed authority ('in my experience'). Both may be honest, but neither can be tested: 'never seen' tells you about the writer's observation, not about the road. Its claim that takings 'will be halved' has no figure behind it at all.
The fair qualification is that Letter B comes from a headteacher with an interest in the outcome, and interest does not invalidate checkable figures. Letter A's strongest point is not safety but trade, and it deserves an answer; on safety, B is clearly stronger.
2. Identify two language choices in Letter A that persuade rather than inform, and explain the effect on a reader.

First, 'war on motorists'. It takes a speed limit and reframes it as an attack by one group on another, so a reader who drives is invited to feel like the victim rather than a road user among pedestrians. Second, 'persecuting the people who keep this town trading' does the same job more strongly: it flatters shopkeepers as the town's real benefactors while casting the council as a persecutor.
Smaller choices reinforce it. 'Halved' sounds precise but has no survey behind it, so a number-shaped word borrows the authority of evidence. 'In my experience' invites the reader to accept thirty years of anecdote as data.
The effect on a reader skimming over breakfast is cumulative: the letter feels like plain speaking from a local businessman, and the absence of real figures goes unnoticed. Naming the technique, not just quoting it, is the point.
3. Write the first two paragraphs (about 80 to 100 words) of a reply from the council for the Herald. It must be formal, acknowledge the shopkeeper's concern, and avoid promising anything it cannot deliver.

A model opening:
'Sir,
We recognise the concern Mr Mills raises about trade on the High Street, and we have met traders individually to discuss deliveries and loading. A 20mph limit is proposed because the council's October survey recorded average speeds of 31mph at school arrival time, and because two children have been injured outside Mill Street Primary in three years.
We cannot yet say what effect a limit would have on takings, which is why the scheme is proposed as a trial with monitoring, and why traders will be consulted on delivery times before any change begins. Residents can respond until 30 April.'
The reasoning: it answers the trade point first, so it does not look evasive, then brings the safety evidence. It hedges where the evidence is thin - 'cannot yet say', 'proposed as a trial' - rather than claiming trade will be unaffected. It never mirrors 'war on motorists'; matching an insult would undo the formal register. It ends with a practical action and a date, not a slogan.
