Sir – I welcome the news that speed cameras in Oxfordshire are to be turned on again.

Liberal Democrats at the County Council opposed their switch-off in the first instance, and we’re delighted that a deal is being brokered to ensure that this bad decision can be reversed.

Hopefully, their return will help prevent accidents. We know that speed is only one factor in accidents, but the very presence of speed cameras act as a useful reminder and deterrent for when car drivers forget to monitor their own speed. It does seem that speeds have increased since the switch-off — we very much hope that this is not reflected in the casualty figures at the end of the year.
