Speed does kill. In fact, for every mile per hour increase we might expect the accident rate to rise by over 3% (see TRL report 421).
Therefore it is not only excessive speed (over the legal limit) but inappropriate speed (too fast for the road conditions) that has an effect on the accident rate.
I suggest that to tackle inappropriate speed this country needs lower speed limits and increased speed enforcement - whether it be by physical 'traffic-calming' measures or by cameras, hidden or not.
Our police officers cannot be expected to take all the responsibility for speed enforcement. I would rather see them investigating armed robberies, rapes and murders.
