Lockdown speeding has become an unwelcome by-product of the Government’s fight against coronavirus with 20 police forces catching their worst offenders at speeds in excess of 100mph, according to data analysed by the RAC as part of a freedom of information (FOI) request to all British police forces.

The worst speeder in the first three weeks of the lockdown was caught in West Yorkshire driving at 151mph on the M62 motorway – a shocking 81mph over the speed limit. This was 11mph faster than the next fastest recorded which was 140mph on the A14 in Suffolk.

Five forces – Northamptonshire, Gwent, Staffordshire, Kent and Humberside – all caught motorists driving at speeds in excess of 130mph on the motorway and three others – Police Scotland, The Met and Lancashire – recorded drivers at speeds over 120mph.

The highest speed seen in Derbyshire Constabulary’s area, however, was particularly worrying as it was 108mph captured in a 40mph limit on the M1 – a frightening 68mph above the speed limit. The only other force whose highest speed was in a 40mph limit was Bedfordshire – here the driver was clocked at 104mph on Airport Way in Luton.

Only three forces saw their worst speeding offences occur in 50mph limits, with South Wales Police recording by far the worst with a driver being caught at 108mph on the M4 at Port Talbot. Four constabularies captured their worst speeding offences in 60mph limits with a driver in West Mercia snapped at 92mph on the M5 between junctions five and six.

RAC road safety spokesman Simon Williams said: “Some of the speeds police forces have caught drivers doing are shocking. At such high speeds there is virtually no time to react should anything unexpected happen in front such as a car changing lanes at the last second or a vehicle having to brake suddenly.

“While the most of highest speeds were recorded were on motorways, some occurred on roads with much lower speed limits, which is an even greater concern. The figures for speeding offences on 30mph roads are particularly worrying as far more people have been walking and cycling due to the lockdown.”
