A man in his 80s who failed an eyesight test after being spotted driving "erratically" on the M2 has had his licence revoked.

Sergeant Chris Wade was on patrol on the M2 in Gillingham when he became concerned by the elderly motorist's driving.

He stopped the vehicle and asked the driver to read a number plate 20 metres away.

But the motorist was unable to do so and as a result his licence was revoked by the DVLA the following day.

In 2013 new rules came into force which allow police officers to revoke motorists’ driving licences if they fail a roadside eyesight test within an hour.

Sergeant Wade said: "The onus is on the driver to ensure their eyesight does not impair their ability to drive safely.

"It is important that motorists have regular eye tests and wear glasses that are prescribed for them when they get behind the wheel.

"Those who fail to do this risk disqualification from driving and a fine of £1000."
