Here's one Northampton mum that does NOT always know best

Gobsmacked traffic police caught and mum and son desperately swapping seats after spotting a car going through a red light in Northampton yesterday.

And another father trying to be an 'amber gambler' was found to have his five-year-old daughter sat in his car — while her car seat was in the BOOT!

Officers from the county's Safer Roads Team pulled the vehicle over to 'have a word' found a woman midway through climbing into the driver's seat with a male 'passenger' in the back.

PC Dave Lee revealed: "The son had climbed into the back and mum was mid-way through climbing into the driver's seat as we opened the car door.

"Turned out the son had climbed into the back seat after mum told him to.

"He only has a provisional licence but it was mum's car and the son wasn’t insured so both were reported for driving offences.

"Sometimes it’s best NOT to do what your mum tells you to!

"A second car was stopped after the driver went through a red light in front of us travelling at speed.

"In the back was his five-year-old daughter not in a child seat. He thought it was OK, though, as he was nearly home and the child seat was in the boot.

"The driver has been reported and a referral made to child protection."

Meanwhile, a van driver on the A14 paid the price for being an easy ticket after being spotted speeding and not wearing a seatbelt.

Officers later found the driver was not insured and so seized the vehicle.

Speeding and not wearing a seatbelt are two of the 'fatal four' offences Northamptonshire Police are targeting during a three-month road safety campaign.

Operation Journey was launched last month to crack down on unsafe drivers and vehicles.

The 'fatal four' — which also includes using a mobile phone behind the wheel and drink-driving — is the biggest contributor to deaths and serious injuries on the county's road.
