A mother and daughter described their “traumatising” experience after being spun sideways in a 70mph hit-and-run on the M1.

Susan Gee, 53, was driving with her daughter, Jessica Gee, 28, back from shopping at atria Watford when their car was hit.

The pair said they could barely follow what happened in the chaos, but between dashcam footage from other drivers and what they could remember Jessica explained what happened.

She said: “We were probably doing 70 and out of nowhere a black Range Rover spun out of control and hit my mum’s car at about 90 degrees.

“But the impact spun them back into the right direction and they sped off at the speed of light.

“We managed to swerve the central reservation. If we had hit that we would be dead.

“We are just traumatised. We are going to be seeing the doctors now and I think we’ve probably got PTSD. We are not in a good way, either of us.”

Two passing motorists courageously pulled up to help, one parking in the hard shoulder and one behind Susan’s vehicle. They then walked on the motorway to get the cars onto the hard shoulder.

Hertfordshire Constabulary confirmed that they were called at 1pm on December 31 to reports of a crash on the M1 northbound, just before junction 6.

A spokesperson said: “Two vehicles were involved. One of the vehicles failed to stop at the scene.

After the crash, which occurred around 12.40pm, Jessica put out an appeal on social media to find the witnesses who helped them and help locate the driver who failed to stop.

She added that dealing with insurance is set to be “really hard” if the driver is not found,  but also praised police for being proactive and communicative.
