This is the horrifying moment an HGV driver tried to alert a mum to the danger she and others were in moments before she caused a fatal car crash.
The driver can be heard repeatedly sounding this horn after Ann Marie Crook, 43, narrowly missed the vehicle while she drove the wrong way down the slip road to the M57.
Moments later, she hit the Honda Jazz of Paula Kingdon, killing her.
Crook had been driving for fives miles through St Helens before she hit the retired headteacher, LiverpoolEcho reports.
Crook had hit speeds between 92mph and 94mph during sections of road that had a speed limit of 40mph.
She then crossed onto the wrong side of the road before turning onto oncoming traffic - where she passed the HGV.
Chris Hopkins, prosecuting, told Liverpool Crown Court of the detailed accounts of witnesses who saw Crook in the build-up to the crash in October 2019.
Mr Hopkins said one driver told police: "Suddenly he became aware of the defendant's car... to his disbelief she was level with him but on the other side of the crash barrier... he watched in horror as the defendant crossed the two eastbound lanes and entered the exit slip on the M57."
According to another witness, earlier on in her journey: "He could see her hands on the steering wheel while she was looking forward and appeared to be driving in a determined manner."
One of the drivers she approached on the M57 recalled: "The defendant appeared to pick a lane and stick with it. There was no braking. The defendant drove straight and with purpose."
The court heard the vehicle in front of Paula swerved to avoid Crook, leaving the much-loved former teacher no time to react.
Mr Hopkins said Crook's intentions remained unclear, but added: "All of the evidence indicates this was a deliberate act and the only sensible conclusion that can be drawn is that the defendant was trying to harm herself."
Paula and Crook both had to be cut out of their vehicles and taken to Aintree Hospital.
Crook spent time in a critical condition.
The mum-of-two told police she had no recollection of the incident and suggested she "had taken a wrong turn and panicked".
Mr Hopkins said: "The fact that that explanation is maintained by the defendant is something which has caused great distress to family members of the victim."
A letter written to Judge Garrett Byrne by Crook ended with her claiming she had "no explanation" for her actions.
Highlighting the evidence that Crook made no attempt to avoid a crash, he concluded it was not "a case of taking a wrong turn and then panicking, it was a deliberate course of conduct".
The judge added that, if it had been Crook's intention to harm herself, it was "a profoundly selfish one because you were prepared to injure or kill others" in achieving that goal.
Crook admitted one count of causing death by dangerous driving and was sentenced to four years and eight months.
She was disqualified from driving for three years after her release.
