An investigation by the police watchdog, into a collision which killed an officer and a 91-year-old woman in Berkshire, has been completed.
Thames Valley Police (TVP) says it has reviewed how it conducts training exercises, after the deaths of Gladys Goodwin and PC James Dixon in December 2017.
PC Dixon's motorbike collided into the side of a Toyota car - where the elderly woman was a passenger - on the A4 near Wargrave in Berkshire.
The force says it is going to use training exercises to make it clear to officers whether speed restrictions apply, but said PC Dixon did follow protocol.
IOPC Regional Director Sarah Green said: “Following the conclusion of the recent criminal trial, I extend my condolences to the families and everyone affected by the death of Gladys Goodwin and PC James Dixon.
“At the end our investigation we provided our findings to TVP and HMRC and offered to arrange a debrief to discuss organisational learning, which needed to be addressed by the agencies involved in this training exercise.
“We found that although the training exercise PC Dixon was taking part in did adhere to policy and procedures, improvements could be made to ensure all officers are aware of when speed exemptions are applicable or not.”
The driver of the car in which Mrs Goodwin was a passenger - a woman from Crowthorne - was acquitted of two counts of causing death by careless driving on 21st January 2020.
This followed a trial at Reading Crown Court.
