A motorbike rider shouted "no" as an Suffolk-based American servicewoman pulled out into the path of a motorcyclist who was killed following a crash, a court has heard.

Graeme Pratt was riding his Triumph bike behind Mikayla Hayes, 25, when she moved away from a junction on the A10 at Southery into the path of Matthew Day.

Mr Day, a 33-year-old father-of-one, died later in hospital as a result of his injuries sustained in the crash which happened at about 4pm on August 26, 2022.

Giving evidence on Wednesday Mr Pratt, who had been looking to turn right onto the A10 on his Triumph bike, had been sat behind Hayes at the junction.

Mr Pratt said he saw Mr Day's motorbike behind a car which was turning into the junction they had been waiting at with the bike "closer to the nearside verge".

Mr Pratt said he remembered Hayes' vehicle "moving forward" as the motorbike was "still travelling down the A10".

He told Rachel Scott, prosecuting, he shouted "no"  as he could "see what was going to happen".

The jury of six men and six women heard Mr Pratt's vision was "towards the bike" which he said the front of which "dipped" as if the brakes were grabbed.

He said he saw "the rider of the Yamaha separated from the bike and went up" into the air as did the motorbike to a height "level with the roof of the vehicles".

Mr Pratt said he was then "knocked off my feet" by Mr Day's bike which slid across the road into his bike.

The witness told the court Hayes moved out onto the A10 as if the vehicle "was pulling out on an empty road".

Hayes, of Snowdrop Grove, Downham Market,  has denied causing death by careless driving.

The trial continues.
