A police watchdog has said it will not be investigating the death of a motorcyclist near to a Dorset Police speed camera van.
The motorcyclist, from Hampshire and aged in his 60s, died on the northbound A338 Bournemouth spur road on Saturday.
The accident was referred to the Independent Police Complaints Commission (IPCC) because of the "proximity" to a stationary van.
However the IPCC has decided there was no need for a "formal referral".
The victim has not yet been named but his family has been told.
The A338 was shut in both directions between the Cooper's Dean Roundabout and the Ashley Heath Interchange, causing severe congestion.
Specially trained traffic officers are investigating the incident and have appealed for witnesses to the crash.
Insp John Mallace, of Dorset Police, said: "My thoughts are with the family and friends of the victim at this difficult time.
"Our highly skilled investigators are now reconstructing what took place with the aim of not only informing the family of what happened but also to work towards reducing road casualties further.
"I'd also like to thank the members of the public who stopped to assist at what was a traumatic incident."
