A dog walker was killed in a freak accident when a tyre flew off a trailer and hit him as he walked his dog next to a busy dual carriageway.
Peter Smith, 79, was hit by the wheel after it was dislodged from a livestock trailer and struck him in the chest as he walked his German shepherd.
He was knocked unconscious and pronounced dead at the scene of the accident, which happened on the A38 near Newton Abbot, Devon, in September last year, an inquest heard.
A post-mortem examination later confirmed that the cause of death was chest injuries.
The freak accident has prompted calls from Smith's family for a change in the law around trailers.
An inquest in Plymouth heard that the wheel had come from a livestock trailer being towed by a Mitsubishi L200 on the day of the crash.
Coroner Andrew Cox, who recorded a verdict of accidental death, was told that a safety report carried out on the trailer found a number of faults and said it hadn't been regularly maintained for more than four years before the incident.
The law doesn't currently require trailers of a certain size to be registered and have an MoT.
Following the inquest, a member of Mr Smith’s family said: "I want to change this law as it’s not right.
"I don’t want the same thing to happen to anybody else."
The inquest heard that Mr Smith's dog was found at the scene and was being looked after by his family.
In a tribute to him at the time of his death, the 79-year-old's family said: "Peter was a caring and devoted dad, granddad, friend and dog lover.
"He will leave a void in everyone’s life whom had the pleasure of knowing him."
