Safety experts say other areas in the UK could learn from seminars run in Lincolnshire to reduce road deaths.
The county was the first to introduce courses to force motorists to confront the consequences of going too fast.
Speeding drivers are offered a place on a seminar as an alternative to getting a fine and points on their licence.
The scheme, which was introduced in 1999, includes graphic accounts from victims' families, and is being rolled out across the UK.
Insp John Morris, of Lincolnshire's Road Partnership, said organisers of other seminars could learn valuable lessons.
He said: "We're very forward-thinking, we're happy to comply nationally with what other counties are doing, what the government want and everything.
"We have been doing this for six years - we were the first force to actually do something like this, as an education and this is hopefully why we're confident they will come and look at our product and see what we do."
