The partnership began in 2021, when there were 47 deaths recorded on roads and 647 serious injuries.
The latest figures have shown a slight increase in 2023, with 48 deaths and 702 serious injuries.
Adrian Leisk, from the partnership, members were not disheartened as the partnership was still relatively new and more work needed to be done.
He said: “I’ve knocked on doors to tell people that their loved ones are not coming home, I’ve also stood at crash scenes surveying the devastation, so, personally, I have bought into this.
“We need to work harder; we need to engage more partners.
“We are going to Westminster to highlight what we are doing down in the South West because we are recognised now across the country as driving innovation and changing the way we approach road-related harm.”
Christ Boston, from Devon and Somerset Fire and Rescue Service, said the objective was simple.
He said: “If we can get to one person today, and get that message across to not drink and drive, not do drugs, to put that seat belt on for a short or long journey, look after each other in the car, and be a sensible driver, then we have done some good.”
