It's happened a number of times this summer.
South Western Ambulance Service tweeted to say "In an emergency, every second counts."
The service says it has struggled to reach patients several times this summer due to parked vehicles.
They've issued advice asking people to allow at least 10 feet for emergency services vehicles to pass by safely.
