Paramedics were delayed for 15 minutes during an emergency call after an ambulance was blocked by a car down a narrow village street.
The Cornwall Fire and Rescue Service’s extrication team took to social media to post images of the incident, which happened in the small hamlet of Knave-Go-By, near Camborne.
They say police were called in after a bin lorry later struggled to negotiate its way around the vehicles.
“This ambulance was waiting for over 15 minutes trying to get through with the owner of the car nowhere to be found,” they wrote on Twitter.
“After this the bin lorry couldn’t get through and the police were called.”
It’s not the first time emergency services have been stuck because vehicles are blocking the road, and it won’t be the last.
Fire crews say poor parking is becoming an increasing problem for them as they try to reach burning homes and car crashes in Cornwall.
Fire chiefs are now urging people to think when they park and encourage better parking practices from local residents and holiday makers alike.
A spokesman for the fire service told BBC Radio Cornwall: “If we have cars parked irresponsibly on either sides of the road or especially in corners it can make it difficult to get through.
“It slows us down and adds pressure on our crews who are already under pressure to get to the job quickly.
“Life takes priority over a wing mirror which means that on occasion we will need to do what we need to do to get to that fire.”
In September firefighters launched a social media campaign using the hashtag #ThinkB4uPark to increase awareness among drivers.
Cornwall Fire and Rescue Service said: “The hashtag is being used across social media in the UK by other emergency services, who are experiencing delays in getting to incidents, due to badly parked cars or driving.

“The service does not endorse this campaign as a way and means of naming and shaming members of the public.
“It is to raise awareness and educate drivers to think about where and how they park.”
They added: “Those motorists that are not considering if an emergency vehicle can get past, are putting lives at risk by blocking off roads and even stopping on box junctions outside community fire stations.
“If your vehicle is considered to be parked inconsiderately, you may find one of our leaflets under your windscreen wiper – Think Before You Park notice.”
