CAR wars have broken out between Quedgeley residents and parents picking up their children from school.
One driver said the situation near Field Court Junior School had become so bad that parents were arriving early to grab a spot. She said: "It's like fighting for sun beds in Benidorm."
Twelve trainee police community support officers descended on Courtfield Road as part of their eight-week course to become officers.
They help to calm a situation which is frustrating for residents and parents alike.
Pensioner Jutta Macaulay, 84, said: "I can't wait for the school holidays. It is a nightmare.
"I have lived here for 34 years, since the house was built, and the problem is getting worse. Some people don't need to use their cars to travel the short distances.
"I quite often have doctors' appointments to get to but I have to time them carefully otherwise I can get blocked in my own driveway."
Neighbour Tim Williams, who has lived there for 11 years, said: "Parents even park in people's driveways. That's how bad it has got.
"If there was a fire down here, a fire engine would have no chance in getting through."
Training officer Rhian Goddard, 20, from Churchdown, who planned much of the operation, said: "Most people don't realise that they can't park within 10 metres of a junction and today has been about informing and advising people. We haven't been issuing tickets."
The parking woes have proved the perfect opportunity for the trainees to get out and about on the streets for the first time.
Trainee Jess Hopton, 24, from Churchdown, said: "I enjoyed working as a special constable so I've been looking forward to getting back out meeting people. It's what we signed up for."
Training officer PC Kate Palmer said: "They have had to plan the operation themselves to every last detail."
