Upset motorists have gone as far as damaging offending vehicles and slashing tyres, the poll by webuyanycar.com showed.
Disgruntled drivers have also blocked cars in if they have been parked badly or have left notes on car windscreens.
Based on responses from 3,000 people, the survey showed that 25% have verbally attacked those they have accused of parking “crimes”.
Blocking access is the worst of the faults, followed by parking too close to another vehicle and “stealing” a space from a driver already waiting to take it.
Other tactics that cause offence include parking in a disabled parking space, parking on double yellow lines, parking on the pavement and parking outside someone else’s house.
Of those who have fallen out with people over parking, around a third have done so with people living close by, with some resorting to knocking on neighbour’s doors to object.
Paul Coulter, of webuyanycar.com, said: “Poor parking is a real source of frustration for Britain’s motorists. From our research it’s clear that drivers should stick to common sense rules and courtesy to avoid notching anyone’s anger into top gear.”
