Around a station, near a school, I can just about see a justification as this involves daytime parking issues. But beware, fines make up a big proportion of a council's parking 'profit', so those guys buzzing around on scooters will be issuing PCNs for the slightest infringement. Although there would be no excuse for parking outside of our allocated zone without a permit, or on a yellow line at the wrong time, or thoughtlessly blocking a ramp or an access road, I guarantee even the most cautious driver will get tickets. From my time in a CPZ, my neigbours and I recieved PCNs for the following spurious reasons: In the five minutes we were inside scratching off the dates on the day pass (?15/book valid only for two years) to place on a relative's car For having one wheel over the white line at the end of the CPZ (even though the other wheel was in). Clamped and removed because the disc fell from the screen while we were away on hols in hot summer of 2003 (in the plastic holder provided by Lambeth) because the permit number (but not the date) was slightly obscured. ?280 to get the car back. On a buider's van in the time it took for him to carry his stuff to our door and before we could give him his vistor's pass None were successfully appealed. Be careful what you wish for.
