An island of four thousand nine hundred people with a working harbour has lorries on it, and the council's job is to keep them off the roads at the wrong hours rather than to pretend they are not needed.
Heavy vehicles may use Harbour Magu, the ring road and the two link roads at any time between six in the morning and nine at night. They may not use the four streets behind the school between seven and half past eight in the morning, or between half past twelve and two in the afternoon, which are the times children are walking.
Between nine at night and six in the morning no heavy vehicle runs anywhere on the island without a permit. Permits are issued by the office for concrete pours, for perishable cargo and for an emergency, are free, take an hour to get, and are refused for anything that could have been done in daylight.
Speed on the island roads is walking pace near the school, the health centre and the market, and sensible everywhere else. The council has no power to issue a fine for this and says so plainly. What it can do, and does, is withdraw a permit and refuse harbour ramp slots to an operator who has been reported three times, and that has proved a good deal more effective.
Report a vehicle with the time and the place. The office keeps a log and the log is read at every council meeting.
