DRIVERS who flout Shenzhen's traffic laws face a bizarre punishment - they must stand on a busy intersection and wave a flag. The errant drivers are handed white flags bearing the words 'Don't break the law', and told to direct pedestrians across the city's teeming streets. 'It's really tough to stand out here for the whole day,' said one bus driver who would only give his name as Kang. He had been on the street for more than 10 hours because he allowed passengers to board his bus before arriving at a stop. Traffic police ordered Mr Kang to pay a $100 fine and then do his 'public service' preventing jaywalking. 'If I had a choice, I'd rather pay an extra few hundred dollars than stand out here all day long,' he said. All temporary flag-wavers have their performance evaluated by traffic officers at the end of the day. 'Usually people only have to be out here for one day, but if they don't do a good job they might have to come back the next day,' explained Mr Kang. Jaywalkers are also subject to practical punishments. When caught, jaywalkers are given a scarlet arm band and told to wait on the kerb until they have helped catch another three jaywalkers. Bernard Chan, a finance consultant who regularly visits Shenzhen on business, said: 'I remember a time when there were about eight people with red arm bands. 'Everyone knew they were there to catch jaywalkers so everyone was careful. And when a pedestrian was caught off guard, there would be a crowd of people chasing him - it's really very funny.'
