well thats where your wrong... I have a kid, all be it on the way, and 3 neices... but ur all missing the point. We are NOT against it, however the way it is setup and enforced is rediculous in this case.
As geoff said... whats more dangerous? looking at your speedo 10 times a minute or keeping an eye out for children?
If they want to enforce these laws down to the minute or second, so there is no discrepencies and no excuses, ALL signs should have flashing lights to say that zone is now 40kmh. Its not hard, makes more sense and no driver can say "oh i didnt know" or "oh my watch says it was not".
And those complaining that say they do have kids, do you drop them off at 8am?
