Last week I was travelling south to Coffs Harbour on the Pacific Motorway through a construction zone in Ewingsdale. I was in an 80klm per hour zone doing approx 75klm when a temporary road sign was picked up by the wind and flew rapidly towards the front of my car. It caused me to panic swerve and slam on the bracks. The car behind me also had to brake and workmen who were approx 60 metres behind me to the left looked up to see what the commotion was. Just yesterday I was issued with a speeding fine for travelling at 76klms per hour in a 60 zone in about the same area as the sign nearly hit me. I have been a very careful driver, being a sales rep doing about 80,000 per year and never been charged with a serious offence or lost my license or even had an accident in more 20 years. I noticed that all the other signs are weighted down with green sand bags. I couldn't tell exactly what the sign was. I remember it was large, white and had yellow stand as it went tumbling towards me. Now I wonder should I defend the ticket in court and use this as my defense. And what about the cars behind me they probably got a ticket too, and they also should be set free under Traffic Law?
