NSW trucks deregistered for tunnel delays THREE trucks have had their registration suspended after becoming stuck in Sydney tunnels and causing lengthy traffic delays. Their drivers are the first to be hit by state laws introduced in July. Roads Minister Duncan Gay said one over-height truck drove into the Eastern Distributor last Friday. It caused damage to the sprinkler system and more than two hours of delays on the busy road. Mr Gay said the truck was deregistered for three months and the driver was being penalised for failing to stop. Another two trucks have had their registrations suspended for 28 days after they closed the Sydney Harbour Tunnel for 20 minutes in separate incidents this month. Mr Gay said there were $2200 fines and demerit points for truck drivers with over-height loads, but the message was not getting through. "New laws were introduced in July this year which allow us to hit operators where it hurts and suspend a vehicle's registration for up to three months if it's driven into a tunnel when over-height," he said in a statement. Mr Gay said the drivers who affected the harbour tunnel "ignored countless signs and warning devices" and had to be reversed out of the tunnel. In yet another instance, a West Australian operator had his visiting rights in NSW revoked for three months for closing the Sydney Harbour Tunnel for 20 minutes last week.
