Thats a compilation of the ads that the TAC (Transport Accident Commission - the no fault third party insurer for Victoria, Australia) over at least 20 years. We have some very hard hitting ads here - some should really be R rated considering their graphic nature. The TAC has a financial interest in making sure that deaths/injuries are reduced as they pay for anyone not at fault involved in an accident - hospitals, ambulance, rehab. etc.
Victoria was also the first State to have compulsory seat belt laws and that saw about a 30% reduction in the death toll in its first year, back in the early 1970s.
Whilst there has been a dramatic decrease in the road toll Australia wide, its not just been TV ads, first up has been the leaps in vehicle design with hosts of additional safety features/construction materials that were not available 20 years ago, eg; air bags, deforming plastics, side intrusion bars, etc. The other big effort has been on road enforcement with random breath tests and roadworthy checks - I've been stopped about 4 times this year, twice at about 7am on the way to work and been "bagged".
The on road vehicle condition checks are proving to be a major safety initiative - only NSW has annual roadworthy tests (MOT type test), other States have tests on sale of a vehicle and then on road testing/inspections - about 1 in 70vehicles get pinged and about 1 in 1200 get put off the road in QLD (my State).
Its unfortunate that (un)professional drivers can still drive after being convicted of DD offences - something the transport union wont even consider is banning drink drivers from holding bus/truck/taxi licences.
