While education is the key, it must be COMPULSARY education, and the easiest way to manage that is through a licencing system if you wish to tow anything. Voluntary training will assist, particularly when towing a caravan, remember though people tow so many other things than caravans.
Below are three examples of accidents I have been to in the past 10 years involving trailers, the information is gained from police reports and witness statements
1. 2006 A Male attends a service station and hires a car trailer, fills out the required paperwork, hands over his hard earned. The attendant helps to hook up the trailer to a 1985 ZL Fairlaine (Tow capacity max 1600kg) with a light duty towbar, runs the hirer through the operation of winch and ramps and checks trailer lights.
Hirer takes trailer home and loads a VP commodore onto trailer (Kerb weight 1362 kg), then continues to load commodore with household items and flat pack furniture (estimated 500 kg). So 1862 kg + the weight of the trailer, another 600 kg, a total of 2462 kg, well above the capability of the Fairlaine, and certainly above the home made towbar.
Hirer begins to travel North of Adelaide into an 80 kph zone, where he finds the trailer is too heavy on the back of the fairlaine (downforce), so stops and moves commodore backwards until it all sits level (by eye). He then continues on his trip. (worth noting the commodore is only held onto the trailer by the winch, no additional tie downs). Time is now approx. 9pm.
Once the hirer hits a 110 kph zone and begins to speed up. At 95 kph the trailer begins to wobble violently and is uncontrollably, resulting in the trailer rolling and the commodore rolling independently, the fairlaine tips onto it's side and stops, driver escapes without injury. Unfortunately, coming in the opposite direction at that exact moment is another car with 2 occupants, unable to avoid the carnage they hit the commodore, sending it spinning on its side into the fairlaine, the trailer rolls onto the bonnet of the oncoming care and slides up, partially removing the roof of the car and decapitating the 2 occupants (remember this was at the same time as the trailer rolled).
Result 2 fatally injured, both innocent parties.
Being a hire trailer, voluntary education, with lower premiums on insurance or lower registration fees would not have worked. Compulsory education (ie a licence) may have worked.
2. 2014, Again a driver hires a car trailer, this time tri axel, hooks up to a D22 Navara, with 3 tonne towing capacity, dives to pick up a ski boat and trailer. As the boat trailer is not yet roadworthy, driver loads the boat/trailer combination onto the car trailer. To ensure the Navara does not sag too much, the boat trailer is loaded towbar first. This means that the boat trailer axels are behind the car trailer axels, so the majority of the weight is on the rear of the trailer.
Driver travels 400 km at 80kph before commencing a steeper decent where his speed increases, the trailer begins to wobble uncontrollably and the driver applies the brakes to attempt to slow down. Trailer rolls 1.5 times landing upside down, with the boat ejected 30 metres from the accident scene. the trailer has disconnected from the Navara, after the Navara has rolled onto its roof.
Result, sole occupant suffered non-life threatening injuries, however is now a quadriplegic.
Again, voluntary education would not have helped, compulsory might have.
3. 2015, A driver takes his 6x4 box trailer, towed by a 2015 Hilux, and buys 500kg of animal feed, in bags, and begins to travel home. After hitting a bump at 100kph, the trailer bounces heavily, lands crooked and rolls, breaking the drawbar, this also caused the hilux to roll onto its side, landing on a rural fence strainer post. The post passes through the driver's window and hits the driver's headrest, millimetres from the drivers head, the force breaks the headrest from its stems into the seat. Driver walks away with sore pride and written off week old car, no injuries (mm from potential fatality).
In all three of these cases, voluntary education would not have worked. Compulsory education may have reduced the risk. I know that the licencing of driver's may not be the perfect answer, lets face it we still have licenced car, truck, bus and motorcycle driver's doing stupid things. Lets face it, how long have we been educated not to drink and drive??? Or wear seatbelts?? Or drive to the speed limit?? All of which continue to happen and be major causes of death and injury.
The most dangerous way to tackle this increasing issue, is to do nothing and maintain the status quo. Letting natural selection happen has, and will, effect innocent people, not the stupid ones.
