Yes, in this case the dumb person was towing too heavy a load, and then tried to overtake at high speed.

The MORE weight you can put on the car the better. Have a look at a 5th-wheeler, or better yet a conventional semi, half the weight is on the Prime Mover. But your car's rear-end needs to be able to take the weight, and the hitch must be up for it, and most are not.

5th wheel and semis are substantially different in that the hitch is above the rear axle. Massively different to an overhung hitch.

I would disagree on the weight.That looks to be aroun 5.5-6 metre open boat which would probably weigh around 15-1800 kgs,but I would presume that the ball weight was too low. Looking at that trailer it would appear that it probably has some sort of half*****d mods to fit a bigger boat than it was intended to have on it,resulting in too much boat behind the wheels resulting in too little ball weight.I would agree that I would much rather have 15% or even 20% ball weight if the tow vehicle would handle. 250 kg on the ball and you could tow that boat at 120km/h no problem.

It was excessive speed with driver over correcting with the steering that caused the accident, you can clearly see him nearly going off the verge of the road then tries to correct abruptly in which he loses control. Nothing to do with weight or incorrect boat trailer. |

Yeah the difference is 25% is about optimal for fifth wheel, and 10-15% is best for conventional. The people insisting less is always better or “no more than 5% because my owners manual says so,” are saying that because they’re not really talking about vehicles designed for towing. If you can’t put 10-15% of your trailer load on your hitch, because it will sag and overload the rear axle, then it’s too much trailer weight for that vehicle. Yes, you can shift more load toward the rear of the trailer to help level it, strap on your towing mirrors and away you go, but you’re dealing with compromises. It may be fine as long as you understand it. Now pull that same trailer with a vehicle designed to take the load, load the trailer properly so 10-15% is on the tongue, tell me which towing experience was more stable.

Really?
Oh wow, thanks for telling us! And there was me thinking my AU was the same as a Kenworth ![]() In point of fact the overriding principle remains the same. You want to put as much of the weight as possible on the towing vehicle, but yes, as I said, the strength and nature of the car and the hitch limits that.

![]() Best way to tow IMO. Seems a lot of towing accidents started showing up around the same time they allowed higher speed limits for towed trailers a couple of years back.

Lot of factors for more crashed.More caravans on the roads,but the biggest probably is people towing bigger heavier vans with unsuitable tow cars.How many times do you see 7.5-8 metre caravans weighing around 3 tonnes being towed by Ranger size vehicles.All good til a strong gust of wind or a bit of broken road surface and away everything goes.Big difference between towing a trailer loaded with building materials and a 3 t hollow box/ windsock with an 8sq metre wall in the front.

We've now got people saying more than 15% - where should we stop, 30%, 50%?.
Why don't we all just buy tilt trays and put our trailers on that, would be much safer. Of course there are compromises, no one said there isn't. What I and others have said, is that you can tow heavy trailers with less than 10% ball weight safely. I've done thousands of kilometers doing so, but I suppose I've never tried to overtake at +120km/h on a single lane highway with an unsecured load either ![]() I'm happy doing 80kmh safely towing my 2T load. It's the compromise I'm willing to make. I also pull over when i can to let others pass, I'm in no hurry. If a driver can't tow safely at 5-10% ball load, it says more about the driver than it does the tow vehicle and trailer. Maybe there needs to be some form of licence to tow more than 750kg, ie a braked trailer, so numptys like the guy in the video are taught some of the basics, but for some I doubt even that would help. Sometimes you can't help stupid. |

One thing these videos demonstrate is the danger of the pressure wave at the front of Semis, and the effect they have on vans, indeed cars themselves.

4WDs, big US pick ups, family sedans, Mid sized euros, box trailers, large vans, even an empty trailer. So either nothing is safe, or the way they were loaded and driven was unsafe. |

Modern dual cabs and wagons actually tow quite well if they are set up properly and within the manufacturers ratings and driven at appropriate speeds. Many just never read their owners manual to find out that info. Crash statistics also point out that crashes involving vehicles towing are a very small percentage of overall crashes on the roads. Most accidents are caused by the device between the steering wheel and the seat.

Trailers on a Semi are connected directly over (or slightly to the front of) the drive axles. Which, as you would know, helps eliminate the 'tail wagging the dog' effect.

i believe its also one of the reasons why 'pig' trailers are not very common these days, as 'dog' trailers are much safer.

Note that accident was on the M1 at Berowra entrance lane, flat stretch of the freeway so he must have been racing the BA wagon next to him. Points for keeping it upright.

you have to get a licence to drive a car/truck/motorbike etc yet people crash them every day. a licence is not a solution. its just more red tape and expense. Perhaps what people really want is some form of mandatory training. I believe these facilities already exist but are voluntary. I still don't see the need. These opinions are often put forward by generations who had very little in the way of training for any licence aquired back in those days. Rather ironic really.

Considering that Modern Vehicles have the ECU set to, disable any parking sensors/Reverse camera's while ever there's a trailer being Towed. It'd be very simple to set It up so the vehicle Can't go faster than (say) 90kmh whilst Towing..
The euro's recommend a lower Towing speed limit for a reason..! |

The English one at the end, towing a Transit van on a car trailer. the driver should have gone to prison for the stupidity.
