Hi everybody, Feeling dumb. Why don't quad bikes need roll over protection? PUWER says do a risk assessment to see if you need ROPs and quad bikes seem to roll over on a regular basis ( please note I am Daily Mail reader ). Are farmers getting lots of claims they can't defend due to lack of ROPs. Serious question foe me - please comment.

Hi martin1 Some organisations are against fitting ROP as, they state, international research indicates more injuries / more severe injuries are caused when fitted.

Hi Martin1 You are correct - the law does ostensibly require quad bikes to be fitted with ROPs and this is technically an "absolute duty", subject to a caveat, and indeed a number of celebrities have been seriously injured in quad bikes rollovers (Ozzie Osbourne, Rik Maile) as well as the normal crop of ordinary workers. However, some years ago the HSE commissioned a research project which produced a computer simulation of a roll cage and concluded that these made the bike more unsafe. A senior HSE inspector publicly stated that quad bikes didn't require ROPs. No actual testing to confirm the results ever seemed to be carried out and I have to say that if it works for tractors where there's a legal requirement I've never understood why quad bikes are any different. If they flip backwards on a slope a simple roll bar seems likely to give you some protection from being crushed. If you go over forwards things might be different. It's probably down to the type of tumble you have. I'm not sure how many types of roll cage were considered by the HSE research - possibly only one. Given you face an absolute duty in law, a defence based on theoretical computer modelling without any practical testing seems rather weak. There are people making roll-bars so it is possible to fit them. I think if I used one every day on rough terrain, I'd fit one to protect myself, but I've never ridden one. Regards Dave

Are seat belts required?

No. Because it qualifies as a bike. Logic suggests you would likely be ejected from the seat in the event of a roll over and would likely be crushed by the roll cage. Also, the addition of a roll cage would raise the centre of gravity and increase the likelihood of roll over.

Dave,All Thanks - useful responses. ref "absolute duty": PUWER doesn't make it an absolute duty by my reading but asks you to do a risk assessment of risk of roll over. Probably an absolute duty by default though as you would have to be able to prove 100% that roll over was not an issue. Must be a few other pieces of kit - like the quad bikes - that you ride but don't have roll cages due to their size? Ride on mowers?

Bicycles.

ROPS are only safe if the driver is restrained in the seat. The better question would be; Are quad bikes appropriate for the task? Other small, lightweight ATV's are available that have seated driver positions, belts and ROPS.

To operate (ride) a sit-astride ATV safely the rider needs to be able to move their centre of gravity relative to the vehicle (e.g. to the inside of the corner when turning). This is particularly important because you obviously can't lean a quad into a corner like you can a bike. Consequently a seat belt is not practicable and as Mr Smurf says a ROP is only safer if the driver is restrained inside the protected area. Hence no seatbelts and no ROPS

Regarding the use of seatbelts, it's true that a full ROPs would require a restraint system, but a full ROPs would also not be practicable. There are other options which claim to provide a "fighting chance" if you do have a rollover. The demonstrations seem credible.

HSE research found no benefit to the driver of an atv (quad bike) with a ROPS but that it was more likely to increase the significance of harm. Instead, HSE insists on proper training, active riding and the wearing of an helmet. http://www.hse.gov.uk/re...rr_pdf/1999/crr99222.pdf http://www.hse.gov.uk/pubns/ais33.pdf In New Zealand they do use a form of ROPS on atv's: http://www.acc.co.nz/PRD..._promotion/wpc086719.pdf

I have had some experience of quad bikes when I was working for a seismic organization in the UK, they were always under some discussion as to what is right and wrong use. Risk assessments were completed, but nothing on ROPS, I believe on the road they are subject to a set speed of 20mph, though they are capable of much more but minimum use on road was advised due to low speed, full face crash helmet though not compulsory. Off road, we were only allowed on level or slight incline (forget what angle and operator had to judge this in his training), again speed limit of 20mph or less depending on terrain. When we were working across farm land, I have seen farm workers going like a bat out of hell across land and roads? You can get some legal information from various websites that sell them and Dept of Transport though nothing about ROPS. https://www.gov.uk/quad-bikes-the-rules
