ATV and side-by-side rollovers on the farm: why they happen and what Alberta's rules cover

On a farm or acreage, the ATV or side-by-side is often the machine everyone uses and nobody thinks about. That's part of the risk. Here's what Alberta's injury-prevention and farm-safety sources say about rollovers, and what the rules do and don't require of you.

How often rollovers happen

The Injury Prevention Centre at the University of Alberta says rollovers cause more than half of quad deaths. Using Office of the Chief Medical Examiner data for 2009 to 2019, it reports that an average of 13 people die each year in Alberta on quads, with almost 600 hospital admissions and almost 5,000 emergency department visits. MyHealth Alberta gives a figure of around 15 Albertans dying each year in ATV crashes, and says most deaths happen when the ATV rolls or flips. The two sources use different periods and wording, but they agree that rollovers are the main way people die on these machines.

What causes them

The Injury Prevention Centre lists four common causes:

• Steep hills, whether you're riding up, down or across them
• Overloading with passengers or cargo
• Speed
• Sharp turns, even on level ground

The Canadian Centre for Occupational Health and Safety (CCOHS) adds the machine's design: a high centre of gravity, a narrow wheelbase and no operator protection all make a rollover more likely.

On farms, location matters too. The Canadian Agricultural Safety Association (CASA) looked at farm machine rollovers in general, not just ATVs. It found that most sideways rollovers happen near farm and rural roadways, when a machine is driven too close to the edge of a ditch. In the Canadian Agricultural Injury Reporting data it cites for 1990 to 2004, sideways rollovers made up about 61.5% of rollover deaths on farm machinery.

Where chores raise the risk

Those causes map onto everyday jobs:

• Spraying or carrying feed: a full tank or a load of bales raises the centre of gravity, and liquid shifts in turns. Keep cargo within the rack and towing limits in your owner's manual. Our guide to loads, towing and attachments explains how to read those ratings.
• Checking fences and ditches: side slopes and ditch edges are where the CASA findings point. Pick a line further from the edge, even if it's slower.
• Moving people: the Injury Prevention Centre says don't ride double. Most ATVs are built for one rider, and a passenger makes the machine harder to balance.
• Unfamiliar ground: CCOHS recommends checking your manual for slope limits and walking a hazardous route before you drive it.

What the safety bodies recommend

• Ride actively. The Injury Prevention Centre calls active riding, using your body weight and position to keep the quad upright, a skill every rider needs, and recommends a quad safety course to learn it.
• Use the right size of machine for the rider and the job.
• Consider an operator protective device. The Injury Prevention Centre describes crush protection devices for quads, sold under names such as QuadBar and ATV Lifeguard, that are designed to stop the quad on its side or leave space for the rider if it rolls.
• On side-by-sides and tractors, use the rollover protection and the seatbelt. CASA says rollover protective structures combined with seatbelts help protect operators, and that riders should only be carried if there's a seat designed for them.
• Ride sober. The Injury Prevention Centre says alcohol was found in 55% of drivers who died, and most of those (75%) were over the Criminal Code limit of 0.08 blood alcohol content.
• Wear a helmet. The same source says 8 out of 10 people who died of a head injury weren't wearing one. Our post on Alberta's helmet law and farm exemptions explains when the law requires one.
• Set safe work procedures if other people use your machines. CCOHS recommends setting safe work procedures for off-road vehicle work.

What Alberta's farm safety rules actually require

This is where a lot of farm safety advice gets the law wrong. According to the Government of Alberta:

• Farm and ranch OHS requirements apply only where you employ at least one waged, non-family worker, and then only to those workers. They don't apply to family members, the private residence, or recreation such as riding or hunting on your own land.
• For those operations, only the basic standards in the Occupational Health and Safety Act apply. The OHS Regulation and most of the OHS Code don't apply to farms and ranches. The exception is the Code's rules for joint health and safety committees and health and safety representatives, where a farm has them.
• Employers must ensure the health and safety of workers as far as is reasonably practicable, follow generally acceptable industry standards and apply general health and safety principles.
• Workers have three basic rights: to refuse dangerous work, to know about potential hazards, and to participate in workplace health and safety.

So the detailed equipment rules in the OHS Code don't apply to a farm the way they would to an industrial worksite. Industry standards and manufacturer instructions still matter, though. If you employ people, "as far as reasonably practicable" is a real duty, and following your machine's manual and safety bodies' advice is how you show you've met it. Our guide to Alberta's farm-use rules covers the rest.
