Description

Rollover protection structures (ROPS) are metal bars, frames, or crush proof cabs designed to prevent tractors from rolling over and crushing their drivers.

Expected Beneficial Outcomes

Reduced fatal and non-fatal injuries

Evidence of Effectiveness

There is some evidence that ROPS prevent agricultural fatalities (Hard 2011, Reynolds 2000). Additional evidence is needed to confirm effects.

As the use of ROPS increased, agricultural fatality rates have fallen (Reynolds 2000). Agricultural fatality rates remain higher in areas of the United States where ROPS are least widely used and lower in the areas with the highest ROPS usage (Hard 2011).

Some researchers suggest incentives to encourage more farmers to install ROPS (Murphy 2010). For example, a New York state social marketing campaign incorporating rebates, messages, and other promotional activities increased ROPS sales (Sorensen 2008) and positively influenced readiness and intention to retrofit (Sorensen 2011). The campaign was demonstrated to be cost-effective within 3 years (Sorensen 2010).

The cost of a ROPS is estimated to be $400 to $2,000 per tractor, including installation (Reynolds 2000). Retrofitting all older tractors in the United States would cost approximately $1.2 billion, potentially saving 1,478 lives (Reynolds 2000).   

The effectiveness of ROPS is limited if drivers choose not to wear seat belts (Reynolds 2000).

Implementation

United States

A national, voluntary standard has made ROPS standard equipment on all new tractors since 1985. Retrofits are available for many older tractors, but this option is not often used.
