Motorcyclist Protection Rail Systems

Guardrail safety barriers are effective in the containment and redirection of passenger vehicles, however they may cause injuries to a dismounted motorcycle rider. Motorcyclists are classified as vulnerable road users and designers should consider the features of the safety barrier system to minimise harm.

The exposed posts of a guardrail safety barrier system present a significant risk to motorcyclists. The installation of a motorcycle protection rail system or rub-rail is considered the most appropriate treatment solution. The rub-rail is positioned underneath and parallel to the guardrail beam, shielding the guardrail posts. The rub-rail panels are typically supported by spring brackets that absorb the impact energy of a sliding, dismounted motorcyclist rider.

Motorcyclist Protection Rail Systems FAQs

When should I specify a Motorcyclist Protection Rail System?

Designers should consider state road agency specifications and the frequency of motorcycle riders using the roadway. Typically, the risk of a dismounted motorcyclist increases on concave curves.

Can a Motorcyclist Protection Rail System be retrofitted to existing guardrail systems?

Yes. In most cases the Motorcycle Protection Rail System can be retrofitted without dismantling the existing guardrail barrier system.

How do I terminate the end of the Motorcyclist Protection Rail System?

The last panel of the Motorcyclist Protection Rail System should be fitted with a customised bullnose to shield motorcyclists from potential snag points.

Can a Motorcyclist Protection Rail System be secured to the guardrail end terminal?

No, a guardrail end terminal is specially engineered to reduce the potential for vehicle spearing during end-on impacts. A Motorcyclist Protection Rail System could compromise the function of the guardrail end terminal or become detached during a vehicle collision presenting a hazard to other road users.

What motorcyclist protection treatment options are available for guardrail end terminals?

A plastic cover is available for placement over the impact head of a guardrail end terminal shielding potential snag points for motorcyclists.
