Why Canada Still Rejects Mandatory Truck Side Guards

Why Canada Still Rejects Mandatory Side Guards for Trucks: Safety, Politics, and Pressure

The controversy surrounding side guards on trucks in Canada encapsulates a wider debate: How far should governments go to protect vulnerable road users, such as cyclists and pedestrians, from collisions with large commercial vehicles? This article explores the evolution of this safety debate, the evidence supporting side guards, the entrenched political and industry resistance, and the alternatives being considered at local levels.

What Are Truck Side Guards?

Truck side guards (technically known as Lateral Protective Devices, or LPDs) are rails or barriers mounted along the sides of large trucks between the wheels. Their purpose is to prevent pedestrians, cyclists, and motorcyclists from being pulled under the truck in a side collision, a scenario that commonly results in severe injuries or fatalities.

The Safety Problem: Vulnerable Road Users at Risk

Canada’s urban centers, particularly cities like Toronto and Montreal, have seen growing numbers of cyclists and pedestrians sharing the road with large commercial vehicles. Several high-profile fatalities have raised persistent calls for improved truck safety:

• Cyclists and pedestrians are most at risk from the blind spots and high ground clearance of trucks.
• A typical collision involving the side of a truck often causes victims to fall under the rear wheels, with tragic consequences.
• Support for side guards has grown among urban planners, cycling advocates, and some city governments, who see them as a proven countermeasure.

Evidence: Do Side Guards Save Lives?

International research from the UK, Australia, and the Netherlands consistently shows substantial safety improvements after the adoption of side guards:

• 62% reduction in cyclist fatalities involving trucks.
• 20% reduction in pedestrian fatalities in similar collisions.
• 6% reduction in serious cyclist injuries, attributable to reduced under-ride incidents.

Federal Resistance: Why the Canadian Government Says No

Repeated efforts to mandate side guards nationally have failed. Both Conservative and Liberal governments have dismissed proposals, largely on the basis of:

• Fatality Data: Officials cite national data showing an average of two cyclist and four pedestrian deaths per year from side truck collisions, representing less than 4% of all cyclist fatalities and less than 1% of pedestrian fatalities in vehicle collisions.
• Jurisdiction Arguments: Responsibility is claimed as municipal, not federal—implying that cities should design safer roads rather than the federal government mandating vehicle equipment.
• Cost Concerns: Both federal Canadian and US authorities argue that retrofitting side guards would cost between $600 and $4,500 per truck, and claim that the lives saved do not justify the expense.
• International Coordination: With the US not mandating side guards, Canadian authorities argue that cross-border trucking would be complicated and freight businesses harmed.

Lobbying and Industry Influence

Investigations have revealed intense pressure from trucking industry representatives, both in Canada and the US, resulting in regulatory inertia:

• Industry lobbyists repeatedly claim side guards are an expensive “band-aid” and advocate for technological alternatives such as electronic sensors.
• The US Department of Transportation (DOT) has allowed lobbyists to review and recommend removal of side guard references in regulatory drafts.
• Internal government reports have been edited to remove or downplay recommendations for side guard mandates, often citing industry arguments about economic impacts.
• Canadian federal agencies have been documented parroting US positions, leading to regulatory stagnation and delayed action in Canada.

Cost vs. Value: Are We Underestimating Lives Lost?

Safety advocates counter the cost argument by pointing out:

• Child car seats and airbags are legislated despite high individual costs and relatively low incidence of fatal accidents.
• School playground equipment was replaced at huge cost for safety, even without serious injuries.
• The cost of installing side guards is often less than a truck’s fuel bill; thus, cost objections are seen as specious when weighed against the value of human life.

Municipal Innovations: Toronto’s Local Response

With federal inaction, some municipalities have taken steps to increase safety:

• City of Toronto: As part of the Vision Zero initiative, Toronto has mandated side guards for all Solid Waste Management Services vehicles (both municipal and contracted).
• As of late 2024, 30 city vehicles have been retrofitted with side guards, funded through capital budgets.
• Toronto seeks to require side guards on all commercial vehicles operating within city limits, but lacks jurisdiction to impose the rule on non-city-owned vehicles.
• Additional measures include cabover chassis to reduce blind spots, high-visibility coloring (yellow and blue), convex mirrors, 360° cameras, and driver assistance/collision avoidance technology.

The US Debate: Lessons from South of the Border

The United States offers a parallel story of regulatory resistance, despite mounting evidence:

• The Insurance Institute for Highway Safety (IIHS) estimates side guards could save up to ten times the lives federal regulators claimed.
• Research from US, Canadian, and Dutch agencies demonstrates that particular designs could offer comparable protection to side guards at lower cost—yet implementation lags.
• Some US cities and states have piloted guard installation on municipal fleets; others await federal action.

Technological Alternatives and Complementary Measures

Opponents of mandatory side guards argue for alternative safety technologies:

• Electronic sensors for safer lane changing and collision warning.
• Convex and wide-angle mirrors to decrease blind spots.
• Driver assist systems to enhance awareness of surrounding traffic and vulnerable users.

However, evidence suggests these technologies can complement, but not replace, physical side guards, particularly in preventing under-ride injuries.

Counterarguments and Limitations

• Low Fatality Numbers? Critics of federal policy suggest official fatality statistics undercount the real toll by excluding non-fatal severe injuries and incidents that do not make national datasets.
• International Freight? While cross-border freight is cited as a complication, most deadly side collisions occur in city environments with local deliveries—not cross-border trucking.

The Social Value Argument

Advocates for side guards highlight the societal inconsistency in safety spending:

• Extensive investments are made to protect car occupants and schoolchildren, while vulnerable road users receive less attention despite similar risk levels.
• Side guards are relatively inexpensive per truck compared to many other required vehicle safety features.

Canadian Policy Timeline

• Early 2010s: Motions by city councillors (e.g., Olivia Chow) to mandate side guards are rejected at the federal level.
• 2013: Renewed calls after cyclist fatalities met the same fate.
• 2023: Olivia Chow becomes Mayor of Toronto, championing local safety reforms.
• 2024: Toronto reports back on feasibility and finances of retrofitting its fleet, mandates side guards for solid waste vehicles, seeks expanded provincial and federal requirements.

International Progress: Where Are Side Guards Required?

Frequently Asked Questions (FAQ)

Q: What are truck side guards and how do they work?

A: Truck side guards are barriers installed along the sides between the wheels of large trucks to prevent pedestrians, cyclists, and motorcyclists from being dragged under the vehicle in case of side collision. They significantly reduce the severity and frequency of such injuries and fatalities.

Q: How many lives could side guards save each year?

A: International studies estimate side guards could reduce truck-related cyclist deaths by 62% and pedestrian deaths by 20%, potentially saving dozens of lives annually in major Canadian cities.

Q: Why hasn’t Canada made truck side guards mandatory?

A: The federal government argues low fatality numbers, high retrofit costs, industry lobbying, and lack of similar requirements in the US. Municipalities lack legal authority to implement citywide mandates, but some (like Toronto) require them on local fleets.

Q: Are electronic sensors and mirrors as effective as side guards?

A: While electronic sensors, mirrors, and cameras can help prevent some collisions, they do not physically prevent victims from being pulled under truck wheels. Side guards provide unique mechanical protection, especially in dense urban settings.

Q: What can cities do if the federal government refuses to mandate side guards?

A: Cities like Toronto have begun requiring side guards on municipal and contracted fleets, and continue to lobby provincial and federal governments for broader regulations. Advocacy and public awareness are key to driving change.

Moving Forward: Policy Possibilities and Practical Steps

While federal resistance persists, the evidence for side guard benefits continues to grow. In light of ongoing fatalities and injuries, several practical steps can help move the issue forward:

• Mandate side guards for all trucks operating primarily in cities where pedestrian and cycling traffic is highest.
• Retrofit municipal and waste collection fleets, setting a public example.
• Invest in complementary technologies and design improvements to maximize overall truck safety.
• Continue public education and advocacy to expose the real toll of side collisions and challenge cost-based arguments.
• Monitor international best practices for new innovations in guard design and integration.

Despite continued political and industry headwinds, the path toward mandatory truck side guards remains a critical frontier in making Canadian roads safer for everyone.
