In brief: replacing wing mirrors with cameras is not universally legal. Some regions allow certified camera-monitoring systems (CMS) as an alternative to exterior mirrors, while others still require traditional mirrors or only permit CMS in specific, regulated configurations. Regulations vary and can change, so check your local rules and your vehicle’s specifications.
This article examines how rules differ by region, the practical implications of such a replacement, and what you should consider before pursuing a camera-based solution.
Regulatory landscape by region
Here is a snapshot of current rules in major markets to help you understand where a camera-based replacement might be possible.
- United States: Exterior mirrors are mandated by federal regulations (FMVSS 111) for most passenger cars. As of 2024, there is no nationwide approval for replacing exterior mirrors with cameras alone. Some manufacturers have explored CMS concepts or offered models with camera-based features, but these do not generally eliminate the need for compliant mirrors.
- European Union and United Kingdom: Camera-monitoring systems are permitted as an alternative to exterior mirrors on new vehicles in many cases, provided they meet UNECE Regulation No. 46 (and any relevant amendments). Several models in these markets offer CMS options that comply with the standard, though availability varies by model and country.
- Australia and New Zealand: External mirrors are typically required under current design rules. While there have been trials and discussions around CMS, a broad, nationwide allowance for replacing mirrors with cameras has not been established. Always verify current local approvals and vehicle type-approval.
The regulatory picture matters because it directly affects what you can legally install and drive on public roads. If you’re considering a CMS or a camera-only setup, you should confirm with local transport authorities and your vehicle’s manufacturer or dealer what is approved for your model and year.
Key considerations before replacing with cameras
Before deciding to pursue a camera-based replacement, weigh these practical factors to avoid legal trouble or safety gaps.
- Legality and compliance: Verify whether a CMS or camera-only setup is legally allowed for your vehicle in your country, state, or province. Non-compliance can carry fines or affect insurance and resale.
- OEM vs aftermarket: Original equipment manufacturer (OEM) CMS options are typically designed to integrate with the car and preserve warranties, whereas aftermarket systems may vary in quality, calibration requirements, and regulatory acceptance.
- Installation and calibration: CMS generally requires precise alignment and calibration to ensure the field of view and depth perception match safety standards. Professional installation and calibration are usually necessary.
- Cost and maintenance: Upfront costs can be substantial, and ongoing maintenance (camera cleaning, lens protection, software updates) is important for reliable performance.
- Performance in adverse conditions: Cameras can be affected by glare, rain, snow, and low light. Look for systems with high dynamic range (HDR), multiple cameras, or enhanced image processing to mitigate these issues.
- Driver training and user interface: Display placement, latency, and how the image translates to depth perception can affect driving behavior. Some drivers adapt quickly; others may require a transition period.
- Warranty and resale impact: Some warranties may hinge on maintaining original equipment, and future buyers may be wary of non-standard CMS installations. Check how a CMS affects resale value.
If you decide to pursue a CMS or camera-based replacement, work with a reputable supplier and ensure any installation is compliant with local regulations and the vehicle’s warranty terms.
Summary
The bottom line is that replacing wing mirrors with cameras is not universally permitted. In regions where CMS replacements are approved, they must meet applicable standards and be properly calibrated. In many other markets, traditional exterior mirrors remain mandatory. If you’re considering a camera-based solution, start by confirming the regulatory status for your location and vehicle, then consult a qualified installer or your manufacturer to ensure a compliant and safe setup.
