Is it illegal to drive with one side mirror missing?
In many places, driving with a missing side mirror is illegal or treated as an equipment violation, and you can be cited. The exact rule depends on where you are.
Laws governing exterior mirrors vary widely by country, state, and province. Some jurisdictions require two exterior mirrors on passenger vehicles, while others mandate only a functional driver-side mirror plus a rear-view mirror, with penalties for driving without the required equipment. This article outlines the general landscape and offers practical guidance for drivers who discover a missing side mirror.

United States
The United States relies on state-level rules for exterior mirror requirements. Federal standards (FMVSS 111) govern visibility and mirror performance, but enforcement and the exact number of required mirrors are set by individual states. Some states require two exterior mirrors on passenger cars; others require at least a functioning driver-side mirror and a rear-view mirror, with the passenger-side mirror either required or optional depending on the vehicle. If a mirror is missing, you can be cited for an equipment violation, and you may be required to replace it promptly to continue driving legally. Always check your state's DMV or transportation department for the precise rule in effect where you are driving.
Canada
In Canada, exterior mirror requirements are provincially regulated. Most provinces expect functioning exterior mirrors on both sides for typical passenger vehicles, and violations can lead to fines or penalties if a mirror is missing or damaged. Replacement should be arranged promptly to stay compliant and maintain safe driving visibility.
United Kingdom and Europe
Across the United Kingdom and the European Union, vehicles are generally expected to have exterior mirrors on both sides, and missing or damaged mirrors can be illegal and subject to penalties. The exact wording and penalties come from national regulations and EU directives, which require adequate visibility for the driver. If a mirror is missing, you are typically advised to replace it as soon as possible to avoid enforcement actions.
Australia
Australian road rules typically require functioning exterior mirrors on both sides for most light vehicles. A missing mirror can lead to penalties or a stop by law enforcement, and drivers are encouraged to replace the mirror promptly to maintain compliance and safe operation.
Note: The above summaries are general and meant to provide a broad understanding. Always verify the specific requirements with the official transportation or road authority in your jurisdiction before driving.
If you find yourself with a missing mirror, here is a practical approach to stay safe and compliant while you arrange a replacement.
What to do if your mirror is missing
- Check the exact rules for your location by visiting your state/province or country's official transportation department website or calling their helpline.
- Do not rely on the missing mirror for safe driving; adjust your other mirrors to minimize blind spots and drive with extra caution.
- Promptly arrange a replacement mirror—many auto parts stores offer same-day or next-day installation, and mobile repair services may be available in your area.
- If you must drive before replacement, limit trips to essential ones, avoid busy traffic, and consider using a spare vehicle with all mirrors intact if possible.
- Keep documentation or receipts for the replacement in case you are questioned by law enforcement or during vehicle inspections.
In short, missing exterior mirrors can be a legal issue in many places and a safety concern regardless of the law. Replacing the mirror as soon as possible helps ensure compliance and reduces blind-spot risk on the road.
Summary
The legality of driving with a missing side mirror varies by jurisdiction, but most regions require functioning exterior mirrors for safe operation and may treat a missing mirror as an equipment violation. Always verify the exact rule with the local or national transportation authority, replace the mirror promptly, and drive with heightened caution if you must operate the vehicle before repairs are completed.
