In most countries, vehicles are legally required to have at least two types of mirrors: a rear-view mirror and two side/wing mirrors (one on the driver's side and one on the passenger's side). These mirrors are important to enable the driver to see behind and to the side of the vehicle, which is essential for safe driving.
However, the exact legal requirements for mirrors can vary depending on the region and the vehicle type. For instance, heavy vehicles like buses and lorries often have additional or specialised mirrors. To ensure compliance, it’s best to consult local regulations or your vehicle manual. For example, replacing a damaged Ford Fiesta wing mirror with an approved equivalent ensures legal conformity and safe driving visibility.

When driving at night, the headlights of following vehicles can dazzle in the rear-view mirror – but there’s a remedy. Traditionally, interior rear-view mirrors can be tilted manually to reduce glare, allowing only part of the light to reflect while still offering a rear view. However, automatically dimming mirrors offer a more advanced and hands-free solution.
These mirrors use two integrated photo sensors to detect changes in light intensity: one sensor monitors the brightness ahead, while the other detects light coming from behind. When the sensor at the rear registers significantly more light than the front, the mirror automatically dims.
This dimming is made possible by a special coating on the mirror glass, containing electrolyte crystals, similar to those found in LCD screens. When voltage is applied to this coating, the crystals realign to reduce reflectivity, resulting in an instant and adjustable darkening effect. This ensures improved visibility and comfort while allowing the driver to keep both hands on the wheel.
Panoramic mirrors
Panoramic mirrors are a type of interior rear-view mirror designed to offer a broader field of vision than standard rear-view mirrors. While traditional mirrors show only what is directly behind the vehicle, panoramic mirrors use a convex or curved surface to expand the visible area. This curvature bends light to allow the driver to see a wider stretch of road and reduce blind spots.
These mirrors are especially beneficial in the following cases:
Larger vehicles: Commonly fitted in SUVs, vans, and minivans to enhance rear visibility.
Blind spot reduction: Helps improve awareness of surrounding traffic.
Limited mobility: Useful for drivers who have difficulty turning their heads to check behind them.
By offering improved coverage, panoramic mirrors contribute to safer lane changes and better overall rear visibility, particularly in vehicles with limited rear window space.
Adjusting the mirrors
Before setting off in a car that isn’t your own, whether it’s a family SUV or a compact model like the Ford Fiesta, it’s essential to adjust both your seat and mirrors to ensure a clear view and safe driving. Properly positioned mirrors can significantly reduce blind spots and improve rearward vision.
Follow these steps to adjust your mirrors correctly:
1. Adjust your seat first
Sit in your normal driving position with your back against the seat and hands on the wheel. This ensures the mirrors are set according to your actual posture.
Rear-view and side mirrors play a critical role in road safety by eliminating blind spots and improving visibility. Whether you opt for standard, panoramic, or auto-dimming mirrors, proper adjustment is key to safer and more confident driving. According to AUTODOC experts, choosing high-quality, well-fitted mirrors and replacing damaged ones promptly can make a significant difference in both comfort and road awareness.
FAQs
What mirrors are legally required on a car?
Most countries require at least two mirrors: an interior rear-view mirror and an exterior side mirror on the driver's side. Some regions also mandate a passenger-side mirror. Always check local regulations.
How should I adjust my side mirrors?
Position your side mirrors so that you can barely see the edge of your car while still covering the blind spots. The horizon should appear just above the centre line of each mirror.
How do auto-dimming rear-view mirrors work?
Auto-dimming mirrors use sensors to detect bright lights from behind. When brightness exceeds a certain level, the mirror darkens automatically to reduce glare.
Are panoramic mirrors better than standard mirrors?
Panoramic mirrors offer a wider field of view, making them useful in larger vehicles like SUVs or vans. However, some drivers may need time to adjust to the slightly distorted image due to the convex shape.
Can I install panoramic or auto-dimming mirrors myself?
Many aftermarket mirrors are easy to install, but for more advanced features like auto-dimming, professional installation may be recommended.
How do I know if my rear-view mirror is adjusted correctly?
Sit in your normal driving position and check that the mirror shows the full rear window. The aim is to maximise visibility of the traffic behind you with minimal view of the car interior.
