Legal clarity (RO & EU): principles & common mounting mistakes

Why the mounting method matters

In Romania and across the EU, the law doesn’t mandate how you fasten a plate (screw, clamp, magnet), but where it sits and how readable it remains: in the manufacturer’s designated locations (front/rear) and clearly legible at all times. If you want a clean, frameless look while staying compliant, a well-designed magnet-to-magnet system (such as MagSleem) keeps the plate in the intended positions, no improvisation needed. For a minimalist appearance without the suggestion of a bulky frame, ultra-slim options (like SuperSleem) preserve full readability.

Key takeaway: the law doesn’t prescribe the fastening method; it demands correct placement and perfect readability.

Legal principles in short (RO & EU)

  1. Mount in the designated locations (front/rear)
    Plates must be attached in the points engineered by the vehicle manufacturer. “Relocating” to nicer-looking spots (too low/high/offset) may breach the rule of using the designated supports. On honeycomb or aftermarket grilles, use hardware that clamps from behind the cells (blocks + extenders) to remain within the correct area - precisely the scenario a dedicated honeycomb kit is built for (e.g., MagSleem S).

  2. Readability and conformity
    It’s sanctionable if a plate cannot be read (dirt, ice, snow, glare from deformation) or is non-compliant (wrong font/stencil, covered elements). Bulky frames, tinted caps or reflective films may obscure characters, the blue EU band, or security marks.

  3. EU recognition & country sign
    The blue band with a country code is recognised EU-wide. International principles (Vienna Convention) call for a clearly visible registration number and state sign. For non-EU plate sizes, a universal system that lets you keep the intended positions and visibility is the correct choice (e.g., MagSleem X).

  4. Measures if rules are breached
    If plates are wrongly mounted, unreadable or non-compliant, authorities can order measures until fixed. Correct installation, periodic checks and the right accessories minimise these risks.

Common mounting mistakes (and how to avoid them)

  1. Frames/covers that clip characters or the blue band
    Even a small overlap can be treated as “cannot be read.” Avoid tinted covers and chunky frames; pick ultra-thin solutions that cover nothing.

  2. Mounting in areas other than intended
    Moving the plate to a “cooler” spot may violate the obligation to use the designed supports. On honeycomb grilles, clamp from behind using blocks/extenders to stay correct without drilling the bumper.

  3. Angles/curvature that distort the plate
    Bent or over-tilted plates create glare/shadow → poor readability. Keep the plate perfectly flat and use a millimetric alignment accessory for tricky bumpers/grilles (e.g., SleemFix).

  4. Dirt, ice, films
    Law treats unreadable plates due to dirt/ice or the use of films/covers as sanctionable. Clean regularly and avoid any “overlay” that may distort visibility.

  5. Damaged / non-compliant plates
    Severe bends, cracks or unapproved fonts carry risk of sanction. Replace the plate through official channels; don’t attempt DIY “retouching.”

  6. Missing one of the plates
    Driving without both plates in their intended positions is prohibited. Re-check fastening after washes/impacts; with a modern magnet-to-magnet layout you can perform a quick static pull test at both lateral points.

FAQ

Are magnetic holders legal?
Yes - provided the plate is securely fixed in the manufacturer’s intended positions and stays clearly visible. The law doesn’t dictate the method; it requires proper placement and readability.

Can I use a frame or a “clear” cover?
Yes, only if it doesn’t cover any part of the plate and doesn’t impair readability. Avoid tinted/reflective caps that may be considered devices hindering legibility.

Is there a single EU rule for plate position?
Positioning is defined nationally; at EU level the country sign (blue band) is recognised. International principles require both the registration number and the state sign to be clearly visible.
