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)
-
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). -
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. -
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). -
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)
-
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. -
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. -
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). -
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. -
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.” -
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.
