Swedish: Å Ä Ö

Denmark: æ ø → Denmark.

Norway: æ ø + yellow middle lines → Norway.

Iceland: þ ð → Iceland.

Wooden poles w/ small black metal cap on top (Nordic-only); lamps mounted slightly below the top w/ double bolting (Finland: top-mounted, straighter); wooden electricity markers w/ blue+white stripe = Sweden-only in the Nordics

The blue-white electricity markers exist in no other Nordic country; the pole cap is pan-Nordic.

Norway: Norwegian M + yellow lines → Norway.

Chevrons yellow arrows on blue - only country in Europe (very rare in Luxembourg); much infra painted red+yellow (roadwork signs, blocks, even chevrons); signpost stripes: blue-white (also FI/EE) but red-yellow/blue-red/white-red ≈ Sweden-only

Yellow-on-blue chevrons: only Sweden (Luxembourg has ultra-rare ones). The red-yellow infra scheme is the fastest Sweden tell.

Luxembourg: Red-yellow painted infrastructure (roadwork, blocks) → Sweden; Luxembourg lacks that scheme entirely.

Street suffixes -vägen / -gatan (short v/g; gränd near centres); Norway: veien/gate attached; Denmark: vej/gade
