“fart” is colloquial swedish for speed, but the actual meaning (as used on signage) is “travel” or “fare”, like german “fahr-” words. so we have “sjöfart” (seafaring), “rymdfart” (space travel), “fartvind” (wind rushing by when moving quickly), “uppfart” (driveway) and, importantly for signs, “utfart” and “infart” (exit and entry for vehicles).

my favorite of this is a sign nearby on a narrow road that warns about multiple exits with no sight lines.
