Thanks for the entries.
#46 too many lines especially with line unledrlining safety makes logo too busy
Between #45 and #46 then #45 is the better color, more authoritative
Just in case you are geeting confused with the Swedish ....
Safety is not the same as Security (therefore there are no layers of safety) therefore relevance of symbol is vague.
Safety when related to a car is normall braking system, air bags, cruise control etc which are all controlled by software. Safety in automotive is also often associated with speed, therefore speedometers are also used.
Safety normally has to be assessed - hence tick mark on other logos.
Hope this helps
