The route a Company vehicle may take on a recurring basis will have an affect on the type of sign that should be applied.
For example, if the travel patterns include more Interstate driving that in town driving, one can conclude that potential viewing time for the sign will be greatly diminished. The opposite would apply for in town driving. If city driving will be the norm, the average viewing time for vehicle sign will be greater. Interstate driving factors would insist that a vehicle sign be much simpler for easier viewing, while in town driving is more forgiving allowing for more complicated signage to be present.
