In fact a study was conducted in Australia where it was found that 90%of drivers notice car signs and 75% among them form an impression of the company based on the sign. Car signs tell viewers a lot about a business. The right signage prompts more web hits, more phone calls, more site traffic and more sales opportunities. In a year, a car’s signage acquires millions of impressions at a CPT, that’s far less than stationery billboards, newspaper ads and other forms of advertisement.
Consistency is also another factor that is considered. If people see the same message on all the cars like they see on building signage, print advertising, billboards and web, there occurs continuity in seeing the message from various channels. This goes a long way in establishing a brand.
