For Delivery Vans it is pretty much crucial to have some kind of Van Signage, even if it is just some simple Van Lettering. Not only do you install faith with your customer, but you also have an unusually high chance of reaching your target audience. People tend to group together with like-minded people (in personal live and business), so when you deliver your goods you have a prime opportunity to spread your advertising message directly to your target audience who can see their peers using and approving your product or service on the spot which is rare in advertising.
