Vehicle, Truck, and Trailer Signs
This type of sign can be for trucks, and tractor-trailers all the way to a 6" sign on a bicycle. It can be permanent, semi-permanent, temporary, or removable (magnetic) so you can use it when you want to.
The best and longest-lasting is to mask the vehicle and paint the sign with proper automotive paints and clear coats. Almost no one does that anymore, it's too expensive, and when you want to sell the vehicle it can't be removed, reducing the resale value.
Vinyl is the best option for most It can be warranted for up to 8 years with a longer life expectancy than that and it can be removed later if required.
Digital prints and wraps are only warranted for 3-4 years and can be very expensive, I'm not saying they're no good but for many, the cost is too much.
The first wrap you ever saw you stared at and studied because it was so new. How many do you look at today? So many wraps are so complex (graphically speaking ) that you see them but have no idea what they are promoting, I have seen some that as I followed through traffic I tried to see what it was advertising and I never did find out, someone spent $2-3,000 and wasted their money. There are some rules of signage and the use of color that shouldn't ever be taken lightly. 
Better to keep it simple, What you do is very important for most businesses or trades even more so than your name to start with. Then contact information, logos are important if you have several vehicles and you want brand recognition, but not essential. Put yourself in the position of a customer. How often do you look for just a logo when you are looking for a new supplier? Remember signs are for those folks who have never read your sign before, after that it will be ignored. Vehicle signage is probably the cheapest and best advertising you will ever find, and yet it's only for folks who have never seen you before. They'll be subconsciously asking a few questions during those short, precious seconds it takes for them to see your truck. Here's what they are:
What do they do?
Do they work in my area?
How do I get in touch with them?
What's their name?
My, what a nice logo!
Give them all that and you have new customers.
