As a mobile billboard, your responsibilities are to drive a vehicle on a specific route to advertise a company, promote a product, or fulfill another marketing purpose. Companies or marketing agencies hire mobile billboard drivers to drive vehicles with advertising, usually in the form of vinyl wrappings, stickers, or large boards you carry on a car, truck, or bike, for mobile promotion. You have a set number of hours and a route to follow each week or month to carry out your duties for the company. These can be either employment or contract positions, and in some cases, you can do this job while working another position, such as food delivery or rideshare.
