Truck signs can be used in more than one instance. They could indicate hazardous chemicals or substances being carried on board the truck, or they could indicate the maximum weight load capacity of the particular truck. When the truck is a long vehicle, or makes frequent stops, it is wise to signal this on the rear of the truck, so drivers behind the truck can keep a safe distance and not try to overtake in dangerous areas.
Other items displayed on truck signs are the company name, logo and contact details. Truck signs and vehicle wrapping are a cost-effective and relatively cheap means of advertising, as they provide great exposure on a daily basis, and are moving adverts at all times of the day that the truck is in operation. Even when stationary, truck signs still reach a relatively large crowd for advertising purposes. Sometimes, vehicle wrapping is very eye-catching, especially when the design is colourful and includes graphics.
Truck signs could be outdoor signs displayed in parking areas or in loading and unloading bays in commercial establishments, indicating to the truck driver where they may stop or park. These are made of durable materials which can withstand natural elements.
