A truckside advertisement or truckside ad is a billboard that is affixed to a truck that is for the purpose of advertising to the general public. This is a form of outdoor advertising classified as transit advertising by the outdoor advertising association of America.[1]
Truckside advertisements have been argued by many to have one of the lowest CPM (Cost Per Thousand) impressions available to advertisers in the market.[2] with a cost coming in at 81 cents per thousand compared to 10.40 for a 30-second TV commercial on a prime-time network, 11.03 for a quarter page newspaper ad, and 9.14 for a four-color magazine ad.[3]
