Photograph all of your vehicle VINs for insurance proof of ownership and ease of claims. Include all trucks, cars, vans, delivery trucks, trailers, tankers and any licensed road vehicle covered by your automotive insuranc policy. File these away in case you need to file insurance claims or police reports or compare conditions of your vehicles between assigned drivers. Assign the drivers to shoot and send forward pictures of those vehicles and their corresponding vehicle serial numbers normally found on the top of the dashboard.
