At most carnivals that I attend I will take some time to locate the cars, trucks and motorbikes that are at these events. There is usually a good appearance of these machines that are made my mankind. They have shapes and patterns which allow you to see the difference.
Some vehicles follow a uniform design to allow you to understand their importance as shown below.
Due to road closures for events most cars cannot get through unless permitted. Motorbikes can get through these closures and gather in one place so that you can capture a picture of them.
In Jamaica I attended the Carnival on the 28th April 2019 in Kingston and captured quite a lot of images of motorbikes, one truck and a few cars. Here are the vehicles in their wonderful colours.
The image below is a back of a car mirror showing me sitting at a bus stop.
