What are the type attributes

We should label more than 2 clearance spots per truck

Labeling Streetlights=blank when you can see streetlights far away in the background but unsure if it's on our road.

What's under Invalid for marking?

This is used for us to identify if we encountered an error after labeling a specific clip

If  main spots of a truck/bus (taillight, oncoming) have no tags on them, then you must label its' clearance spot/s.

Attributes will be applied for a specific tag.

Frame attribute will be applied for a specific frame.

If you can identify a spot through another vehicle's windshield or through a mirror, you still need to label it and take it under consideration when labeling "vehicleExists" frame attribute.

Choosing to Label fog light when there are unlabeled tags on the main spots in the frame
