All of the following apply to proper placard placement EXCEPT:

Placards must appear on both sides and ends of the vehicle. Each placard must be:
- Easily seen from the direction it faces.
- Placed so the words or numbers are level and read from left to right.
- At least 3 inches away from any other markings.
- Kept clear of attachments or devices such as ladders, doors and tarpaulins.
- Kept clean and undamaged so that the color, format and message are easily seen.
