Where must registration numbers be displayed on a boat?

Registration numbers must be displayed on the bow of the boat. This requirement ensures that the numbers are easily visible from the front and aids in the identification of the vessel. The bow is the section of the boat that typically faces forward when it is in motion, making it the most practical location for displaying registration information. This visibility is crucial for law enforcement and other boaters who may need to identify the vessel quickly for safety or regulatory purposes.

Displaying the numbers on the bow also aligns with general boating regulations and practices, which are standard across many states, including Illinois. Proper placement helps maintain consistency in boat identification, enhancing safety on the water.

Other locations mentioned, while potentially visible, do not provide the same level of immediate recognition as the bow. It is vital for all boat operators to understand and comply with this requirement to ensure adherence to boating laws.
