so if you hold a block of wood while driving, can you be ticketed for using a block of wood while driving? What if you plug headphones into a block of wood that is sitting in the seat next to you?

Driving while using a block of wood isn't illegal though.

Could the block of wood be considered a communication device if you write on it to communicate with your passengers?
