Street, Path, Way
Aim the scooter's neck at the road! Scooters are only meant for driving on streets and paths, and if you go the wrong way, you'll probably break your own neck!
To remember the reading どう we use the word "doughnut."
You're traveling down this road so fast that you don't see the giant doughnut (どう) that's rolling toward you until the last minute. You crash into it, and both you and the doughnut go tumbling down. Ahg, your neck!
