There are still no LAWS concerning electric scooters here in Hawaii but anyone riding scooters must obey the bike lane rules in Waikiki... OUTSIDE of Waikiki, the cops do not care where you ride.
On Kalakaua ave in Waikiki, you must ride in the direction of traffic ( one way) , if you do not it's a $40 ticket.
Ala Wai, must ride in the direction of the traffic, a $40 ticket.
DO NOT RIDE ON THE SIDEWALK IN WAIKIKI. $40 ticket. ALL COPS IN WAIKIKI ARE ROOKIES AND WILL GIVE YOU A TICKET... that's all they do.. write tickets.
Have fun and be safe. Tons of vehicles and the rental cars are the worst... they make a right turn without looking and i crashed into one... idiots !!
