Can I use this sign for riding a horse or a bicycle?
No, this specific sign is used for riding in a vehicle like a car, truck, or bus. For a horse or bicycle, you would use a different sign where your dominant fingers straddle your non-dominant hand to mimic sitting on a saddle.
Does the direction I move my hands matter?
Yes! You can change the direction of the movement to show where the ride is going. Moving it forward means riding away or traveling, while moving it toward yourself means someone is giving you a ride.
Should my base hand be open or closed?
Your non-dominant base hand should form a 'C' shape, almost like you are holding a cup sideways. It shouldn't be completely closed into a fist or completely flat, as it represents the vessel you are riding in.
