Is the sign for 'freeway' the same as 'highway'?
Yes, in ASL, the same sign is typically used for both 'freeway' and 'highway'. The context of your conversation will usually make it clear which specific type of major road you are referring to.
Can I use the sign for 'street' instead?
While people might understand your general meaning, 'street' or 'road' uses flat hands and a parallel forward motion. 'Freeway' specifically uses the alternating 'U' handshapes to show high-speed, multi-lane traffic, so it is best to use the exact sign for clarity.
How fast should I move my hands?
You can adjust the speed of the alternating motion to match the context. A smooth, moderate pace is standard, but signing it faster can imply speeding traffic, while signing it slowly might imply a traffic jam.
