To import a vehicle and to be able to put the plates on it and use it on a daily basis, you need to meet the CMVSS standards. These vehicles do not comply with the CMVSS. These vehicles have different lengths, angles, whatnot, and different security measures that may be equivalent but not exactly the same. So they can't be used on a regular, daily basis. If you were to purchase more than one vehicle, even keeping them one year would not be possible.
But since we're asking for one, two or three buses, depending on the project, we're permitted to keep that bus for the duration of one year. That's a derogation that we're asking for and we have special permission for that.
