The imperative form may also be employed to express a recommendation to do or not to do something, for example if the speaker has a concern that a future event can damage the interlocutor, as in the following sentence.
fe
CL(closed 5): ‘drive_motorbike_fast’ not CL(closed 5): ‘drive_motorbike’ CL(G): ‘speed_raise’ judgement
‘Don’t go fast with your motorbike, drive at the right speed!’
In this sentence as well, the only marker of imperative is the non-manual marking, namely furrowed eyebrows (fe).
