OP"Participle clause doesn't indicate a specific tense; instead, we should look at the main clause to understand it.
Driving on the highway, one must be careful. (present)
Driving on the highway, he had an accident. (past)
Driving on the highway, you will see a big sign. (future)"
Does the future tense part mean
While you drive on the high way,you will see a big sign.
