OK to show a meaning of 'when' using participles?

Driving, I can talk to others. 1st
I.e. I can talk to others because I drive
- "Driving" is a present participle which tells the reason

I can talk to others driving. 2nd
Sorry, I don't know what it means

When driving, I can talk to others. 3rd
Correct.

I can talk to others when driving. 4th
Correct, means the same as the 3rd one.

好顯示'when' 的意思; 使用分詞?
駕駛, 我能與其他人談話。第1
我能與其他人談話駕駛。第2
當駕駛, 我能與其他人談話。第3
我能與其他人談話當駕駛。第4

Pls 告訴我哪個句子是正確的如果我想要說' 那時 我是駕駛,
謝謝!
