What measures should drivers take to avoid texting while driving?

The main reason is that the law is strict, so it is easy to solve the problem by checking the situation of driving and making phone calls like drunk driving.

If you are a driver and have an important call, can you answer it with headphones or ask someone in the same car to answer it for you?

Driving without calling is mainly for everyone's safety.

I usually stop to answer the phone. If it's an unimportant call, you can call back later.
