It is not permissible for someone

Q 3: There is someone who works as mail deliverer. He travels very long distances in his car, around 700 km daily. What is the ruling on his Salah (Prayer)? Can he combine the Salah?

A: If the distance he travels is inside the same city and traveling from one district to another, he cannot not shorten the four-Rak`ah Salah (Prayer consisting of four units) or combine Zhuhr (Noon) and `Asr (Afternoon) Prayers or Maghrib (Sunset) and `Isha' (Night) Prayers, because he is not considered as a traveler. However, if this distance is in between two cities or countries, (Part No. 8; Page No. 109) for example, it is permissible for him to combine and shorten Salah, because he will then be considered as a traveler and will be eligible for the Rukhsah (concession) of travel.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
