When travelling in a vehicle, bicycle and others

Say three times:

اللَّهُ أَكْبَرُ

then say:

سُبْحَانَ الَّذِي سَخَّرَ لَنَا هَذَا وَمَا كُنَّا لَهُ مُقْرِنِينَ وَإِنَّا إِلَى رَبِّنَا لَمُنْقَلِبُونَ

– Surah 43, Verse 13

Make it a habit and you will always be safe from an accident, InshaAllah.
