Using the Causative

Note that one of the duties that the Causative Verb form carries out is to make intransitive verbs (verbs that do not take an object) into a transitive verb (verbs that do take an object).
The verb - durmak - to stop/to halt - is such a word:
Araba caddede durdu - The car stopped in the street. - (No object in this sentence - it is intransitive)
Mehmet, arabayı caddede durdurdu - Mehmet stopped the car in the street. - (The object in this sentence is arabyı - the car - it is a transitive sentence)

English may use a different verb for its causative form

The translation of the Causative is literal here. We have to consider that in translation we may use a different verb in English. If we look at the first example, the Causative of - to know - has been literally translated as - "to make know, to cause to know" - of course we may translate this verb into English as - to notify, to publish, etc.. We must always bear this in mind when translating Causative Verbs from Turkish into English.
