Examples

If I go to school, I get up at seven.
If you park your car on double yellow lines, you pay a fine.
Bill always helps me if I ask him.

The zero conditional describes situations that are always true. If has the same meaning as when, whenever. Compare the examples of the zero conditional sentences above with the following sentences:

Whenever I go to school I get up at the same time.
Whenever you park illegally, you pay a fine.
Bill helps me whenever I ask him.

We use the present simple tense in both the main clause and the if clause.

Other forms

Apart from the present simple in the main clause and if clause, we can use other verb forms in the zero conditional sentences.
Examples:
If you want to be fit, you must exercise. (a modal verb in the main clause)
If you are tired all day long, sleep more. (an imperative in the main clause)

Note

If is the most frequent expression in the if clauses, but other expressions are also possible: even if, provided (that), unless, on condition (that).
John always shouts even if there's no need.
Meet goes off provided that you don't keep it in a fridge.
Iron melts on condition that it is heated.
Jane never says hello unless you say hello to her first.
