Поехать is the most generic perfective verb that means “to go by vehicle.” Note especially its irregular future and imperative forms.

Поехать is more specialized than ездить in that it always talks about motion in one particular direction; since it is perfective it also focuses on some result of the action:

In that sentence, the result is that I arrived at the square and thus could view the body.

Поехать can also be used to describe each leg of a multileg journey:

Of course you can do the same thing in the future tense:

Now here's something amusing... let's think about this English dialog:

Does the second sentence imply that Mom got to the farmers market? No, it doesn't. Here it emphasizes absence from the point of departure while mentioning her intended destination. Likewise in Russian a perfective verb of motion can be used with meaning of “absence from point of departure”:

The sentence does not say where Mom has necessarily reached the market, just that she is no longer here.

¹ All three of those places are suburbs of Moscow that you can reach on the электричка on the way to Tula.

Ехать is the determinate (unidirectional) form of the verb ездить “to go by vehicle.” Note especially the odd д that shows up in the present tense forms, as well as its curious command form.

Ехать is more specialized than ездить in that it always talks about motion in progress toward a particular place. Let's say you bump into a friend on the subway. Because you are in a vehicle, you can say:

Although normally adverbs of frequency and phrases of frequency (like часто and каждый день) usually trigger an indeterminate verb, if the situation describes something that happens regularly on the way to a place, then you use the determinate verb ехать:

One of the curious uses of determinate verbs is that they can be used to say how long it takes to get to a place. From the English-speaking point of view that is rather odd. After all, getting to the place implies a completed action, so we should use a perfective verb, right? But from the Russian point of view in these sentences they are indicating how long the process takes, so the imperfective works:

The word нуль sometimes occurs in fixed phrases like «начать с нуля» “to start from zero,” which catches the idea of beginning a process with zero previous knowledge or experience or resources:

Just as in English you can refer to someone as being a complete zero (i.e., being a worthless human being), so also the Russian word can be used in that sense:

The word is also used to describe a certain haircut «под нуль», that is, “down to zero” or bald. It's the haircut that every draftee receives when joining the Russian army.

Как только пойдёшь в солдаты, тебя остригут под нуль.
As soon as you become a soldier, they shave you bald.

The haircut has become so popular among tough young men that sometimes they are called нули, which is probably best translated as ‘thugs.’ (You can hear the word used that way in the elusively connected song «Главное» “The important thing” by the singer Земфира.)

Ездить is the most generic word in Russian that means “to go by vehicle.”

Although we often say the verb addresses motion by vehicle, it's actually broader that that. It covers travel on animals (horse, donkey, camel, etc.), bicycle or motorcycle or scooter, and by the typical wheeled conveyances like train, bus, car and truck. In addition to the “go” translations, words like “ride” and “drive” are also suitable:

The verb is also used to describe the driving around a locale with no set direction, e.g., driving around an area for sight-seeing, or going here and there to shop. In this meaning the verb is complemented by the preposition по with the dative case:

Last but not least, the verb is used to indicate a single completed trip in the past. In this usage it implies that the person is no longer at the place mentioned.

Russian has two words for zero, and they are ноль and нуль. For most purposes they are completely interchangeable and decline like this:

You will most encounter these words is when reading phone numbers out loud. In the US one usually reads phone numbers out loud digit by digit:

In Russia they usually break up a seven-digit number into groups of 3-2-2, and you say ноль only when the zero is the first unit in a group of two or three digits, thus:

(The first zero is pronounced as ноль, and the second zero is understood as part of девяносто.)

In the US most people do not refer to the time of day using the twenty-four hour clock (“military time”) unless they have served in the military or are engaged in precise time-keeping functions, but in Russia all official schedules are posted in twenty-four time, so the phrase «ноль часов ноль минут», which means literally “zero hours zero minutes” and can be translated “oh zero hundred” in military parlance, sounds perfectly normal to an average Russian. You can even hear the phrase in the song «В ноль часов и ноль минут» “At midnight,” which is a cute little tune about how hard it is as a child to stay awake all the way till midnight on New Year's Eve. Click the title of the song just above to hear it. Do listen to it. It's charming.
