What exactly does 车管所 mean?

车管所 means the vehicle administration office or motor vehicle bureau. It is where people handle things like:

• vehicle registration
• license plates
• driver’s license paperwork
• ownership transfers

It is short for 车辆管理所. In everyday Chinese, people often use the shorter 车管所.

Why is 正在 used here?

正在 shows that an action is in progress right now.

So:

• 车管所正在审核我的申请材料。 = The vehicle administration office is currently reviewing my application materials.

It is similar to English is reviewing.

A useful comparison:

• 审核我的申请材料 = review my application materials
• 正在审核我的申请材料 = be reviewing my application materials right now

Can I say the sentence without 正在?

Yes.

• 车管所审核我的申请材料。

This is grammatically fine, but it sounds less clearly focused on the ongoing action. It could sound more like a general statement, depending on context.

Using 正在 makes it clear that the review is happening at this moment or during the current period.
