Passports and Mexican border?

Question

Is there a lot of time delay (more than usual) coming across the border by car?

Answer 1

I suppose ther are busy times in the morning and evening, but when I crossed there mid-morning, there was no delay.  You do not need a passport if crossing by LAND, but if you have one, just have it in your hand to show.  Otherwise, have your I.d. nd birth certificate ready.

Answer 2

It will help if you specify which border?
