Come "to" or "at" an intersection

[Abecedarian]

Which of the two is correct and why

As I was driving I came at an intersection and decided to turn left
or
As I was driving I came to an intersection and decided to turn left

Also is it right to start the sentence with "As I was driving." Is there a better way to start the sentence with but convey the same meaning?.

Thanks very much

My guess is gonna be " come to" just because the most common use of "come at" is attack somebody.

'To' is a preposition of motion, and 'come' is a verb of motion-- 'I came to school', 'I came to my senses'.

'At' is a preposition of location, and is used with stative verbs-- 'I sat at the station', 'I arrived at the airport'.

'As I was driving' is fine, but perhaps redundant.

Yes, those are right, ABCDarian. Any good grammar book should have a section on the types of prepositions; you can also google for them, and come up with such sites as THIS ONE. (I called them 'prepositions of motion', but here they are called 'prepositions of direction'.)
