To determine whether a word is countable or non-countable, we consider whether the word can be quantified or not.

1. Traffic: Traffic is considered a non-countable word. It refers to the general movement of vehicles on the road and is not quantifiable. We don't say "one traffic" or "two traffics." However, we can use words like "heavy," "light," "bad," or "smooth" to describe traffic. For example, we say "There is heavy traffic on the road."

2. Highway: Highway is a countable word. It refers to a major road that connects different places and is quantifiable. We can refer to multiple highways as "highways" or use numbers to specify them. For example, we can say "There are three highways near my house."

Remember, countable nouns can be used with a plural form and can be preceded by numbers or words like "a," "an," and "some." Non-countable nouns, on the other hand, cannot be pluralized and are not used with numbers or articles.
