Not bad for such a short story. The sentence where you turn on the headlights and the cemetery entrance is right in front of you is awesome! I didn't expect that.
I did find a few typos:
It is raining heavily and [I'm] fearing the traffic jam, [so] I take a diversion of[f] the main road.
The following sentence is hard to imagine if it's raining so hard:
I chuckle, as I gleefully speed ahead for a mile or two.
The words 'has' doesn't need to be in this sentence. It changes the tense of the sentence:
The rain has eased off but the wind speed has suddenly increased.
It reads better as:
The rain eased off[,] but the wind speed suddenly increased.
Your last sentence is classic! It would easy to continue this story, but don't do it! I end my horror stories the same way. Leave them hanging in the wind...LOL!!!
