“I had so many things going on inside my head . I thought have I failed my test? Has the deer died? It was crazy when it happened.”
Mr Lo was told to pull over while the examiner checked the vehicle for damage before he was allowed to continue the test.
He added: “I was pleased to pass my test but I also killed a baby deer so I didn’t feel like celebrating. I was just happy because I had worked hard and it was important to me.”
His instructor Robert Jezierski, 56, of Coggeshall Driving School, said it was obvious the teenager was “shaken up” when he returned to the test centre.
He said: “Whenever someone passes I usually get a smile or the thumbs up but Tom was just sat there you could tell he was shook up.
"Full credit to him though because it didn’t affect his driving and he passed with only two minors. I think he was just happy to get it out of the way with the exams coming up.”
