It can happen in the blink of an eye.

Mohamed Yusuf was driving to work on the 417 around 2:30 a.m. Friday, September 30, when a deer jumped in front of his car without warning.

"It just ran across the highway. It was instantaneous, like bam," Yusuf said.

Yusuf said he was doing everything right before the crash happened: driving the speed limit, scanning the road for other vehicles and staying a safe distance from the car in front of him.

“You can see from the video that there is no way I could have prevented it,” Yusuf said. 

Experts say October and November are two of the worst months for deer-vehicle collisions because of the shorter days and season changes. 

To stay safe, the city of Ottawa said drivers should reduce their speed, use high beams when possible, and to slow down when coming up to a curve or hill. If you do hit an animal on the road, you are advised to pull over, call the police and shine your headlights on the animal so other drivers know it is there.
