Estes SureMove

As I was coming onto the interstate I was ahead of him I just needed to merge into traffic. As I was beginning to merge this truck sped up to keep me from getting in front of him... I ended up driving along side the truck on the edge of the road till I could get behind him. This happened in Illinoiis on May 22 2019 at approx. 445 pm. I underatand that traffic does not have to move over but what he did was dangerous. Coming off a ramp the driver needs to pick up speed to merge into traffic... i had a vehicle behind me as well... I couldnt slam on my brakes or that car would have hit me... luckily I didn't flip my car... that may have cause me or my grandson to be hurt...
