Pro tip: no one on the highway has to make room for you to merge.

@jimz1000 If you don't have a yield sign, you're not required to slow down or speed up for anyone. That's unsafe and makes no sense.

Like I said, the only responsibility of someone without a yield sign is to make sure they're not tailgating so other drivers have space to merge.

The laws actually vary by state. But if you won't adjust your speed even a little, cars will have to come to a stop and you're going to have issues, either an accident or an inability to ever merge since now you have to do do from a stopped position. I don't know where you drive that people don't tailgate, but where I live you are forced to either speed up or slow down dramatically to find a spot and avoid getting rear-ended by the car also merging behind you. You and I might avoid tailgating, but that just means someone else will cut over and take that space. The merging car needs to figure out if their position requires them to speed up or slow down as the best option and when they do so, the car they are trying to merge with will likely have to give a tap to their brakes or gas. Speeding up or slowing down to prevent the merger or driving over the speed limit cause you to forfeit the yield in my state.

@jimz1000 Exactly. So just keep your speed and don't tailgate. Then people can merge in front of you. Simple as that.
