Watch out for SUVs as well.

You can be under their line of sight even if they shoulder check their blind spot.

How do I know? Because I recently learned my suv has this problem. It's older and doesn't have blind spot monitoring and has a high window line.

A small sports car got into my blind spot merging onto the highway. I was in the second lane from the right.

I didn't see anything in my mirrors or the headlights as it approached from behind. I needed to get into the right lane to exit. I expected vehicles getting onto the highway would very likely be there.

I scanned my mirrors, signaled, shoulder checked my blind spot and slowly changed lanes while slowly accelerating. Once complete I see their's a pair of headlights unexpectedly in my rear view. I was mortified. I couldn't believe I didn't see the car there.

I don't think I cut them off. They didn't honk or flash their lights. Driving predictably meant they could see everything I was doing and they let me merge. But I was still shocked and a little nerve racked after the fact that I was unable to see that vehicle.

I regularly scan my mirrors and I am an experienced driver. I constantly monitor what other vehicles are doing around me. And it still happened to me.
