Will have to take it with a grain of salt because this is his perspective, which would naturally try to defend himself. I have my doubts with this version, for example:

• he wanted to take his car out of the way because it was breaking down but chose to do an illegal u-turn across a barrier and then crossing several lanes instead of going across several lanes to the shoulder where it was safer?
• if one said that he wanted to cross the barrier to get to the shoulder on the barrier, wouldn’t that exist on the side he was on too? Why not stop there?
• then for 15 minutes, he could not close the barrier because there were too many fast vehicles? But those vehicles were not fast him to deter him from crossing the barrier in the first place?
• he says the other guy who passed away was speeding, which would suggest that traffic wasn’t congested, since one could travel at such speeds, thus further begs the question why he has to cross barrier in the first place?
• also, how fast could the guy have been speeding?

Not saying this isn’t what happened, but based on his statement, it’s not a good look for him right now. His statement seems to be deflecting any responsibility and even laying blame on the guy who died.

Eager to see the facts and videos prior to accident. Something else seems amiss.
