re: BR Officer arrested for DWI after possible involvement in traffic accident

I agree. The article doesn't make things very clear. We have to deduce:

There was some(possibly minor) collision between the cars. Hers lost control. He pulled over and helped. He was intoxicated.

Questions:

Did the cars actually hit or did he just swerve in her lane? Did his intoxication play a role? As in, maybe she went into his lane and caused the initial collision.
