Sounds like they charged her incorrectly, hitting her for driving “10 mph or more below the speed limit” when she was only doing 2mph under.
If she was blocking traffic, and they charged her with obstructing traffic, that would make more sense. Assuming she was actually blocking traffic.
Generally I think that law should be applied if some idiot in the left lane decides to pace the other cars in the center and right lanes to create a rolling blockade. I’ve been behind people like that before, they think it is their job to keep the rest of us from speeding.
I think we should allow people to go much faster if they like, and then have fines for accidents based on speed over the “recommended” limit.
So, instead of a speed limit of 65, they could have a “recommended limit 55, max 85”; if you are going 85 and have an accident, they charge you $1000 and suspend your license.
That way, we get to punish people who actually cause harm, while not restricting everybody’s liberty because of some lowest common denominator of unskilled drivers.
And the relatives of the family of four that was killed will just have to get over it.
Worst sin you can commit on Washington area highways is to make them clog up more than normal.
