I disagree on limits being too low. Higher limits would make the very prevalant tailgating even more dangerous. Limits are just fine if folks got their behinds going earlier in the morning.
With the many antiquated 2 lane roads in Oregon, combined with the mobs of people showing up in this state, alot of these roads are only worth about 45mph instead of the 55 you see so often.
I have avoided a few mishaps already since slowing down on Oregons roads. I noticed many other smart drivers have realized that these roads are safer at lower speeds.
Then brighter lights on todays newer cars... with an oncoming vehicle, much of the time, I cannot see a deer nor a pedestrian on my side so I have to slow down.
Sorry to get so far off topic...
There is a good lesson to be learned from the OP... to look both ways even though the green light says it's your turn to go. Don't make it 'your time to go'.
Life is for living each moment not after you get there.
One final note.... if you look at Oregon accident/ fatality stats you'll find about a third are speed related and about 1/4th are intersection related. The rest are from various other circumstances.
