To ZD and all others discussing dina demalchusa,
I’m sorry to have to break it to you, but actually dina demalchusa according to most opinions only applies to thing the government raises revenue from, like taxes. It is not a violation of halacha at all to blow a stop sign or red light simply because the law says you can’t.
Of course there is still the halach of venishmartem lenafshoseichem, but in situations where there is no danger (a quiet road in the middle of open country with full 360 degree visibility perhaps?), there is no need to follow such laws.
