So the signs are there so that the police have probable cause to stop someone that they otherwise wouldn't have probable cause to stop. Does anyone else see a problem with making otherwise perfectly legal and safe behavior(turning on to a side street) illegal just to legalize an otherwise unconstitutional traffic stop? Seems like another slippery slope we ought not to be sliding down.
I am sure no single old lady will ever be fined or otherwise harrassed by incurring in this violation. This clearly means that law enforcement is using this rule to expand its mandate.
This is just bad legislation.
