overdue signage at North Capitol and Rhode Island Avenue

See this tweet:

Have you seen the long-overdue signs at RI & North Cap, warning cars they prob. have to stop after turning into RI Ave?
Me & everyone else have had so many close calls there due to turning cars. Are the signs helping a bit, @EckingtonCivic @bloomingdame @BloomingdaleCA ? pic.twitter.com/bDKuCTEVsE
