yes, there may be initial confusion about the blinking yellow lights.

but believe me - it is a relief for the busy drivers

GREEN - You can pass the roundabout...the vehicles
coming from the left side of the roundabut will
stop for you
and you can drive

RED - You are NOT supposed to drive. EVEN IF THERE
ARE NO VEHICLES coming from the left side.

YELLOW - You are allowed to drive , ONLY IF, there are no
vehicles coming from the left side of roundabout

I think it is a wise step
