Is there a rule about walking in a crosswalk with a flashing red hand and the seconds ticking down?

Once the "don't walk" symbol begins to flash, it is no longer lawful to leave the curb and begin crossing. After the flashing "don't walk," a solid "don't walk" is displayed on the signal at the same time the traffic signal turns amber for vehicles. The transportation department figures the amber light should be long enough for vehicles to clear the intersection, or for motorists to complete a turn without competing with pedestrians in a crosswalk.
