What does a diamond sign showing a person walking warn of?: A pedestrian crosswalk; This sign tells you there is a crosswalk ahead. Watch both sides of the street for people and be ready to stop for anyone in the crosswalk. (Rules of the Road, p. 68.)
Why does a crosswalk sign sometimes have a flashing yellow beacon?: To warn that people may be crossing; A flashing yellow beacon on a crosswalk sign makes drivers more aware of the crosswalk and that pedestrians may be in it. Slow down and be ready to stop. (Rules of the Road, p. 68.)
Crosswalks are always at intersections. True or false?: False, some are mid-block; Crosswalks are not always at intersections, so watch both sides of the street for pedestrians when you see a crosswalk sign. (Rules of the Road, p. 68.)
Who often supervises school crossings when students go to and from school?: Crossing guards or police; Adult school crossing guards, auxiliary police or police officers often supervise school crossings, sometimes helped by student safety patrols. Obey their directions, slow down and stop when needed. (Rules of the Road, p. 69.)
In a posted reduced-speed school zone, when does the lower speed limit apply?: School days with children present; The posted school speed applies on school days when children are present, usually from 6:30 a.m. to 4 p.m., though hours may vary, or when a light is flashing. (Rules of the Road, p. 69, 24.)
May you use a cellphone while driving in a posted school speed zone?: No, it is prohibited; Using a wireless phone is prohibited while driving in a posted school speed zone. Put the phone away before you enter the zone. (Rules of the Road, p. 69, 25.)

Why are advance warning signs like SIGNAL AHEAD also used in high-speed areas?: You need more distance to stop; Advance warning signs are used in high-speed areas because a vehicle needs a longer distance to slow down or stop. (Rules of the Road, p. 69.)

A lane reduction sign shows one lane ending. What should you be ready to do?

Change lanes or let others merge

Lane reduction signs warn that the number of lanes will drop. Be prepared to change lanes or let other vehicles merge into your lane, and adjust your speed and position to avoid a crash. (Rules of the Road, p. 71.)
Traffic is congested and two lanes become one. What does the manual advise?
