No. 3 (51/2" × 31/4") "Well, it was a sad business," says Policeman 101. "Van driver lost control coming down a hill and crashed into a school girl. Of course, she ought to have been keeping a better look-out. But if those brakes had only been checked before the van started, the accident might never have happened." ¶ A little extra trouble may "My brakes let me down on the hill" mean the difference between life and death. This is especi- ally true just now. Surfaces are war-worn. Traffic is heavier, and many pedestrians and children are unused to it.
