Dear Mary | 28 May 2011
Q. I thought I was au fait with road users’ etiquette, but confess to being nonplussed when confronted by the advisory signs Baby on Board or race horses in transit displayed in vehicles. Mary, what is the correct reaction to this information? Should one hoot? Cheer? Smile sympathetically? Flash the headlights? Pray? Depending on your advice, should one adapt these signs, do you think, to read Headlice on Board when ferrying schoolchildren around? —J.J., Shaftesbury, Dorset A. These signs are not entirely without purpose. They point to a motorist who is either passive-aggressive or lacking in good judgment. Steer a wide course. Q. A rather supercilious middle-aged American lives in the same apartment block.
