  • Seat belt wearing in other Chinese cities
    Virginia H Routley

    The article documenting the successful seat belt intervention and attributable increase in wearing in Guanghzhou, China is a substantial contribution to road safety in middle-income and low-income countries. The reported increase in seat belt wearing is particularly significant in the context of documented declines over 3 years (2005-2007) in two other eastern seaboard Chinese cities, Nanjing, Jiangsu Province and Zhousha...

  • Support for Research
    Joseph M. Fleming

    Dear Editor

    First I want to thank the authors for an excellent study. As the authors discuss, the benefit of using photoelectric technology to reduce smoke alarm disablement and thereby fire deaths has never been adequately communicated to the public. (Note: This author has made repeated requests, accompanied by extensive research, to the National Fire Protection Association (NFPA), Underwriters Laboratories...

  • Zero Blood Alcohol (BAC) Limit for Drivers Under 21 - Authors response
    Erika Chamberlain

    Dear Editor,

    We are grateful for the letter of Desapriya et al. regarding our recent Special Feature, and agree with the sentiments it expresses. We, too, view our proposal to extend BAC limits to the age of 21 as part of a much larger initiative to reduce traffic crashes among youth. Indeed, we outlined a more comprehensive approach to the issue in our 2006 report, Youth and Impaired Driving in Canada: Oppor...

  • Side flag
    Tom Trottier

    Dear Editor

    One strategy to increase the bubble around you is to put a side flag on your passing side. Drivers then give you more room. EG, see http://www.bikecommuters.com/2007/08/18/d-tour-bicycle-safety-flag-first- impression/

  • Zero Blood Alcohol Concentration (BAC) Limit for drivers under 21
    Ediriweera Desapriya

    Dear Editor

    It is timely that Chamberlain and Solomon [1] are proposing an extended zero blood alcohol limit for young drivers and it will definitely save more young lives; however, we believe that drinking and driving is an important part of this complex problem and we have to streamline all other Graduated Driver Licensing (GDL) components in order to realize the significant impact of GDL in saving our children in...

  • Cycling in New Zealand
    Peter J Morgan

    Dear Editor

    My wife and I spent a couple of months cycling in the South Island last year. Apart from some cycling-friendly towns (eg Nelson, Wanaka) it was in general a terrifying and oppressive experience. Even on relatively quiet roads, overtaking traffic would often scrape past us in spite of our obvious visibility and bulk (because of our loads) and relative instability. Following traffic unable to overtake w...

  • Legislation against alcohol-imparied driving in Japan
    Shinji Nakahara

    Dear Editor

    Nagata et al. reported effectiveness of Japanese law against alcohol-impaired driving, which would serve as a useful reference to other countries.[1] However, for this paper to be really helpful to policy makers, the description of legislation should be accurate; and changes other than the road traffic law, which might have influenced the results, should also be described.

    The authors sta...

  • Re: High-conspicuity aids and motorists' perception of cyclists' motion and distance
    Tom Trottier

    Dear Editor

    The original study considered fluorescent clothing which stands out with bright unusual colours. The background matters less, so long as it does not consist of other bright unusual colours. It would be interesting if the original data considered where the fluorescent cyclists had collisions. I expect that they were more at risk along commercial streets than residential ones because of the many commerc...

  • High-conspicuity aids and motorists' perception of cyclists' motion and distance
    Tony H. Reinhardt-Rutland

    Dear Editor

    As Thornley et al [1] indicate, the use of high-conspicuity aids by cyclists must be beneficial: motorists can only avoid collision with the cyclist if they can detect the cyclist.

    Unfortunately, high-conspicuity aids are not likely to affect the visibility of the roadway environment around the cyclist, so motorists' perceptions of the cyclist's motion and distance will remain poor in condi...

  • Worldwide helmet concerns
    Colin F Clarke

    Dear Editor

    The article by Macpherson et al[1] relies on surveys from 111 sites around East York (Toronto) and some questions remain about these surveys. Data from two reports provides confusing indications on the level of cycling. In 2001[2] figures were published for the hourly rate for several years and by comparison in 2003[3] counts for 8-years were provided based on 1 hour observation at each site. An hourly rate...
