KEY HIGHLIGHTS:

  • Night driving self-restriction patterns (assessed by questionnaire) were examined cross sectionally in relation to age, gender, health and cognitive status, depression, and vision function in a sample of 900 elders (mean age, 76 years) living in Marin County, California.

  • Of the total sample, 91% of men and 77% of women were current drivers.

  • Among current drivers, women had slightly better vision function than men on most measures (low-contrast acuity, contrast sensitivity, low-contrast acuity in glare, low-contrast, low-luminance acuity, and glare recovery) but were twice as likely as men to restrict their driving to daytime.
