If your driver is a 33-year-old woman you can sit back, relax and enjoy the ride. Statistically, women drivers in their late twenties and early thirties are the safest on the roads and at their absolute safest aged 33. There are four fatalities among 33-year-old women for every billion kilometres driven.
That compares with 40 fatalities among 20-year-old males for every billion kilometres. Researchers at the University of Calgary, Canada, studied accident data that showed male drivers are at their safest between 33 and 54 — fewer than eight drivers of those ages were killed yearly per billion kilometres.
The over-eighties had the highest fatality rate of any age group, for men or women, but the study claims the statistics are distorted by the small number and low mileage of older drivers.
