The survey interviews recorded a reason or purpose for each trip as well as describing the trip's origin and destination and detailing time of day and travel mode (driving, walking etc).
The reasons were broadly classed as: going home, going to work, work-related trip (employer's business), education, shopping, etc. The following pie charts show how distance driven was divided among the various reasons for the trip.
Trips made with the purpose of going home are not included because trips with this purpose are simply trips returning from doing something else. Trips made with the purpose work refer to commuting trips from home to workplace.
Likewise, education refers to trips commuting from home to school, university, etc*. The chart here shows that commuting (between home and workplace or education institution) makes up 17 percent of all driving distance. Social and recreational trips make up the largest proportion (32 percent) of all driving.
The pattern changes with age. For drivers aged 65 and over (see chart), almost half (47 percent) of all driving is for social or recreational reasons. Shopping accounts for a further 22 percent.
*A certain small proportion of trips 'to accompany someone' will include trips made by a relative or a friend driving a child to school, for example.
