How can the safety of drivers be predicted?

February 14, 2020 Lasse Hønsen

It is reported that 80% of accidents and incidents within aviation companies are due to human factors. Safety is at the very heart of every role within the industry; from those on the ground, to those in the sky.  

For those in driving roles, accidents, however small, have significant costs. Therefore, having the ability to identify those in the hiring process who are most likely to behave safely would have a clear benefit.

Our Drivers suite of assessments is a proven tool that offers organizations this ability and we worked with a transport company to help demonstrate this.

Validation studies offer the opportunity not just to design a valuable customized assessment solution for an organization but also demonstrates the predictive utility of an assessment.

The aim of this validation study was to determine whether specific talent assessment results could predict accident rates at the transport company, and to then use that information to identify candidates who would be more likely to have fewer accidents. If so, and those most likely to have fewer accidents were hired, a return on investment in the pre-hire assessment could be calculated and as a consequence they could also reduce their insurance premiums as fewer incidents and better claims statistics makes for a more attractive insurance scenario when going to market with motor fleet insurance.

The study

In a company with around 270 drivers, the number of driver accidents had become an issue.

All the drivers had been recruited using quite typical hiring activities such as application form and interview – but no talent assessment. 

The Drivers suite of assessments which combines specific ability tests and a personality questionnaire were administered to 144 drivers in the organisation and the scores analysed alongside each individual’s accident record. 

A Safety score was created from the assessments which was a combination of scores on particular personality dimensions (e.g. striving for harmony, sociable skills, flexibility and perseverance) and two ability tests scores measuring sense of direction and multi-tasking. 

The results

The standardized scores were converted into three bands; low, average, high. When these scores were correlated with the accident reports, the data showed that: 

  • 71% of those with a low Safety score had been involved in an accident.
  • 38% of those with an average Safety score had been involved in an accident.
  • Only 15% of those with a high Safety score had been involved in an accident.

The assessments were a good indicator of accident occurrence. The Safety score was also shown to predict the frequency of driver-related accidents that a driver in this organization is likely to be involved in.

It was shown that: 

  • Those with a low Safety Score are likely to be involved in an accident every 9 months.
  • Those with an average Safety Score are likely to be involved in an accident every 13 months.
  • Those with a high Safety Score are likely to be involved in an accident every 55 months.

What this means in practice

There is a clear return on investment in the assessment process.  When compared to low Safety score drivers, high Safety score drivers have:

  • 78% lower accident probability.
  • 68% fewer driving accidents per hour.
  • 3 times lower costs per hour worked.
  • 43% fewer non-driving related accidents per hour.

By using talent assessment during the hiring process to identify those most likely to have fewer accidents and driving accidents, safety would increase and costs saved.
